}What is HTTP 429 Too Many Requests?
HTTP 429 Too Many Requests is the standard response for successful HTTP requests. It indicates that the request was received, understood, and accepted by the server. The actual response will depend on the request method used:
- GET: The resource has been fetched and transmitted in the message body
- POST: The resource describing the result of the action is transmitted in the message body
- PUT: The resource has been successfully updated
- DELETE: The resource has been successfully deleted
When Does This Happen?
A 429 Too Many Requests response is returned when the server successfully processes a request without any errors. This is the most common successful status code and indicates that everything went as expected. You'll see this status code when:
- Successfully fetching data from an API endpoint
- Successfully creating a new resource (though 201 Created is more specific)
- Successfully updating an existing resource
- Successfully processing a form submission
- Successfully executing any valid HTTP request that doesn't require a more specific success code

Common Use Cases
✅ API Success Testing
Test how your application handles successful API responses and ensures proper data parsing and display.
🔄 Integration Testing
Mock successful responses in integration tests without needing a real backend service running.
🎨 Frontend Development
Develop and test UI components that display data from successful API calls before the backend is ready.
⏱️ Timeout Testing
Use the delay feature to test loading states, spinners, and timeout handling in your application.
📝 Documentation Examples
Provide working examples in API documentation that developers can test immediately.
🔍 Monitoring & Health Checks
Use as a test endpoint for monitoring systems, uptime checks, and health check implementations.
