Recurring payments are not supported globally yet. For example, a German customer cannot use PayPal to make RPs.

Except if the company is applying at PayPal and is large enough (e.g. Twitch; German users can indeed subscribe to channels), because PayPal is basically granting the account owner (company) the right to just deduct money from the donator. And for this they need to trust the company.

Source: We called PayPal support last friday because we tried to make RPs work with German customers in one of our projects, but had to cancel that plan because we are not a large enough company (i.e. we didn't even apply for this kind-of secret treatment).
