Securely verify webhook requests with separate signing keys

Webhook requests from Send and receive data actions now support verification using a separate signing key distinct from reporting webhook keys. The new key is accessible in Workspace Settings under API & webhook credentials for users with Admin, Manager, and Author roles.

You can now verify webhook requests sent through our Send and receive data actions using a key that is separate from your reporting webhooks. To find the signing key in your workspace, go to Settings > Workspace Settings > API & webhook credentials and select the Webhook Signing Key tab. Users with the Admin, Manager, and Author roles can view this key. You can continue to find the key for your reporting webhooks in Integrations > Reporting webhooks.
