How can I send the products info to own API?

Hi everyone, I’m new to Shopify and I want to know how I can get the product data in the checkout section and send it to my own external API. I know how to program in JS and React, but I don’t know how to use Shopify or GraphQL functions. Can someone help me please?

Hey Jair3008,
You can try Shopify pixel. Thanks!
