I did the following procedure and it is not working:
I created a flow with, and placed the start block with “Takes input of any type”.
I created a Webhook and published it.
I created an HTTP POST request with the WebHook URL
When I try to send a manual POST request, or schedule it via Monitor, it doesn’t work. It returns 200 and the message below, but my flow is not executed.
{
"event": "6786c64e213e7357e532e853",
"timestamp": 1736885837900,
"state": "processing",
"message": "A flow run has started for this webhook call"
}
If I send it via WebHook Preview, it works perfectly.
The 200 response code just indicates that the flow has been triggered successfully. The flow runs as an asynchronous process after that point. The preview runs the flow locally as opposed to on our cloud, so if you need to be on a VPN for your APIs or refreshing OAuth tokens via the authorization tab, your flow will fail in the cloud.
If you press the three dots next to the publish button below your flow url, you can view the published version, then trigger your flow and it should show you the live logs of your flow including any errors.
Let me know if you run into any trouble finding the issue.
Looks like the endpoints have some restrictions that are fine when being run from your computer, but not the Postman Cloud. Are these private endpoints?
I got the same situation going on where my webhook preview works fine, when I throw my webhook into a POST collection, I always get a 200 OK, I am using OAuth 2.0, even if I delete my secret and clientID I still get the 200 OK, it’s clearly not working… If I can just figure out how to get my webhook I can finally get my flows to automate, certainly been the biggest challenge to accomplish as a new comer to POSTMAN.
I really would like to get my flows working with webhooks, what could I be missing? I get 200 OKs regardless if I have secrets or not for OAuth 2.0. Doesn’t seem to really even be communicating which I find odd. My preview flow the webhook executes and seems to be working, however the collection doesn’t work with using a POST request to my webhook URL.
Webhooks will always return 200 when you run them from the cloud, the return value does not indicate if the flow succeeded or not. The 200 just indicates Postman Cloud has received the request to run successfully.
One way you can debug what is happening:
Open the flow in question
On the canvas, Ensure you have Log Blocks throughout your flow to get a sense of what is happening when it runs
In the Sidebar, Click the three dots next to the webhook
In the Sidebar, Click “View published version”
In the Toolbar, Click “View live logs”
Once you are viewing the live logs, you can then run the flow and watch what happens in the console below the canvas to figure out what the issue might be. Hopefully this helps!
I appreciate the reply, I have looked at the logs many times but it doesn’t tell me anything that sticks out. I get “A flow run has started for this webhook call”. No warnings or errors running it within the flow directly and the collection. Any other suggestions? I appreciate the time!
Running in the flow is successful and the flow works in preview. I tried both GET and POST with same outcome. The URL matches the webhook flow that I’m executing within the collection.
