Comment to Cannot connect to Stripe payment
which API version are you using in stripe? (Check the stripe dashboard under developer) We use 2020-03-02 which is far from the latest, but it is the one that works without complaining. And we process a lot of payments.
Thx for your tip, @EducatedSingles . I tried it with the latest api version 2022-08-01 v1. Actually, I get some strange results when I chose a payment method in UNA 13-B4, as you can see in my comment.
