Webhooks

Instant ID as a Service (IIDaaS) webhooks deliver real-time event notifications to your systems over HTTPS, so you don't need to poll for changes. When an event occurs, IIDaaS sends an HTTP POST request with a JSON payload to a callback URL that you configure.

Webhooks cover several categories of events:

  • Authentication: Sign-in successes and failures, useful for security monitoring, alerting, and feeding events into SIEM or compliance tools.
  • User lifecycle: Account creation, profile updates, and deletions, useful for automating onboarding, offboarding, and keeping downstream systems in sync.
  • Authenticator changes: Password resets.

Requirements and limits​

Endpoint requirements​

Your callback URL must use HTTPS and support TLSv1.2 or TLSv1.3. Versions lower than TLSv1.2 are not supported.

Response time​

Your webhook endpoint must return a success status code (2xx) within 3 seconds. If IIDaaS does not receive a successful response within that time, the delivery attempt is marked as failed.

Retry behavior​

If the callback endpoint returns a 5xx server error, IIDaaS retries the webhook delivery up to 3 total attempts.

  • The first retry happens after about 2 seconds.
  • The second retry happens after about 4 seconds.
  • Each retry includes a small random delay, so retries do not always occur at the exact same moment.

IDaaS retries webhook deliveries only for server-side failures that return a 5xx response.

Failure behavior​

If a webhook reaches 100 consecutive delivery failures, IIDaaS automatically disables it. To resume event delivery, enable the webhook again.

Configuration limit​

Each customer can configure a maximum of 20 active webhooks.
