API diagrams
We have several different RESTful API endpoints that you can use.
How to use the diagrams
In each diagram, navigate from the central bubble that is the base endpoint, then to the method (GET, POST, PUT, and DELETE), and then to any additional path parameters.
Each of the connections also has a short description of the operation.
However, some operations just use the base endpoint. For those, the method is given and then a pointer to a blank path parameter, which is meant to indicate that you do not add anything else for the described operation. These also have a parenthetical attached that gives the name of the operation as specified in the API.
