Attached is a data flow that demonstrates how to use the REST API in Data360 Analyze.
Before you can do anything via the REST API you'll need to get a login token, instructions on how to obtain one can be gotten here: Login Token
Note: tokens only last for four hours at most, so you will need to keep getting a new one if needs be.
Data360 Analyze has robust documentation on the REST API, which can be found in the 'System administration' > 'API developer' documentation topic of the integrated Help for your Analyze instance.
Note: You may wish to use the Analyze CLI in preference to the API for a set of simple use cases. See article here: Data360 Analyze: AnalyzeCLI
