unable to automate the execution of the acitvity step in user decision step

Hi,

I am able to automate the workflow process by capturing the WI ID of the user decision step and passing it in WAPi DECISION COMPLTE and redirect to the approve path of the decision by passing user decision as 0001

But I am unable to execute the activity step in the approve path of the user decision...

Is there a way to automatically execute the approve activity step or do I have to go to SBWP and execute the approve activity of the user decision step manually?

Regards
