Squarespace and Connecting Amex Direct Merchant ID number

Site URL: https://onyxhive.com.au

Hello,

Amex have contacted me regarding to help me grow my business, we do take payment for Amex through Stripe, the thing is, Amex created a merchant ID number for me and the payment needs to go through their payment gateway FIRST THEN stripe.

Right now the payment process for a customer is:

Add to cart > Pay through stripe integration with Amex > receive order

But what Amex told me what needs to happen is:
Add to cart > Pay through Amex payment gateway > Amex sends the fees to Stripe > Customer gets receipt

The workaround is for a customer makes a phone call and order through me and I make a manual payment through the Amex gateway manually.

I called stripe and they advised they can't implement this, can squarespace help me?

This isn’t possible to do on Squarespace or with Stripe. All payments through the Squarespace checkout must go through Stripe or PayPal. There are no alternatives; this cannot be achieved with code either.
