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

(0) ShareShare

Posted on by bouillons 302

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 @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:

    https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-http-endpoint#accept-parameters-in-endpoint-url

     

    Best Regards,

    Hi!

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

    Hope this helps
