Okay thank you!

This means that to sell, my members must have a Business account with #PayPal. Okay. Next, we have Identity Token and and Sandbox. You have said that Sandbox is a testing environment, so this can be left blank... I have a small UNA site and I want to go live right away, I will leave Sandbox blank/empty.

Now, the entire question comes down to this....and this is what EVERYONE setting up #Market and #Payments app need to know. It all comes down to the Identity Token. How do we get an Identity Token?

I have a #PayPal Business account. I have access to Developer pages. 

Here are some pages that may be involved, but they do not show an Identity Token:

https://developer.paypal.com/docs/business/accept-payments/

https://developer.paypal.com/docs/api/overview/

https://developer.paypal.com/developer/applications

I found something called BrainTree on one of those pages, and it allows to create an Access Token that starts with something like: access_token$production$.......  Is this the correct token?

Do you have any more information on how to obtain an Identity Token?

Thank you very much, UNA Themes
