Webhooks

Use webhooks to react to events that happen in your customers' KYC and KYB. Webhooks are a low-effort way to build integrations that extend Synaps's functionality.

warning

We don't disclose any private information through the webhook. You should always make a call to the API in order to fetch user sensitive data.

info

We use Hookdeck to ensure reliable webhook delivery.

If you need to whitelist IP addresses for security purposes, you can find a list of IPs here.

We are sending a secret value as a query parameter in the POST request.

This secret is unique to your app and is available in your manager. Check this value each time you receive a webhook to make sure that Synaps is the one who sends this request.
