}What is HTTP 201 Created?
HTTP 201 Created indicates that the request has been fulfilled and resulted in one or more new resources being created. This status code is typically sent in response to POST requests or some PUT requests that create new resources.
- Location Header: The response should include a Location header with the URI of the newly created resource
- POST Requests: Most commonly used when creating resources via POST
- Resource State: The resource has been successfully created and is available
- Response Body: May contain a representation of the newly created resource
When Does This Happen?
A 201 Created response is returned when a new resource has been successfully created. This is more specific than 200 OK and communicates the exact outcome. You'll see this status code when:
- Creating a new user account via a registration endpoint
- Submitting a form that creates a new database record
- Uploading a new file or document to a server
- Creating a new item in a RESTful API (e.g., POST /api/products)
- Any operation that results in a new resource being stored on the server

Common Use Cases
✅ Resource Creation Testing
Test how your application handles successful resource creation and processes the newly created resource data.
🔄 POST Request Testing
Mock successful POST responses in tests without needing to actually create resources in a database.
🎨 Frontend Development
Develop and test UI flows for creating new items before the backend creation logic is implemented.
📝 API Documentation
Provide working examples of resource creation endpoints in API documentation.
🧪 Integration Testing
Simulate resource creation scenarios in integration tests without side effects.
🔍 Status Code Validation
Verify that your application correctly distinguishes between 200 OK and 201 Created responses.
