I think you can find more information in Message Queue API with examples. you can have a look at that and see if you can find something.
Please post here the call which you are trying.
Hi Sai Prasad,
Thanks for your reply!
Unfortunately there is nothing about Deleting records in the "Message Queue Based Communication-v7-20200812_023019.pdf" which I received from Support earlier.
Neither is there any info/example on Creating Single Tasks by the way.
Hence, there is not a call that I can post now, since it really does not fit any wsdl operation.
