API Testing: Working with Variables in Postman

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. In Postman, variables play a pivotal role in enhancing flexibility and efficiency throughout the application programming interface (API) testing and development process. These variables provide a dynamic way to handle changing values, such as ports, URL app routes, or data within a request body. In this course, you will begin by working with variables, including global variables, collection variables, and environment variables, and learning when to use each type. Moving on, you explore secret variables, which keep their value hidden, and thus are ideal for storing sensitive information like passwords. You will see how you can use the UI, pre-request scripts, and tests to configure and access these variables. Next, you delve into request chaining, linking all requests in a collection such that each request depends on the previous ones in sequence. Finally, you explore the Postman command line interface (CLI). You will install this on your local machine and use it to run collections.
