To avoid problems, I advise not to sell this theme to clients from Brazil.

Hi Rosana Fernandes. Good afternoon!

Thank you for contacting PayPal! My name is Evellyn Cristina and I will help you with your request for APP ID
Regarding APP ID, this is an integration that is not available in Brazil. If you use your site will not work and this is not what we want.

The site was all set up, depending only on APP ID.
And now how are we? Already wasted time translating and changing the site, now I have financial loss ??
