Learn to use Postman to send http requests for api interactions, performing create, read, update, delete operations with parameters, headers, authorization, body data, and understand request structure and responses.

Master sending http requests in Postman, including get, put, post, patch, and delete, with authentication, url and query parameters, body options, header presets, code snippets, and the Postman console.

Explore how Postman handles request authentication to secure API endpoints, covering no authentication, API keys, token-based and bearer token authentication, basic and digest, with parent-level inheritance.

Explore how the parameters tab handles query parameters for filtering, sorting, and pagination, use URL parameters and path variables, bulk edit key-value pairs, and automatic URL encoding in Postman.

Learn how to send request bodies in Postman using form data, urlencoded, raw (json, html, xml, text), binary, and GraphQL, with put operation example to update a course by id.

Explore request header presets in Postman by grouping headers and reusing them across requests, including an example of setting API version to 2.0 for getting a course item.

Postman's code snippets generate ready-to-use client code for the current request in multiple languages, such as C-sharp, speeding API integration. It also offers language-specific settings that update the generated code.

Explore how the Postman console captures request and response details, enables filtered troubleshooting, and distinguishes console logs from history for effective API debugging.

Master advanced http requests in Postman by applying authentication, configuring parameters and body types (json, form data, graphql), and generating code snippets with troubleshooting via the console.

Learn how to organize Postman API requests by creating and managing collections and folders, including saving, adding, and editing requests, and understanding collection types and uses.

Explore how Postman collections organize saved requests into folders, enable logical grouping, collaboration, API documentation, and streamlined API testing for efficient workflow.

Discover three ways to create a Postman collection—via the collections tab, the new button, or the workspace overview—and learn to manage collection details, scripts, variables, and sharing links.

Learn how to add a request to a collection in Postman, save existing or history requests, and organize them under eCampusConnect with folders like students and student ID.

Edit an existing collection via the three-dot menu to adjust names, authorization, variables, and pre-request and test scripts, then document details with markdown and manage folders, favorites, and workspace moves.

Postman collections organize saved requests into folders, enable collaboration, API testing, and collection-level documentation; create collections in three ways, save existing requests, add new ones, and rename or delete.

Explore how Postman uses variables and environments to store and reuse values, group them into collections, and manage global versus environment scope for efficient API testing.

Discover how Postman variables store and reuse values to avoid hardcoding, reducing errors across requests. Understand dynamic values and variable scopes—local, environment, and global—to control when and where values apply.

Group related variables into environments to simplify managing api requests across development, testing, and production contexts. Enable context switching and controlled access for sensitive tokens while keeping variables organized.

Create and manage environments in Postman by adding variables, duplicating existing setups, and selecting a current active environment to auto-retain across sessions.

Create and manage environment variables in Postman, using a base url and port for all requests, and understand initial versus current values and how exporting shares only initial values.

discover how global variables in postman work across the current workspace and collections, differ from environment variables, and how to create and reference a version in requests.

Learn how to manage Postman environments across workspaces by sharing, moving, renaming, and deleting, including options to duplicate or remove environments and considerations for monitors and mock servers.

Learn to use Postman environments by defining variables including local, environment, and global, and switch values across contexts. Manage environments by creating, saving, sharing, duplicating, and deleting.

Explore how to group Postman elements into workspaces by using collections, environments, variables, and visibility settings, and learn to create, manage, and share workspaces for team collaboration.

Explore workspaces in Postman, learn their purpose, and see how they group APIs, collections, environments, mock servers, and monitors to enable parallel and collaborative work.

Explore how visibility of workspace controls who can access API elements including APIs, collections, environments, monitors, and mock servers, and learn when to use personal, team, private, or public settings.

Create a Postman workspace via the new button or workspaces menu, name it, set visibility, and define it before use as the root for collections and APIs.
