Hi, I have activated both PayPal and Stripe for use by my customers on my website.  I have tried to add Stripe as a payment provider in accounting but keep getting an error message. I have raised an inquiry but have not received a way to resolve it. 
Is it really this difficult to add on a payment method? Please help!

PS I have looked at all of the courses and I can't see anywhere where it outlines how to add payment methods.
