Use the request method attributes

Each request attribute takes a URL:

<button hx-post="/tasks">Create task</button>
<button hx-patch="/tasks/42">Complete task</button>
<button hx-delete="/tasks/42">Delete task</button>

Use the HTTP method to describe the operation:

• hx-get retrieves a representation without changing server state
• hx-post commonly creates a resource or performs a command
• hx-put replaces a resource representation
• hx-patch applies a partial change
• hx-delete removes a resource

The attribute only declares a request. The server still needs a matching route, authentication, authorization, validation, and CSRF protection for state-changing methods.

HTMX 2 sends values for DELETE in URL parameters by default, aligning it with the current specification behavior. Do not assume the request body format from an older HTMX version; inspect the actual request and configure your server parser accordingly.

GET must remain safe because browsers, crawlers, caches, and prefetchers may repeat it. A route that deletes on hx-get is dangerous even if the current button is the only visible way to call it.

Open the Network panel and verify method, URL, and parameter location for each example.

Use GET for safe retrieval. Use a state-changing method for create, update, or delete actions.
