US Patent 10133650 Automated API parameter resolution and validation

A method for automated application programming interface (API) validation includes extracting API information from an API repository. The API information is used to generate a test case for the automated API validation. The API information may include a parameter placeholder, parameter information related to a parameter of an API endpoint, an API endpoint of the API, an endpoint description, a description of the API, a description of the parameter, response information, an authentication requirement information, and an API name. The method includes resolving the parameter of the API endpoint. The method includes communicating to a native API system a request using the sample parameter value for the parameter. The method includes comparing a response from the native API system with the response information to validate the API. The method includes verifying integrity of a software application implementing the API endpoint for use with a native software application.
