Create and manage Lusha webhook subscriptions

Webhook subscriptions tell Lusha which entities to watch and where to send notifications when signals fire. Each subscription links one entity (a contact or company) to a webhook URL and a set of signal types. You can manage up to 25 subscriptions per request and monitor all deliveries through audit logs.

Setup flow

Generate your account secret

Call POST /api/account/secret/regenerate to create your account-level webhook secret. Store it securely - it is displayed only once and is required to verify every incoming delivery.

POST https://api.lusha.com/api/account/secret/regenerate

Create a subscription

Call POST /api/subscriptions with a defaults object (containing your webhook url and, optionally, a default entityType and signalTypes) and a subscriptions array with one entry per entity you want to watch. Each entry requires at least entityId, and can override entityType, signalTypes, or name.

Test the subscription

Call POST /api/subscriptions/{id}/test to send a test payload to your endpoint and confirm the full delivery pipeline works before going live.

Go live and monitor

Your endpoint will now receive real-time deliveries. Use GET /api/audit-logs to monitor delivery success rates, inspect failures, and reactivate any disabled subscriptions.

Create subscriptions

POST /api/subscriptions Creates one or more webhook subscriptions for real-time signal notifications.

You can create up to 25 subscriptions per request. Your account must have a webhook secret before deliveries can be received.

Delivery and reliability

Lusha retries failed deliveries automatically:

3 retry attempts with exponential backoff
Auto-disable: a subscription is disabled after all retries are exhausted
All delivery attempts are recorded in audit logs

Webhook payload examples

When a signal fires, Lusha sends a POST request to your webhook URL with a JSON body. Below are examples for a contact promotion signal and a company news signal.

Required acknowledgment response

Your endpoint must respond within 10 seconds with an HTTP 2xx status and the following JSON body:

{
  "received": true,
  "timestamp": "2026-02-05T10:30:45.123Z",
  "webhookId": "f3b87e05-0402-4f3e-8e26-6a38fd0ad62c"
}

Field	Type	Description
`received`	boolean	Must be `true`
`timestamp`	string	ISO 8601 timestamp of when your server received the request
`webhookId`	string	The `id` value from the incoming webhook payload

A non-2xx response triggers the retry mechanism. After 3 failed retries the subscription is automatically disabled.

Return the acknowledgment before performing any heavy processing. Queue the payload for async handling if needed:

app.post('/webhook', async (req, res) => {
  // 1. Verify signature first
  if (!verifyWebhookSignature(req)) {
    return res.status(401).json({ error: 'Invalid signature' });
  }

  // 2. Queue for async processing
  await queueWebhook(req.body);

  // 3. Acknowledge immediately
  res.status(201).json({
    received: true,
    timestamp: new Date().toISOString(),
    webhookId: req.body.id
  });
});

List subscriptions

GET /api/subscriptions Returns all webhook subscriptions for your account with pagination support.

Results are sorted by createdAt in descending order (newest first)
Default page size: 10; maximum: 100
Use offset to paginate through large result sets

The webhook secret is never returned in list responses for security.

Get a subscription

GET /api/subscriptions/{id} Returns a single webhook subscription by its ID.

Update a subscription

PATCH /api/subscriptions/{id} Updates an existing subscription. All fields are optional - include only the fields you want to change.

Reactivating a disabled subscription

If a subscription was disabled after exhausting retries, set isActive: true to reactivate it. The system automatically:

Clears the blockReason field
Clears the blockedAt timestamp
Resets the retry counter

Regenerating your account secret

Set regenerateSecret: true in the request body to rotate your webhook secret. Keep in mind:

The new secret affects all subscriptions for your account
The secret is shown only once in the response - store it immediately
The old secret is immediately invalidated

Delete subscriptions

POST /api/subscriptions/delete Deletes one or more subscriptions in a single request.

Deletion is permanent and cannot be undone.

Up to 25 subscriptions can be deleted per request
Duplicate IDs in the request are automatically deduplicated
Each subscription is processed independently; the response includes a result for each item
Invalid ID formats are gracefully handled and reported as NOT_FOUND

Test a subscription

POST /api/subscriptions/{id}/test Sends a test payload to your webhook endpoint without consuming credits.

Run a test delivery before going live to confirm your endpoint handles signatures and acknowledgments correctly.

Choose a test mode using the mode query parameter, based on what you want to validate:

Mode	What it tests
`direct`	HTTP reachability only - validates that your URL responds correctly
`kafka`	Fanout handler only - validates message processing without a full delivery
`full`	Complete end-to-end delivery pipeline (default)

Test payloads use mock data and do not trigger credit charges.
