Cards rejected by Stripe are accepted by PayPal
In the last 2 weeks, we're encountering too many unsuccessful transactions from the Indian, Mexican users. The same cards are going through Paypal smoothly. Is your business having similar trouble accepting payments through Stripe? How are you making sure the transactions go through from different regions?
Are you using the older (and simpler) synchronous "Charges" Stripe API? Many non-US payments require a text message for verification by the card holder. Using the asynchronous "Payment Intents" stuff should fix that. I recently switched, and it dramatically improved the charge success rate for non-US customers.
Hm! Stripe may have (mistakenly?) flagged them for fraud. Could you email me details of those charges at edwin@stripe.com and I can double check?
