If you use Shopify, then you don’t need to use our API, just install from the Shopify App Store. We are planning support for BigCommerce, Magento 2 and WooCommerce in 2021.
We also have an API which allows developers to upload your data to Machine Labs if you have your own custom platform or something that is not supported. It’s based on GraphQL and works great with any modern programming language.
At the moment the API is only available if you have over 10,000 contacts in your database. Contact us to arrange access.
The technical details are in the Developer Documentation.
