Class Method Details

.activate(shop, charge) ⇒ Object

Synchronises the status of a given charge from the Shopify API and returns true if it’s active (and false otherwise).

Previously, the activation of a charge also required updating Shopify via the API, but that requirement has been removed.

See shopify.dev/changelog/auto-activation-of-charges-and-subscriptions
