This is a sample API Flow that can be imported into ION Desk. The flow first calls a customer API in Infor CloudSuite Financials, then uses the output of that API to call an Amazon S3 API to get data from a file in a S3 bucket. The results of both API calls are combined into one response.
Unzip the file, import the .xml file contained within into the API Flow modeler tool in ION Desk.
