Networks drop, servers crash, and requests are malformed. Robust clients handle errors gracefully instead of crashing.</p> <h2 id="http-status-code-ranges">HTTP Status Code Ranges</h2> <ul> <li><strong>2xx</strong> - success. 200 OK, 201 Created, 202 Accepted, 204 No Content.</li> <li><strong>3xx</strong> - redirection. Follow Location headers when appropriate.</li> <li><strong>4xx</strong> - client error. The request is wrong; do not blindly retry without fixing it.</li> <li><strong>5xx</strong> - server error. Transient; safe to retry with backoff.</li> </ul> <h2 id="parsing-error-bodies">Parsing Error Bodies</h2> <p>Most REST APIs return a JSON error object with <code>code</code>, <code>message</code>, and often <code>details</code> or <code>param</code>. Parse these to surface actionable messages to users. Map provider error codes to your application&rsquo;s error vocabulary.</p>
