Zendesk configuration

Create a Zendesk source, keep POST and PUT and PATCH and DELETE enabled, and provide the configured Webhook Signing Secret values for provider signature. FastHook uses these settings to validate each Zendesk delivery before it enters the routing workflow.

Zendesk request contract

FastHook signs timestamp + raw body with HMAC-SHA256 and compares the base64 digest to x-zendesk-webhook-signature.

POSTPUTPATCHDELETE

Zendesk headers

Preserve x-zendesk-webhook-signature, x-zendesk-webhook-signature-timestamp when sending Zendesk test deliveries. FastHook evaluates this request context before accepting the payload, so missing or modified values remain visible as rejected requests instead of routed events.

x-zendesk-webhook-signature

Base64 HMAC-SHA256 signature.

x-zendesk-webhook-signature-timestamp

ISO timestamp concatenated with the raw body before signing.

Zendesk setup

  1. Create a Zendesk webhook with the FastHook Source URL.
  2. Paste the Zendesk signing secret into FastHook.
  3. Use tags, ticket ids, or event types for downstream routing.
