Did you enter “name” into the field name when creating the field? If so then it should load, but I’m a bit confused at what you’re trying to do. If you change the field name then acf will not be able to load the values in the WP admin.
You would be better off just naming the fields what they need to be named in order to send it to the 3rd party. Either that or use an acf/save_post filter to get the values after they are submitted, convert the field names and send the data to the 3rd party.
