    We have been working on a project for quite a while. We had to take some of it step by step, but I am pleased that we are getting closer to what I want.

    Volker 2 says,

    This project involved updating the online payment functionality of a website which has been continuously online for the past 19 years. The first online payment functionality were "PayPal Payment Buttons" to which "Stripe Card payments" were added when Stripe only supported credit/debit cards over 5 years ago. Arcmax now implemented Stripe v3 payments which include a PayPal option. While this is tricky (Stripe needs adjustments for additional payment options), he sorted it out and implemented that newer payment gate on three websites. This included another option where a string of up to 450 characters has to be transmitted to Stripe in order to process that information and make it available in email messages to both seller and buyer. This is now also working perfectly.
