About Postman

Postman helps teams explore, document, and test APIs through organized requests and reusable workflows. Build a collection against a local service, manage variables and authentication carefully, and turn repeatable request checks into a reviewable test report.

Postman Course Objectives

  • Organize API requests into maintainable collections.
  • Use variables and authentication without sharing secrets.
  • Write assertions and request-workflow scripts.
  • Exercise normal, invalid, and unauthorized API cases.
  • Export documented collections and evaluate supported automation options.

Pre-requisites

  • Familiarity with HTTP, REST, and JSON.
  • Basic JavaScript is helpful for scripts and assertions.
  • No previous Postman experience is required.

Lab Setup

  • Supported Postman application or browser/agent setup verified before the course.
  • Local sample API, synthetic users, dummy tokens, and collection fixtures.
  • Confirm current account, plan, export, and CLI requirements in advance; use no confidential workspaces or production credentials.

Detailed Course Outline

API Request Fundamentals

  • Methods, URLs, headers, and payloads
  • Status codes and response interpretation
  • JSON bodies and content types
  • Distinguishing API contracts from interface behavior

Collections and Workspaces

  • Organizing folders and requests
  • Naming and documenting request intent
  • Imports and portable collection exports
  • Account, sharing, and plan boundaries

Variables and Environments

  • Variable scopes and resolution
  • Environment-specific base URLs
  • Data-driven request inputs
  • Keeping tokens and secrets out of shared exports

Authentication and Access Cases

  • Basic, bearer, and OAuth concepts
  • Supplying dummy test identities
  • Testing unauthorized and forbidden operations
  • Separating identity checks from business permissions

Scripts and Assertions

  • Pre-request and post-response scripts
  • Status, header, and body assertions
  • Schema checks and business-rule checks
  • Recording failures with useful evidence

Collection Workflows

  • Chaining requests through response values
  • Setup and cleanup responsibilities
  • Repeated requests and duplicate effects
  • Collection runner and test-data files

Documentation and Automation

  • Examples and API documentation
  • Mock-server and specification-import concepts
  • Current Postman CLI/Newman compatibility and account requirements
  • CI reports and portable local alternatives

Practical Exercise

  • Build a collection for a local create/read/update API
  • Test valid, malformed, unauthorized, and repeated requests
  • Parameterize the environment and exclude dummy secrets from exports
  • Produce collection files, execution results, and cleanup instructions
