REST API Cheat Sheet

REST API principles

What this cheat sheet is for

This rest api reference helps you complete common developer tasks quickly and avoid repeated trial-and-error when working under deadlines.

When you need a reliable command or pattern during debugging and incident response.
When you are implementing a feature and want a known-good syntax example immediately.
When onboarding teammates and documenting repeatable workflows for daily use.
When reviewing pull requests and verifying that command usage follows best practices.

REST Principles

Stateless, client-server, cacheable, uniform interface.

Resource Naming

GET /users          # List users
GET /users/1        # Get user
POST /users         # Create user
PUT /users/1        # Update user
DELETE /users/1     # Delete user

HTTP Methods

Use appropriate HTTP verbs for operations.

Status Codes

Return meaningful status codes.

Common mistakes / Pitfalls

People often copy a command or pattern without adapting placeholders, which can break production workflows unexpectedly.
It is easy to forget environment-specific differences, so always verify behavior in your shell, runtime, or API gateway before shipping.
Many errors come from skipping small validation steps, so test with realistic sample input before relying on the result.
