Welcome to the documentation for the Valar Operations API, here are some
quick tips if you just landed!
- The top level elements are the
Resources accessible via the API and the different queries used to
interact with each resource via the appropriate HTTP method call.
-
You can expand each method to get further information on the expected input
parameters and the different responses that can be received.
- For
both the input parameters and responses, an Example is present for
clarification.
- For further details, the example snipped can be
switched to Schema view, where a detailed explanation of each element
can be found.
- The Try it out button can be used to call the
API directly from the documentation page, which allows for some easy testing
and also provides the equivalent 'curl' command line code for easy
portability of the call execution.
- Before starting, remember
to use the token endpoint and activate the token with the Authorize
button.
