Imports an API definition file with details about an endpoint. Unlike Register an endpoint from an API definition file, this operation doesn't create a new endpoint, but updates details of an existing endpoint. You can run this operation in two ways. To POST JSON data, see Make a JSON request to edit an endpoint from an API definition file. To make a form request using these parameters, see Make a form request to edit an endpoint from an API definition file. Once you submit the POST request, to finish modifying the endpoint version, you need to take the response data and submit it as a request to the Edit a version operation.
