Great! Now let's test your webhook. Try using the interface I created earlier - it should work now that you've configured it properly.

But first, let me create a simple test to make sure everything is working:

Click the "Test Webhook Now" button and let me know what happens!

If it works, you should see a green success message. If it still fails, we'll know exactly what the error is and can fix it.

Also, check your n8n workflow - you should see the test data come through if everything is working properly.

Let me create a better diagnostic tool to see exactly what's going wrong:

Click "Run Full Diagnostics" - this will test your webhook in 4 different ways and show you exactly what's happening.

While that's running, please also check these things in your n8n:

1. Is your workflow ACTIVE? (there should be a toggle switch that's turned ON)
2. Did you change the HTTP Method from GET to POST?
3. Are you seeing any requests in your n8n execution log?

The diagnostics will tell us exactly what error we're getting and help us fix it!
