Designing RESTful Resource Endpoints

Use nouns for resources and standard HTTP verbs for state.

Use nouns for resources and standard HTTP verbs for state transitions. The examples separate the essential operation from the conditions a production implementation must enforce.

What It Does


Use nouns for resources and standard HTTP verbs for state transitions.

Prerequisites


Use a dedicated development environment with test accounts and records. Separate authorization, validation and error handling from response formatting; never copy demonstration-only secrets into production.

Example 1: Core Behavior


This scenario applies the exact rule described in the guide, with controlled sample values.

<?php
$method="GET"; $path="/items/12"; if($method==="GET"&&preg_match("#^/items/([0-9]+)$#",$path,$m)) echo "Read resource ".$m[1];

Example 2: Alternative or Failure Case


This scenario applies the exact rule described in the guide, with controlled sample values.

<?php
$method="DELETE"; $authorized=true; if(!$authorized){http_response_code(403);exit;} http_response_code(204); echo "Delete only after persistence succeeds";

Practical Example: Applying the Rule


This scenario applies the exact rule described in the guide, with controlled sample values.

<?php
$resource=["id"=>9,"url"=>"/items/9"]; header("Content-Type: application/json"); echo json_encode($resource);

Important Behavior and Edge Cases


HTTP method semantics, idempotency and error codes should remain consistent across resources.

Key Takeaways


  • Use nouns for resources and standard HTTP verbs for state transitions.
  • HTTP method semantics, idempotency and error codes should remain consistent across resources.
  • RPC-like action routes may suit workflows that are not naturally resources.

Select this API or pattern based on its documented behavior and the trust boundaries in your own application, and test all external integrations against their actual deployments.
