Troubleshooting HTTP Request Node Failing to Trigger Webhook in Local N8N Setup

Hi all,
I’m running a local installation of N8N on Windows 11 without Docker. I have two flows:
• Flow A: Triggered via a Webhook, accepts some parameters, and does nothing further. This flow works fine when I trigger it manually using Postman, curl, or a browser.
• Flow B: Contains an HTTP Request node that calls the webhook from Flow A. However, no matter what I try, triggering Flow B does not seem to successfully trigger Flow A.
I feel like I might be missing a simple configuration detail. Any ideas or suggestions to resolve this issue?

Below are a few things you can check:
-
HTTP Method Consistency
Make sure that the HTTP method used in Flow B’s HTTP Request node matches what Flow A’s Webhook is set up to accept. For example, if Flow A is configured to accept GET requests, then the HTTP Request node in Flow B needs to also use GET. -
Correct Webhook URL
Verify you are using the URL exactly as shown for Flow A’s webhook. If Flow A has separate Test and Production URLs, ensure you’re calling the active one. When testing a workflow, you might be using the Test URL—but remember, it’s only listening for a limited time (typically 120 seconds). For persistent workflows, use the Production URL. -
Configuration Details in the HTTP Request Node
Check that any parameters (query, header, body) you supply from the HTTP Request node in Flow B are formatted correctly. Even if Flow A accepts manual requests fine, a mismatch in method or parameter formatting from the HTTP Request node might result in Flow A not being triggered.
By verifying that Flow B is calling the correct URL with the correct method and parameters, you should be able to trigger Flow A successfully.
