We are happy to introduce the official Postman Collection for Postmark! If you are not familiar with Postman it is a graphical interface tool that allows you to test and share API calls at the click of a button. Our Postman collection makes it easy to try out the Postmark APIs and see the results instantly without the need to write any code. The collection includes prepopulated API calls, variables, and authorization headers, allowing users to easily test multiple API calls together. Once installed, users can import the collection by clicking the Run in Postman button and update the Collection Variables with their API tokens. With the collection's guidance, users can start testing the Email endpoint and experiment with other fields available in the API call. The collection also includes a set of variables called Collection Variables that may be required for API calls to work. By following these steps, users can easily test Postmark APIs without writing any code.
