Add/Update Subscription

The following endpoint can be used to add or update a Subscription within the Hyfin application. When a Subscription is added to Hyfin, a request will be automatically generated and the customer will be notified via text message, email or both based on the notification options set on the customer record. After submitting their payment method, the customer will automatically be charged based on the frequency of the recurring payment.

If the customer is viewing the Subscription on their device and it gets updated, a message will display letting the customer know the Subscription has been updated and the new version of the Subscription will automatically be displayed on the customers device.

Once the customer has accepted the Subscription, the record will become unable to be modified unless it is to close the Subscription.
