Trial Signup Webhook Intake Validation and Forwarding

How it works

1. 1.Webhook node accepts POST requests at the configured path and defers the response to a response node
2. 2.A Set node copies the request body into an input field and adds a fixed source value
3. 3.An IF node checks that the input field is not empty
4. 4.Valid input is POSTed to an external service with generic credential authentication, then a success response with status accepted is returned
5. 5.Invalid input short-circuits to a response with status invalid

Use cases

• Initial gateway to filter empty trial signup submissions before backend processing
• Centralized intake endpoint for trial signup requests from multiple forms

Requirements

• Replace the placeholder URL in Forward To Service with a real endpoint and set the placeholder body parameter
• Configure a generic HTTP credential in n8n for the Forward To Service node
• Activate the workflow before the webhook path becomes reachable

Setup and testing in n8n

1. Send a POST request with an empty body and expect an invalid response
2. Send a POST request with a non-empty body and expect an accepted response after the forwarding attempt
3. Review execution logs to inspect the outbound HTTP request result
