Sending email from Livestorm with Volanea is best handled through a webhook-driven server-side relay: Livestorm records a registration, your endpoint validates and maps the payload, and Volanea sends the resulting transactional message. This approach does not require—and should not imply—a native Livestorm marketplace app or plugin.

Livestorm is the source of webinar and event activity. Volanea is the delivery layer for messages such as registration confirmations, event reminders, replay notifications, waitlist updates, and post-event follow-ups. The missing piece is a trusted middleware endpoint that can receive the Livestorm event and make an authenticated REST request to Volanea.

That distinction matters. A browser, a public landing page, or a client-side automation script must never hold an email-provider API key. The send must happen on infrastructure you control: a serverless function, an application backend, an automation platform with protected connections, or another private integration layer.

The right integration pattern

Livestorm does not need a native Volanea listing for this workflow. Its outbound event capability can notify an HTTPS endpoint when a relevant resource changes, while your application decides whether a notification should become an email.

For a registration email, the practical trigger is the creation of a person record for an event registration. In Livestorm's API model, people are registrants or contacts associated with an event, and webhook notifications identify the resource event that occurred. A webhook for a newly created person is the useful starting point because it represents the moment a registrant has supplied an email address and completed the registration flow.

The architecture is deliberately simple:

  1. A participant registers for a Livestorm event.
  2. Livestorm emits a person-created webhook to an HTTPS URL you operate.
  3. Your endpoint verifies the request, normalizes the payload, and checks whether it has already handled that registration.
  4. Your endpoint calls Volanea's REST API using an API key stored only in server-side environment variables.
  5. Volanea delivers the confirmation email and returns a message identifier that you log with the Livestorm person and event identifiers.

This gives you flexibility that a one-size-fits-all native integration would not. You can send a different email for each event type, suppress a message when a person is already known, select a localized template, route leads to a CRM, or delay a reminder until a defined time before the session.

Choose the Livestorm trigger carefully

The first design decision is not "which email template should we send?" It is "which lifecycle event proves that sending is appropriate?"

For most confirmation workflows, use the webhook corresponding to a newly created person or registrant. It happens close to registration and provides the recipient identity needed to send an email. Do not use a page view, a calendar click, or a frontend form event unless your system owns and validates that event independently. Those signals are easier to duplicate, abandon, or spoof.

Registration confirmation: person created

A person-created notification is appropriate for messages such as:

  • "You are registered" confirmations.
  • Branded event preparation instructions.
  • Requests to complete required information outside Livestorm.
  • A custom confirmation for registrations created through an embedded or partner flow.
  • Internal sales notifications when a high-value registrant joins a named event.

Before enabling the send, decide whether Livestorm's own registration email is already serving the same purpose. If it is, avoid sending a second near-identical confirmation. Your Volanea message should add a meaningful purpose: branded onboarding, a resource pack, a qualifying question, an account-specific instruction, or a notification that comes from your own product domain.

Attendance and session events: use for follow-up, not confirmation

For post-event messages, an attendance-related event can be a better source signal than registration. A person may register but never attend. If the message is "Thanks for attending," base it on an attendance record or another session-participation signal rather than assuming a registrant watched the event.

Likewise, a session-end event can be useful for sending a replay or summary after an event finishes. However, a session-level event does not, by itself, tell you which individual should receive the email. You will usually need to query your attendee data or have previously stored registration records before fan-out.

Treat webhook names as contracts, not guesses

Configure only event types that Livestorm exposes in your workspace and webhook setup. Product plans, account configuration, and webhook options can affect which resources or payload fields are available. Capture a real test delivery before writing production mapping logic, and keep that fixture in your repository.

This is especially important for custom registration fields. A field might be absent because the attendee did not answer it, because it was not enabled for that event, or because the account does not expose the same data through the selected integration path. Your code should distinguish an absent optional field from a malformed webhook.

What the Livestorm webhook payload should provide

Livestorm's API uses resource-oriented data, so the core information your handler needs is the resource type, the person identifier, and person attributes such as email and name. Webhook envelopes can include event metadata around that resource. Do not assume every delivery contains every optional field, and do not build logic around a display label that could be changed by an event administrator.

A representative person-created payload looks like this structurally:

{
  "event": "people.created",
  "data": {
    "type": "people",
    "id": "person_01HXYZ...",
    "attributes": {
      "email": "maya@example.com",
      "first_name": "Maya",
      "last_name": "Lopez",
      "created_at": "2026-09-21T15:04:05Z"
    },
    "relationships": {
      "event": {
        "data": {
          "type": "events",
          "id": "event_01HABC..."
        }
      }
    }
  }
}

Use that shape as a mapping model, not as permission to hard-code a sample identifier or assume every account returns the same optional relationship object. Save the raw JSON from a test registration and adjust the extraction paths to the payload delivered to your endpoint.

For a confirmation email, the minimum viable mapping is straightforward:

Livestorm dataVolanea email use
data.attributes.emailRecipient address
data.attributes.first_namePersonalization variable
data.attributes.last_namePersonalization variable or CRM context
data.idIdempotency and audit key
event identifier or event relationshipTemplate selection and reporting tag
webhook event nameValidation that the handler received the expected lifecycle event

Never use an email address as your only idempotency key. A person can register for two distinct events with the same address, and a registration can be updated or recreated. Pair the Livestorm person identifier with the event identifier and the email-purpose name, such as registration-confirmation.

Build a private webhook relay

A Livestorm webhook is an inbound HTTP request. Volanea is an outbound REST request. The relay sits between them because it solves three separate security and reliability problems:

  • It keeps the Volanea API key outside of Livestorm configuration, browser code, and public repositories.
  • It transforms Livestorm's resource payload into your email template data.
  • It returns a fast acknowledgement to Livestorm while handling retries, idempotency, and provider errors safely.

A serverless function is often enough. Use a route in an existing application, a function on your hosting platform, a worker, or a lightweight container service. The handler must be reachable over HTTPS and should accept only the webhook method and content type that your Livestorm configuration sends.

Store secrets in environment variables

The Volanea API key belongs in the secret manager or encrypted environment settings of the system running the relay. For example:

VOLANEA_API_KEY=...
VOLANEA_SEND_URL=...
LIVESTORM_WEBHOOK_SECRET=...

The relay reads these values at runtime. They must not be included in a JavaScript bundle, a public frontend environment variable, a Livestorm registration form, an email-template URL, or a client-visible automation configuration.

If your Livestorm webhook configuration supports a signing secret or authentication method, configure it and verify it in the relay before parsing the body. If it does not offer signed delivery for your account or workflow, use a high-entropy secret in the webhook URL, restrict access at your edge where practical, and add an application-level verification strategy. Do not rely on obscurity alone; rotate the endpoint secret if it is exposed.

Why the Volanea key should not live on the Livestorm side

Livestorm is the event source, not the email-sending credential store. A webhook destination is generally a URL to call, not a secure place to run arbitrary server-side transformation code with private provider credentials. Even where a third-party automation tool can store credentials, use its protected connection or secret facility rather than placing a key in a URL parameter or a visible field.

Putting a Volanea key in a client-visible configuration creates a direct account-takeover risk. Anyone who can inspect the page, browser network requests, client bundle, shared screenshot, or incorrectly configured repository could send messages from your account, consume your sending allowance, and damage your sender reputation.

For implementation details on credentials, sending endpoints, and accepted request fields, use the Volanea API reference and setup guides as the source of truth for your account.

Map the webhook to a Volanea email request

The exact Volanea sending URL and request schema should be taken from your account's current API documentation rather than copied from another email provider. Do not substitute a Mailgun, Mailjet, Resend, or SendGrid endpoint: their authentication methods and JSON schemas differ.

The following Node.js example shows the full integration pattern with the Volanea call isolated in one function. Set VOLANEA_SEND_URL to the current REST send endpoint documented for your Volanea account, and align the request body keys with the documented Volanea send schema. The important part is the mapping, validation, idempotency key, and private Authorization header.

import express from "express";

const app = express();

// Keep the raw body if your Livestorm webhook verification method requires it.
app.use(express.json({ limit: "256kb" }));

const sent = new Set(); // Replace with Redis or a database in production.

function requireString(value, label) {
  if (typeof value !== "string" || value.trim() === "") {
    throw new Error(`Missing required Livestorm field: ${label}`);
  }
  return value.trim();
}

async function sendWithVolanea({ to, firstName, eventId, personId }) {
  const apiKey = process.env.VOLANEA_API_KEY;
  const sendUrl = process.env.VOLANEA_SEND_URL;

  if (!apiKey || !sendUrl) {
    throw new Error("Volanea sending credentials are not configured");
  }

  // Replace only the field names below if your current Volanea API reference
  // uses different names. Do not change this into client-side code.
  const volaneaPayload = {
    from: {
      email: "events@example.com",
      name: "Example Events"
    },
    to: [{
      email: to,
      name: firstName || undefined
    }],
    subject: "You are registered",
    html: `<p>Hi ${escapeHtml(firstName || "there")},</p>
           <p>Your webinar registration is confirmed.</p>`,
    text: `Hi ${firstName || "there"},\n\nYour webinar registration is confirmed.`,
    tags: ["livestorm", "registration-confirmation", `event:${eventId}`],
    metadata: {
      livestorm_person_id: personId,
      livestorm_event_id: eventId
    }
  };

  const response = await fetch(sendUrl, {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${apiKey}`,
      "Content-Type": "application/json",
      "Idempotency-Key": `livestorm:${eventId}:${personId}:registration-confirmation`
    },
    body: JSON.stringify(volaneaPayload)
  });

  const responseText = await response.text();

  if (!response.ok) {
    throw new Error(`Volanea send failed (${response.status}): ${responseText}`);
  }

  return responseText;
}

function escapeHtml(input) {
  return String(input)
    .replaceAll("&", "&amp;")
    .replaceAll("<", "&lt;")
    .replaceAll(">", "&gt;")
    .replaceAll('"', "&quot;")
    .replaceAll("'", "&#039;");
}

app.post("/webhooks/livestorm", async (req, res) => {
  try {
    const payload = req.body;

    // Confirm the actual event value against a captured Livestorm test delivery.
    if (payload?.event !== "people.created") {
      return res.status(204).end();
    }

    const person = payload.data;
    const personId = requireString(person?.id, "data.id");
    const email = requireString(person?.attributes?.email, "data.attributes.email");
    const firstName = person?.attributes?.first_name || "";
    const eventId = requireString(
      person?.relationships?.event?.data?.id,
      "data.relationships.event.data.id"
    );

    const dedupeKey = `${eventId}:${personId}:registration-confirmation`;

    if (sent.has(dedupeKey)) {
      return res.status(200).json({ status: "duplicate_ignored" });
    }

    // Reserve before sending. In production, make this an atomic database or Redis operation.
    sent.add(dedupeKey);

    await sendWithVolanea({
      to: email,
      firstName,
      eventId,
      personId
    });

    return res.status(202).json({ status: "accepted" });
  } catch (error) {
    console.error("Livestorm webhook processing failed", error);
    // Return a non-2xx response only when you want the source to retry.
    return res.status(500).json({ error: "email_not_sent" });
  }
});

app.listen(process.env.PORT || 3000);

This example intentionally keeps the Volanea endpoint in a server-side environment variable. That avoids pretending that another provider's endpoint is a Volanea endpoint and makes upgrades easier if your account moves between API versions. Before deploying, compare the from, to, content, tags, metadata, authentication, and idempotency fields with the current Volanea documentation.

Use templates instead of HTML strings in production

Inline HTML is useful for demonstrating field mapping, but most production teams should use an approved transactional template. Keep the template identifier and its variables in the server-side sender function. This reduces markup bugs, keeps branding consistent, and lets non-engineering teams update copy without editing webhook logic.

The mapping remains the same: Livestorm provides the event data; the relay selects a template; Volanea receives the recipient, template data, and tracking metadata.

Make duplicate prevention a first-class feature

Webhook systems are at-least-once delivery systems in practice. A source can retry because it did not receive a timely success response, because your endpoint temporarily failed, or because a network interruption occurred after the provider processed the request but before it observed your response.

That means duplicate email prevention cannot be an afterthought.

Use a durable idempotency record

The in-memory Set in the example is only for clarity. It disappears when a serverless function restarts, does not work across multiple instances, and cannot protect against concurrent deliveries. Production code should use a durable store with an atomic insert or lock.

A practical idempotency record contains:

  • livestorm_person_id
  • livestorm_event_id
  • purpose, such as registration-confirmation
  • status, such as processing, sent, or failed
  • Volanea message identifier, if returned
  • first received timestamp and last updated timestamp

Create a unique database constraint across person, event, and purpose. If an insert conflicts, return a successful acknowledgement without sending again. If the previous attempt failed before Volanea accepted the request, permit a controlled retry according to your own retry policy.

Respond quickly, send safely

Do not make the webhook request wait for slow downstream work when you can avoid it. A robust design validates the payload, writes a durable job, and acknowledges the webhook quickly. A worker then performs the Volanea send and records the result.

For lower-volume workflows, sending synchronously can be acceptable if the endpoint remains reliably fast. But it is still important to set an outbound timeout, log provider failures, and understand whether a failed or delayed acknowledgement will cause Livestorm to retry the delivery.

When this breaks

The fragile point in this integration is the hop between Livestorm's webhook delivery and your email relay. Plan for failures there rather than treating a webhook as a guaranteed one-time instruction.

Livestorm retries can create duplicate sends

If Livestorm retries after a timeout or non-success response, your endpoint may receive the same person-created event more than once. A retry can happen even if your original handler already sent the email but did not return its response in time.

Mitigation: make idempotency durable and atomic. Reserve the dedupe key before sending, include the same business key in Volanea metadata, and—where Volanea supports it—use its idempotency facility as a second layer of defense.

Webhook timeouts can be mistaken for send failures

A timeout between Livestorm and your endpoint says only that the delivery was not acknowledged. It does not necessarily say that Volanea failed to accept the email. Retrying blindly can produce duplicates.

Mitigation: separate acknowledgement from delivery work. Persist an incoming webhook job, return promptly, and make the worker query its own records before attempting another send. Store the Volanea response or message ID whenever a send succeeds.

Optional payload fields may be missing

First names, last names, custom answers, event relationship information, and other fields can be absent. This can vary by the event's registration form, by attendee behavior, or by the capabilities exposed to your Livestorm account and integration route.

Mitigation: require only the fields necessary for the message. For a basic confirmation, that is normally a valid recipient email plus enough identifiers to deduplicate. Use safe defaults for personalization, such as "there," and fail closed when the email address or required event context is missing.

Your event may not be enabled or available on the plan

If the expected outbound webhook event is not available in the Livestorm account, do not simulate a direct integration with frontend code. Use a supported middleware route instead: configure a Livestorm-to-Zapier or Livestorm-to-Make workflow if the account exposes the required trigger, then have that platform call your secure relay or Volanea through a protected connection.

The same security rule applies. The Volanea key belongs in the protected credentials area of the automation platform or, preferably, in your own relay's secret store. It should not be passed through a public webhook URL, a spreadsheet column, or a browser-side action.

A successful API response does not guarantee inbox placement

A provider acceptance response means the message entered the sending pipeline; it does not prove that it reached the inbox. Deliverability depends on sender authentication, sending domain alignment, recipient quality, content, complaint rates, and engagement.

Mitigation: use a verified sending domain, configure the DNS records Volanea requires for your domain, monitor bounces and complaints, and avoid sending transactional messages to addresses that have unsubscribed from the relevant communication category. Before sending campaigns or event follow-ups at scale, validate questionable addresses with an email address verification tool.

Test the full path before going live

A production-ready test is more than submitting a registration form once. Test the system as a sequence of observable steps.

  1. Create a dedicated test event and register with an inbox you control.
  2. Capture the exact Livestorm webhook payload at your relay.
  3. Confirm that the expected event value, person ID, email field, and event relationship are present.
  4. Verify the relay rejects a payload without a recipient email.
  5. Replay the same webhook twice and confirm exactly one Volanea send occurs.
  6. Simulate a Volanea 429 or 500 response and confirm your retry policy does not create uncontrolled duplicates.
  7. Check the delivered message headers, sender domain, reply-to address, rendering, unsubscribe behavior where applicable, and tracking metadata.
  8. Review your logs to ensure a support teammate can trace a delivered email back to the Livestorm person and event.

Keep a sanitized version of the captured webhook payload in your test suite. It is more useful than a generic mock because it protects the real field paths your integration depends on.

Operational practices that keep the integration maintainable

Webhook-to-email flows often start as a small convenience and become business-critical. A webinar team may rely on them for VIP onboarding, compliance notices, product demos, partner communications, or sales qualification. Build enough observability from the beginning to understand what happened to a specific recipient.

Log structured fields rather than only human-readable strings. At minimum, log the webhook event, Livestorm person ID, Livestorm event ID, dedupe key, recipient domain rather than the full recipient address where possible, Volanea response status, message ID, and processing duration.

Avoid storing raw email addresses indefinitely in application logs. They are personal data. Limit access, redact sensitive values, define retention periods, and document the lawful basis and consent expectations for the messages you send.

For high-volume programs, add a queue between webhook ingestion and Volanea sending. Queues provide back-pressure when registrations spike, make retry scheduling explicit, and protect your webhook endpoint from becoming a bottleneck. They also let you prioritize time-sensitive confirmation messages over lower-priority internal notifications.

Alternatives when a direct webhook relay is not the best fit

A custom relay is the strongest option when you need control, auditability, custom templates, and dependable duplicate prevention. It is not the only option.

Zapier or Make as middleware

If your Livestorm setup exposes a supported trigger through Zapier or Make, use that trigger to start an automation. The automation can filter by event, format a name, add data to a CRM, and call a private endpoint.

For simple workflows, the automation platform may be the entire relay if it supports securely stored Volanea credentials and the exact REST request you need. For important confirmation flows, consider keeping a small owned endpoint for idempotency and logging even if Zapier or Make provides the trigger. Automation retries can also generate duplicate actions, so the dedupe design remains necessary.

Scheduled reconciliation

For a daily summary, a webhook is not always necessary. A scheduled job can query the relevant Livestorm records, determine who has not received a message, and send through Volanea in batches. This pattern is useful for reporting, replay campaigns, and recovery from an outage, but it is less immediate than a registration webhook.

Use Livestorm-native messages where they fit

If the required message is a standard webinar notification and Livestorm already sends it reliably, use the native notification instead of duplicating it. Add Volanea when you need communication that belongs to your product or customer lifecycle: account setup, custom resource delivery, lead routing, multilingual content, or cross-system transactional events.

Conclusion

To send email from Livestorm with Volanea, treat Livestorm as the source of a trustworthy registration or attendance event and Volanea as the authenticated sending service. The connection between them should be a private relay, not a browser-side shortcut and not an invented marketplace integration.

Start with a person-created registration event, capture a real payload, map only the fields you need, store the Volanea API key in server-side secrets, and make duplicate prevention part of the initial implementation. Once that foundation is in place, the same pattern can power confirmations, reminders, attendee follow-ups, internal alerts, and event-specific lifecycle email without exposing credentials or sacrificing deliverability controls.

FAQ

Can I install a native Volanea app from the Livestorm marketplace?

No. This workflow should be implemented through Livestorm's supported outbound event or automation capabilities plus a secure middleware layer. Do not represent it as a native Livestorm marketplace plugin.

What Livestorm event should trigger a registration email?

Use the person-created or registrant-created event that your Livestorm webhook delivery actually emits after registration. Capture a real test payload and confirm the event name and field paths before deploying.

Where should I store my Volanea API key?

Store it only in server-side environment variables, a cloud secret manager, or a protected automation-platform connection. Never place it in frontend code, a public webhook URL, a Livestorm form, or a repository.

How do I stop duplicate confirmation emails?

Create a durable idempotency key from the Livestorm event ID, person ID, and email purpose. Use an atomic database or cache operation to reserve that key before calling Volanea.

What if a Livestorm payload does not include a first name or custom field?

Treat optional fields as optional. Use safe defaults for personalization, and reject or quarantine only messages that are missing fields essential to safe delivery, such as the recipient email address.
