azure logic app & http step response

Question

I have 2 HTTP actions, one after another in a logic app, how do I read the response from a previous HTTP action in the second HTTP action?

First HTTP call (REST) returns a response in JSON format -

{

   "authResult": {

      "isPasswordExpired": true,

      "authToken": "cxxcxcxc",

      "message": "Login Successful"
   }
}

I want to send authtoken from the result in second http action as authorization header.

Answer 1

As Derke Li mentioned that we could use exression or Parse Json to do that. I also do a demo about how to use the Parse JSON action.

1.Add the Parse Json action after the first Http action

2.Add the parse content and click on the button "Use sample payload to generate schema" and that will pop a new window. Paste in your "authResult" json. As seen in the below image.

3.Then we could pick the token from the dynamic content.

4.We could check the result.

Answer 2

There are two ways you can do this.

1. Use expression to directly reference the property. @body('NameOfFirstHTTPAction')?['authResult']?'[authToken]

2. Add a "Parse JSON" action in between the two HTTP action, and provide a sample response of the first HTTP action to generate a schema. Then, in the second HTTP action, you will see authToken as a token from the dynamic content picker for you to reference.
