Chain the requests: Return to the Tests tab of the first request to capture the data required for the second request. Use collection variables this time. Step through the workflow by running each request one at a time to ensure you are getting and setting the variables properly and passing the data correctly.
In that scenario, you need to extract and store some data (name, email, id) from the previous request’s response.
This needs to be stored as a Collection level variable. These variables need to be used in the request body of the second request using the "{{...}}" placeholders.
