Customer Portal: Deep link `Change Plan` & `Cancel` & Order Details/Benefits

[birkjernstrom]

Few sellers have requested the ability to easily deep link their customers to the customer portal and for the Change plan-modal to appear immediately, cancel or viewing the order and associated benefits.

So that they can link to these in their own Change or Cancel actions easily within their own service without too much integration work on performing those actions on their own end.

Ideally, this should likely be part of the Customer Session API to generated a presigned (authenticated) redirect. Being able to pass it details on how to deep link. For instance:

{
   "subscription_id": "<id>",
   "order_id": "<id>",
   "action": "change|cancel"
}

In case subscription_id or order_id is given it defaults to the overview of those. Unless action is specified which deep links further by opening up those modals.
