In anticipation of the new European legislation, we’ve just updated the official Stripe plugin to support Strong Customer Authentication (SCA), using Stripe’s new Checkout v3 integration. The new checkout flow is available on an opt-in basis: to enable it, just select “Checkout v3” from the Stripe checkout version dropdown in the plugin menu. Available actions have changed somewhat under v3: stored credit cards can no longer be used, and the checkout flow now provides you the opportunity to supply a product name, description, and image. If you don’t enable SCA, your app will be unaffected. You can read more about SCA in Stripe’s documentation.
Let us know if you have any problems!
