Smartrr
Smartrr is a subscription and loyalty platform for Shopify DTC brands. It adds subscribe-and-save subscriptions, a branded customer account portal, loyalty and rewards, referrals, bundles, and retention tooling on top of Shopify. Its Vendor API (https://api.smartrr.com) lets merchants programmatically manage the subscriptions their customers hold - modeled as "purchase states" - along with the subscribers, orders, bills, and the selling plans / subscription programs products are sold on. The API is authenticated with a per-organization access token generated in the Smartrr admin Integrations tab and sent in the x-smartrr-access-token header. A full OpenAPI document (116 operations) is served publicly at https://api.smartrr.com/docs/spec.json and rendered at https://api.smartrr.com/docs/redoc/.
Smartrr publishes 6 APIs on the APIs.io network, including Bills API, Orders API, Plans API, and 3 more. Tagged areas include Subscription, Loyalty, Shopify, E-Commerce, and Direct to Consumer.
Smartrr’s developer surface includes authentication, documentation, API reference, and 7 more developer resources.
