Salesforce limits the number of API calls that can be made to an org. It would be nice if the Domo integration included a name as part of their API calls so Salesforce Admins could understand how refresh rates impact API usage.
Implementation is done through a CallOptions.client value that can be passed as part of the SOAP call, or as a header in the REST API. This allows the API usage Last 7 Days report to show usage for Domo vs a rolled up number for the login id (and prevents the need to allocate a VERY EXPENSIVE single purpose user for domo).
