I've created a simple flow that when an Item is Created in Sharepoint, it obtains the Tracking Number, posts it to an API through HTTP Post and then upon Success the HTTP Get action occurs and Parse JSON is my next step to get the results of the status of a package.

I tried another compose but can't see how to identify the variables.
