HTTP Methods and Status Codes:
<ul>
<li>GET: Retrieve information from the server (e.g., read a resource).
</li>
<li>POST: Send data to the server to create a new resource.
</li>
<li>PUT: Update an existing resource on the server.
</li>
<li>DELETE: Remove a resource from the server.
</li>
<li>Status Codes:
<ul>
<li>200 OK: Successful GET, PUT, DELETE, or POST.
</li>
<li>201 Created: Successful POST that results in a new resource.
</li>
<li>204 No Content: Successful request that doesn’t return a body.
</li>
<li>400 Bad Request: Client-side error.
</li>
<li>404 Not Found: Resource not found.
</li>
<li>500 Internal Server Error: Server-side error.
</li>
</ul>
</li>
</ul>
Designing Resource URIs:
<ul>
<li>Use nouns to represent resources (e.g., <code>/users</code>, <code>/orders</code>).
</li>
<li>Use sub-resources for relations (e.g., <code>/users/{id}/orders</code>).
</li>
<li>Be consistent in URI design (e.g., use hyphens or underscores).
</li>
</ul>
