How do you do a POST from an External API Activity. It seems to only work for GET.
The answer above is not correct.
The activity also can do HTTP POST to web services.
You can try:
* Define any query (cannhave record count 0)
* Then define any field mapping in the outbound mapping
This then shall trigger a POST here
Yes it's only GET call. The External API activity brings data into the workflow from an external system via an HTTP API call.
