Accept Blue: Allow subscription cancellation

[martijnvdbrug]

Is your feature request related to a problem? Please describe.
We would like to be able to cancel created Accept Blue subscriptions, but there is no endpoint for that.

Describe the solution you'd like
An order line could have multiple subscriptions created in Accept Blue, but from a client perspective this shouldn't matter, so we would like to refund subscriptions referenced by order line ID:

    deactivateAcceptBlueSubscription(
      orderId: ID!
      orderLineId: ID!
    ): AcceptBlueSubscription!

• The accept blue service will get the created subscription IDS from the orderline, and cancel all subscriptions for that order line in Accept Blue.
• The order should not be cancelled, because it's the subscription that is being cancelled, not the order. Cancelling an order would mean the actual purchase never happened

We are still awaiting AC support to know how to cancel a subscription. De-active, or delete, or ?

By cancel we mean to end the repeating payments for that particular schedule. Wouldn't that be as simple as setting active=false for the schedule? We will also need to put a subscription "on hold" meaning we will suspend payments during a period - I would think the same method would apply but we would eventually change the active=true again for the "on hold" schedule. My question would be if we actually delete the schedule, do we lose the payment history etc that we need?

@is0utfitters Indeed, that's why deleting is not the prefered optioin. I wasn't sure if we could just pass active=false, because the sandbox env was using a different API call not available to us. But it turns out we can just deactivate:

I've also changed the mutation name to deactiveAcceptBlueSubscription to better reflect the action that its doing. This can indeed also be used to pause a subscription

I have question, how to handle Recurring paid?

1. if customer create a subscription paid monthly with intitial price $100
2. the second month, stripe will auto make payment for user with $100
3. should we make a webhook hook to handle Recurring paid events?

it seems that stripe subscription can not support this? e.g. we may need to run job to update somethings in vendure backend, (update licence period to next month)?

@tianyingchun This issue is about Accept Blue, but a short answer:

The Stripe Subscription plugin currently only creates the subscription in Stripe. This means the future payments you describe are handled by Stripe. Vendure only keeps track of the initial snapshot of the time of creating the subscription: the order itself.

I do agree that it would be nice to know in Vendure when future payments have been made. We did something similar in the Accept Blue plugin via webhook. Feel free to create a feature request (preferable with a PR 😄 ).
