   • Learn to organize requests using workspaces and collections.
   • Understand how to use collection variables to enhance efficiency.
2. Variables in Postman:
   • Explore the different types of variables (Global, Environment, Collection, Local).
   • Learn how to switch between environments using variables.
3. Authorization and Authentication:
   • Understand various authentication methods (API Key, OAuth, Bearer Token).
   • Set up authorization at the collection level.
4. Request Structure and Headers/Body:
   • Explore the structure of API requests, including methods, headers, and body formats.
   • Practice building requests with various data formats (form-data, raw, JSON).
5. Testing and Response Validation with Scripts:
   • Learn to write test scripts to validate API responses.
   • Check for correct status codes, response times, and JSON structure.
6. Advanced Features:
   • Discover how to use Postman’s Collection Runner for data-driven testing.
   • Understand mock servers and monitoring for advanced API testing.

By the end of this course, participants will:

1. Organize API Requests Effectively: Gain a strong understanding of how to use workspaces, collections, and variables in Postman.
2. Understand Authorization and Authentication: Learn how to configure and test various authentication methods.
Master API Request Structure: Develop proficiency in constructing and managing API requests, including headers and body formats.
3. Write and Execute Test Scripts: Learn how to write scripts to automate response validation and improve API testing efficiency.
