}What is HTTP 204 No Content?
HTTP 204 No Content indicates that the server successfully processed the request, but is not returning any content. The response may include headers but has no message body. This is commonly used for actions that don't require a response body.
- No Response Body: The server doesn't send any content in the response
- Successful Operation: The request was processed successfully
- DELETE Requests: Commonly used for successful DELETE operations
- Headers Only: May include response headers without body content
When Does This Happen?
A 204 No Content response is returned when the server successfully processes a request but doesn't need to return any content. You'll see this status code when:
- Successfully deleting a resource (DELETE requests)
- Successfully updating a resource without returning the updated data
- Saving user preferences or settings
- Acknowledging actions that don't require a response
- Handling form submissions that don't need confirmation data

Common Use Cases
🗑️ DELETE Operations
Test deletion operations that return no content upon success.
💾 Silent Updates
Mock update operations that don't need to return the updated resource.
⚙️ Settings & Preferences
Simulate saving configuration changes without response bodies.
✓ Acknowledgments
Test scenarios where the server just acknowledges an action.
🔄 Polling Endpoints
Mock polling endpoints that return 204 when no new data is available.
📝 Form Submissions
Handle form submissions that don't require confirmation data in response.
