How to pass a variable in a HTTP trigger using GET method

[bouillons]

Hi,

I have a need to implement a HTTP service that an external system will call using a GET request. The system will call my service with parameters in the url, for example http://server/Notification?RequestID="12345"

I created a simple flow with a trigger "When a HTTP request is received" with method GET and path /Notification

The flow generated a URL that I can call from the browser, but when I add &RequestID="12345" to the end of it, I don't see this info appear in the flow request/response.

How can I read the RequestID parameter in my flow and use it in subsequent actions ?

Hi!

Did you consider defining 'relative path' input in your trigger?

Hi @bouillons ,

As suggested by @efialttes , when you want your endpoint URL to accept parameters, specify the relative path in your trigger.

Please check this link and get more details about accept parameters in endpoint URL:
