Description
When a subscription is made in GoCardless, a specific amount is set up to recur automatically each month. However, if the cost of the service, and thus the invoice, changes, the subscription must be manually cancelled and re-created for the new amount. This is particularly troublesome when the cost of a service is changing frequently.
GoCardless appears to have an API command for updating the amount of a subscription:
https://developer.gocardless.com/api-reference/#subscriptions-update-a-subscription
Question is, what would be required to have the GoCardless gateway update a subscription when the amount changes?
