Hi there @Viorica_Marga
yes it is possible, I am pretty sure studio also does the same thing when used as an activity.,
As of now I dont have a workflow but using the API is shown here in detail About OData and References
and check this thread on how to use it and what not to do after you get your token - Authenticate fails for Orchestrator API - #12 by loginerror
May I ask why you want API through code rather than a simple activity?
Regards
