Mockbin is a hosted service for creating custom endpoint for testing HTTP requests. The service generates an endpoint based on your specified criteria then allows any online service to hit that endpoint and receive a pre-defined response.
A new "bin" can be created without an account or login which makes setup quick and easy. Each new bin can be created with custom response codes, headers, cookies, and body.
Endpoints are easy to use (and easy to share) with the provided URL generated by the creation process. Once created a response preview is provided along with implementation examples in multiple programming languages.
Each endpoint, or bin, also retains a history, listing each request with the request method, size, and requesting IP Address as well as the specific request details.
