Read body data coming back from HTTP action

[BrittanyR]

I am trying to find anything in the documentation when googling for this but unable to find any. I know it must be simple but, how do I read a specific value returned in JSON from the response body resulting from HTTP action? I got back the result successfully in HTTP action but I want to get only 1 value there and store it in a variable.

Hello Team,

Here is what you need to do after the Send an HTTP request action -

 Initialize Variable for storing the parsed ID (that we are going to do in the next steps) - 

• Add ‘Initialize Variable‘ action to initialize a variable of type, ‘String’ and name it ‘ID’

Parse JSON to Save the ID from the JSON - 

• For the ‘Content‘ in the image below, navigate to ‘Add Dynamic Content‘ line and choose the ‘Body‘ option inside the ‘Send an HTTP request to SharePoint‘ action.
• For the Schema, paste the body of Get HTTP request. You will get this from the run history.

 Apply to each

• For the ‘Select an output from previous steps‘ in the image below, navigate to ‘Add Dynamic content‘ line and choose ‘Value‘ inside the ‘Parse JSON‘ action.
• Then, add a ‘Set Variable‘ action and for the ‘Name‘, select ‘ID‘ from the drop down menu and for ‘Value’, navigate to the ‘Add Dynamic content’ line, and choose ‘ID’ inside the ‘ParseJSON‘ action.

Let me share a video tutorial on my youtube channel that will help you understand this very easily.

Navigate to 14 minutes and 39 seconds over here, where I have done exactly the same thing that you want. Only thing is I am grabbing a different entity. You can grab ID by referring the same URL.

If I'm understanding your question correctly, you should also be able to reference the value by using an expression like this:

body('HTTP_Action_name_here')?['body_element_name_here']

Without seeing your flow, I can't guess exactly what the expression would be, but hopefully you can fill in the gaps.
