API Reference

An API reference is a detailed, technical guide that lists and explains all available endpoints, methods, parameters, and data structures provided by an API. It serves as a go-to resource for developers to understand exactly how to interact with the API programmatically.

Key components of an API reference include:

  • Endpoint URLs: The paths used to access specific API functions

  • HTTP Methods: The actions supported (e.g., GET, POST, PUT, DELETE)

  • Request Parameters: Query strings, headers, path variables, and body inputs

  • Response Format: The structure and content of the response (usually JSON or XML)

  • Status Codes: HTTP status codes with their meanings (e.g., 200 OK, 400 Bad Request)

  • Authentication Requirements: API key or token usage details

  • Error Codes & Messages: Specific codes returned in case of failures

  • Examples: Sample requests and responses to guide implementation

An API reference is typically auto-generated or maintained as part of the API documentation and is intended for developers to integrate and troubleshoot with precision.
