About webhooks

Webhooks allow you to be notified of Snyk system events, enabling you to build notifications and react to changes in your projects. The current implementation supports events for recurring scans of open source and container image related projects.

When events are triggered, Snyk sends HTTP POST requests to URLs you have configured for those events, with all the information you need.

Example use cases

Security SSL

Webhooks can only be configured for URLs using the HTTPS protocol. HTTP is not allowed.

Request signing

When creating a webhook, you must provide a ​secret​ - this is a string that only you know that we will use to sign our transports to you so that you can ensure they come from Snyk. Your secret should be:

  • A random string with high entropy

  • Not be used for anything else

  • Only known to Snyk and your webhook transport consuming code

All transports sent to your webhooks will have a ​X-Hub-Signature ​header, which contains the hash signature for the transport. The signature is a HMAC hexdigest of the request body, generated using sha256 and your secret as the HMAC key.

X-Hub-Signature​always starts with​ sha256=
