I run a website and accept payments thru API. I upgraded the API to the latest version and ever since then some of my customers go to submit payment on their invoice and they get an error saying “payment failed”. Some of my other customers are able to make a payment but some aren’t. Any idea what it could be? Maybe should I revert back to an older version of the API? Any help would be appreciated.

Hey there @maple7789! 
Are you getting these errors with the Invoices API? Do you mind letting me know what your app ID is?
