I want to let users add their Stripe, Braintree or other payment processors API keys to my system and then let them send links to their clients where they can pay for services or whatever they are asking for.
Question is how much responsibility/liability I have taking into account I will only provide a system to connect their payment processor's accounts. I will never receive money from end-users. But domain, where they will be making payments, is mine.
Thank you for your help
