How to set a custom link to the "Buy Now" button?

Question

CMS

Good day. In connection with the law fz-54, the site was transferred to a robomarket (in order to save money on the purchase of cash registers).
The problem is that the client would go to the product card on the site and by clicking on the "Buy Now" button, he would be transferred to the robomarket to the same product card only with the possibility of online payment.
How can I implement individual links to the "Buy Now" button?

Answer 1

You can make products external. There is such an option. And put a link there. Better without programming.
You can add your own metafield Link and then, through hooks or template substitution, put it on the button.
