We’re happy to announce the full release of the Shopify Billing API.
Shopify Apps are now able to issue one-time and monthly recurring charges (i.e. subscription plans) through the API, which means that features like tiered plans, coupon codes, trial periods, and much more are easily doable.
Invoicing and collection of application charges and plan upgrading/downgrading are all handled by Shopify – there’s no complex billing code for you as a developer to deal with or have to write yourself.
If you’d like to know more, documentation and a tutorial on how to use the new billing API features are available with the Shopify API docs.
