External Form Connector questions

Hello everyone,

I have two questions on Form Connectors that I'm looking for some information on.

1. When using the REST api code from the final step of the external form connector wizard, the code provided is a GET url as it includes variables for the fields in the URL path. Is there a way to POST to the api url for the RESTform.aspx?

2. The REST api code doesn't have any information on authentication, is there anything needed around authentication, the REST api code does have a variable for customer number, my assumption is that is sufficient and there isn't any other authentication requirements needed.

Kind regards

Justin
