Hi Juan , i hope you are doing great ,Unfortunately i paused this feature in my project ! your suggestion is a good idea , i think it is similar to other services where you ask people for a permission to connect their social media accounts such as "Pinterest , Buffer…etc " , you may need to add API connector and know some skills to avoid any unsecure issues .
There is another unprofessional idea to make this feature such as let the supporters send you the money directly to your paypal account and add a notification for the creators that some one donate money for them , and at specific day at month you can send the money for them from your paypal account , but the challenge here is avoiding the transaction commission fees ,but you can make your users aware about transaction paypal commission.
- The plugin in general is a good one and you can subscribe and test it , It is only 5 $ a month .
Hopefully other support can help you more
