Paddle Source Configuration

Paddle sources receive billing, subscription, transaction, product, and customer webhooks with Paddle-Signature verification.

Paddle configuration

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

Paddle request contract

FastHook verifies paddle-signature by signing timestamp + ':' + raw body with HMAC-SHA256.

Paddle headers

Preserve paddle-signature when sending Paddle 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.

paddle-signature

Semicolon-separated ts and h1 signature values.

Paddle setup

  1. Create a Paddle notification destination with the FastHook Source URL.
  2. Paste the endpoint secret key into FastHook.
  3. Keep sandbox and production Paddle endpoints separate.
