Buddypress member

Hi PayPal,

The members is buddypress register, login, member page, etc .

By just insert the [shortcode] on a create new page let’s say view picture/video, after the member paid and go back to the picture/video page, the [shortcode] button remain on the page?

For my understanding, how can this paypal payment go by each buddypress member? Does it have to do some kind of integration/migration to the buddypress member registration page, feature, etc?

Please advise help, thanks
