When a HTTP request is received - not triggering

I have a Flow which uses the 'When a HTTP Request is received' trigger. This should trigger whenever an SMS is received in ClickSend.

However the Flow doesn't trigger when an SMS is received.





I have used Postman to manually test the trigger and it does work.





I have also tested from the ClickSend side of things using If I use the URL provided by in the ClickSend webhook, a request is received.


The webhook in ClickSend. Adding a Test reply a request when using the URL but not when using the Flow URL.The webhook in ClickSend. Adding a Test reply a request when using the URL but not when using the Flow URL.

I have also talked to ClickSend support but obviously it's working when using But then Power Automate is also working when using Postman.

Hi @DuncanIVH 


So in ClickSend you have configured the Flow HTTP url for the trigger?

Hi @abm 

yes that's correct. The URL is the webhook is set as the one from the Flow trigger.

Did you find a solution to this problem? Im having the exact same issue and have done the exact same troubleshooting steps you have. Still the http trigger is not hit.

@matt-gowland unfortunately not. Are you using ClickSend or a webhook from something else?


If using ClickSend I worked around it by polling ClickSend instead. For me, instant notifications wasn't important so I run the Flow once a week, poll the delivery reports and then there's an API to mark them as read at ClickSend.

Dam. I am using a different SAAS application but same principle - trying to send a web request on an event in the SAAS app - confirmed the exact same request works using Postman, confirmed the SAAS application is sending the request exactly as expected to

Ive opened a support case with Microsoft but they're generally pretty useless 🙂

Might have to resort to doing it the old fashioned way and run up a node.js endpoint to do what power automate should be able to do 😞
