I have an instance of MS Project Server version 16.0.4327 and I am trying to use the REST API to delete tasks because the SOAP API is unavailable on this version.
What I'm doing is:
Check-out the project
Send a delete task request
Wait for an empty queue
Publish the changes
Check-in the project
The problem is that all of the delete task API calls don't seem to do anything even though they return HTTP 200 OK. I tried to use the /task('taskId')/deleteObject() call described here: https://msdn.microsoft.com/en-us/library/office/jj668556.aspx
and I tried to send a POST request with "DELETE" in the X-HTTP-HEADER to this url
