Vendor onboarding webhook intake with validation and forwarding

How it works

1. 1.A Webhook node receives POST requests on the configured path and defers the response to a Respond to Webhook node.
2. 2.A Set node extracts the request body into an input field and adds a source label identifying the template.
3. 3.An If node checks whether input is not empty to route execution.
4. 4.On the true branch an HTTP Request node POSTs to api.example.com with generic credential authentication and a placeholder body.
5. 5.Respond to Webhook nodes return JSON statuses of accepted or invalid.

Use cases

• Centralized intake endpoint for new vendor registration forms from finance admin systems.
• Lightweight validation gate before passing vendor data to an external processing service.
• Starting template to extend with notifications or approval steps after intake.

Requirements

• Configure HTTP generic credentials in n8n for the Forward To Service node.
• Replace the placeholder https://api.example.com URL and REPLACE_WITH_YOUR_VALUE body parameter.
• Activate the workflow so the webhook path becomes callable.

Setup and testing in n8n

1. Send a POST request with an empty body to the webhook path and confirm an invalid response.
2. Send a POST request with a non-empty body and verify the external service receives it and an accepted response returns.
3. Inspect the n8n execution log to confirm the correct branch was followed after validation.
