Test webhook for integration verification

Webhook that is sent once to verify your webhook endpoint is correctly set up. This is sent when you configure or update your platform settings with a webhook URL.

Authentication

The webhook includes a signature in the X-Grid-Signature header that allows you to verify that the webhook was sent by the Grid API. To verify the signature:

1. Get the Grid public key provided to you during integration
2. Decode the base64 signature from the header
3. Create a SHA-256 hash of the request body
4. Verify the signature using the public key and the hash

If the signature verification succeeds, the webhook is authentic. If not, it should be rejected.

This webhook is purely for testing your endpoint integration and signature verification.
