Help me API crypto payment gateway

[thinkingforward1990]

Hi all members,
I'm the owner a web shop selling online game accounts. Currently, I want to integrate crypto payments at my store online.
Hope you can share to me some payment services that provide API for crypto payment gateway (Not direct to page 3rd party like coinpayments or coinbase...)
Thanks and Best Regards

Doesn't Coinbase commerce provide an API which you can use directly without referring the user to the invoice page though?

What CMS did you use with your online shop?
BTCpayserver supports multiple CMS check here
If you don't want to use 3rd parties then you need to deploy this in your own node/server. Raspberry pi is the best option if you already have but you can deploy this on VPS.
