Workflow command '' is not valid

[HATETHISS]

Hi all,

I'm trying to execute a workflow via the REST API. First I call the GET method that returns the trigger URL. Then I call this url via POST method but I receive the following error: 

RST-360011 An error has occurred - please contact your administrator.
Workflow command '' is not valid
Error while executing the method 'ProcessCommand' of service 'xtk:workflow'.

I couldn't find any information regarding this issue.

Many thanks

Hi,

Adobe Campaign Classic doesn't ship with a REST API or an xtk:workflow#ProcessCommand action.

Maybe custom development? GET method that returns trigger URL?

Thanks,
