Source type
Razorpay Source
Razorpay sources receive payment, order, subscription, invoice, payout, and settlement events with signature verification.
When to use this source type
Choose the RAZORPAY source type when Razorpay is the system sending webhook requests into FastHook. The source type keeps sender-specific setup close to the source: accepted methods, verification headers, challenge handling, and the exact credential fields are documented together so operators do not need to translate a generic HMAC form into a provider-specific contract.
FastHook verifies the source before accepted traffic is queued. A valid request is stored with verified: true, then connections route it to destinations. A bad signature, wrong token, or missing provider header is rejected as SOURCE_AUTH_FAILED. A method outside the allowed set is rejected as SOURCE_METHOD_NOT_ALLOWED.
FastHook configuration
In the dashboard, create a source, set Source Type to Razorpay, keep Authenticate enabled when verification is required, and fill the fields below.

This source accepts only the methods listed below. Keep the set narrow so provider mistakes and accidental test calls are visible as rejected requests instead of being silently accepted.
Headers and verification
FastHook verifies the provider-specific values below before the request is accepted. The comparison is done against the raw inbound request body or the exact provider-specific signing input described here.
x-razorpay-signatureHMAC-SHA256 hex signature over the raw body.
FastHook computes HMAC-SHA256 hex over the raw body and compares it with x-razorpay-signature.
Provider setup checklist
- Create a Razorpay webhook and point it to the FastHook Source URL.
- Copy the webhook secret into FastHook.
- Filter by event name when different payment events should go to different receivers.
- Open Razorpay webhooks documentation when you need the provider's event list, dashboard steps, or retry policy.
Troubleshooting
- No request appears: the provider is not calling the generated FastHook Source URL, the source URL was copied before saving, or the provider has not completed its setup validation.
- 405 method rejected: the provider sent a method outside
POST, PUT, PATCH, DELETE. Edit the source only if the provider documentation says that method is expected. - 401 source auth failed: check the configured FastHook field, the provider signing secret, and the header names listed on this page.
- Signature mismatch: make sure the provider signs the same public Source URL it calls and that no proxy, parser, or manual resend changed the raw request body before FastHook received it.
