AfterShip configuration

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

AfterShip request contract

FastHook computes base64 HMAC-SHA256 over the raw body and compares it with aftership-hmac-sha256.

POSTPUTPATCHDELETE

AfterShip headers

Preserve aftership-hmac-sha256 when sending AfterShip 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.

aftership-hmac-sha256

Base64 HMAC-SHA256 signature over the raw body.

AfterShip setup

  1. Create an AfterShip webhook notification with the FastHook Source URL.
  2. Paste the webhook secret into FastHook.
  3. Route by tracking status, carrier, or shipment state.
