get_plan(plan_id)

Gets a plan with a given identifier

grant_for_guard(arg1, guard)

Returns a payment record which grants access to the payment guard. Default behaviour filters where remaining_usages is greater than 0 or has a nil value (unlimited usage). You can also provide a list of grants in place of the first parameter in order to avoid a trip to the database.

grants_for_shop(shop)

Returns a list of valid grants which are associated with the store.

list_available_plans_for_guard(shop, guard)

Get a list of plans for shop based on provided guard

use_grant(shop, grant)

Updates the grant to reflect the usage of it in some way. Defaults to decrementing the remaining_usages property if it's not nil. If it is nil, the grant has unlimited usages
