Do I need to subscribe to use an API-Compatible Character sheet?

I wish to use the Edge of the Empire sheet that is listed as "API Compatible". I understand I would have to be a mentor to modify the sheet - but will it work in my campaign if I don't subscribe? How can I tell if it is working properly? El Tea

Some character sheets utilize API scripts for the roll buttons. In order to make use of those buttons, the campaign needs to be running the requisite API script. In order to run any API scripts, the owner of the campaign must be a Mentor. If the owner is a Mentor, the players don't need to be. Alternatively, if you can live without the roll buttons doing anything useful, you can use the rest of the sheet without the API.

That is the best, most succinct and intellibible answer on this subject I have seen anywhere. Thank you.
