Greetings, @CG70 .

Thank you for reaching out and posting this question!

You can change your credit card payment provider directly in the Shopify admin, located under the Payment settings (‘Settings > Payments’). However, since it looks like you’re staying with the same provider, then you may need to deactivate your existing payment provider and reactivate it using your new gateway and ID number.

I can see that you are a new member of our Shopify Community! Once you’ve updated your payment provider credentials, I’d love to hear more about your business and share some resources to help you get started. What kinds of products are you selling? Does your store have a marketing plan in place?
