5) Creating Chained Requests

It is possible to configure Postman to Chain Multiple Requests together in order to "Pass" Values from an earlier response into the Body of another call.

Configure your collection
Perform any functions required to be performed on every single call as part of the collection

Collection Configuration Script

//Demonstrate a function call to confirm that the response is a 200 Response/ Successful response.
pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

//All responseses are required to  be converted to JSON in Order to be read, and Passed through as values.
//This is perfermed on an individual call level, but outputting this as a JSON Response in your developer tools will help identify the correct required variable
var responseJson = xml2Json(responseBody);
console.log(responseJson);

Configure your Login Procedure and assign Variables required

Login "Tests" Code

//In Order to refer to the JSON Response the Variable must be declared on a Local Request Level.
var responseJson = xml2Json(responseBody);


//Set a Global Variable for Session Information.
//Variables can also be declared on a Environment & Collection level
    //pm.environment.set
    //pm.collection.set

//pm.globals.set("variable_key", "variable_value")
        //variable_value == variable.path.element
        //variable == responseJson['s:Envelope']['s:Body']
        //path == LoginResponse.LoginResult
        //element == AccountID

pm.globals.set("AccountID",responseJson['s:Envelope']['s:Body'].LoginResponse.LoginResult.AccountID); 
pm.globals.set("DistributorID",responseJson['s:Envelope']['s:Body'].LoginResponse.LoginResult.DistributorID); 
pm.globals.set("Expires",responseJson['s:Envelope']['s:Body'].LoginResponse.LoginResult.Expires); 
pm.globals.set("Key",responseJson['s:Envelope']['s:Body'].LoginResponse.LoginResult.Key); 
pm.globals.set("UserID",responseJson['s:Envelope']['s:Body'].LoginResponse.LoginResult.UserID);

Subsequent calls can now use information from the response and output this into subsequent calls
