I recieved an e-mail regarding SCA after a payment test in live mode.
Mail content from Stripe was like below:
Thank you for choosing Stripe! We’re writing because we noticed your account is impacted by a regulatory requirement called Strong Customer Authentication (SCA). SCA requires two-factor authentication on many payments in Europe. Payments that are not authenticated are at risk of being declined by your customers’ banks.
Your account has payments (like this one) in live mode using the Charges API, which does not support the authentication requirements of SCA. We recommend using one of our SCA-ready integration paths to avoid more declined European payments.
After this e-mail I reached out to Stripe support team and I got this answer from them:
(01:01:38 AM) Efren: Yeah, SCA authentication is not working on your Stripe account.
(01:01:44 AM) Efren: I wish I could be of a bit more help here, but since WCMP built their integration with Stripe, they’ll be best able to help you with this directly.
