In Chapter 9, Testing Our Application Endpoints and Components, we built a Postman collection. However, it was a bit ropey as we had to rely on Python to load the new token into the Newman collection. While this was important to use as using Python as glue code between processes is a useful skill, our old version of readying a Newman collection with Python is not the cleanest approach.
