Code for third party payment

Hi,
I am working on my website and I am trying to link my merch account for payments that is not available on Wix. I know that I have to use a JavaScript code. Can someone help me to find that code.
Thanks

Are you looking for the full code?

This forum is not for the do-it-for-you code.

Please check the velo examples related to 3rd party API integration: https://www.wix.com/velo/examples?category=integrations

Then, read the API docs from the payment provider to integrate with your Wix Stores.

Make use of Wix Stores module.

Advanced coding knowledge required.
