I'm making progress in learning to use the rest API (HTTP web service) in SPD.
WF1: Acivates to a change to a list. WF1 is suppose to launch WF2 using the Rest API. Within WF1 I have the WF2 GUID and the list ID where the change occured.
WF2: At the moment, just logs to workflow history.
The request header:
Accept : application/json;odata=verbose Content-Type : application/json;odata=verbose
The response code = OK, but the WF is not launching. Does the X-RequestDigest need to be populated for the POST to work?
Note - I'm not doing any coding. Trying to keep this OOTB.
