I am building a workflow that calls an external API using a custom Xtension.
While the API calls sent through Postman work as expected, the same calls through Nintex Workflow are met with the error:
Received an error response from the connector: Not allowed to execute the request for non permitted hosts.. [Error Code: IO.XtensionExecute.ErrorResponse]
Alternatively, I have tried using “Call a web service” action using the same API call. It also fails to get a response.
