General
We currently integrate with Shopify, WooCommerce, Bigcommerce and Stripe’s Relay API (not Stripe’s standard subscriptions API). From time-to-time, we might consider integrations with other Ecommerce platforms too.
Yes, we do have an API, but it doesn’t currently support all of Conversio’s Premium functionality. We are planning to update this in future. Until then, we do not recommend using this.
