Paystack Source Configuration

Paystack sources receive transaction, transfer, subscription, refund, invoice, and dispute webhooks with Paystack signature verification.

Paystack configuration

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

Paystack request contract

FastHook computes HMAC-SHA512 over the raw request body using the configured secret key and compares it with x-paystack-signature.

POSTPUTPATCHDELETE

Paystack headers

Preserve x-paystack-signature when sending Paystack 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-paystack-signature

HMAC-SHA512 hex signature over the event payload.

Paystack setup

  1. Set the Paystack webhook URL to the generated FastHook Source URL.
  2. Paste the Paystack secret key into FastHook.
  3. Route by event name such as charge.success, transfer.failed, or subscription.disable.
