Add notification channels SmsPreferred and EmailPreferred

[acn-sbuad]

Description

Service owners may be flexible w.r.t which notification channel is used to pass on a notification. If this is the case they can prefer one channel, but be fine with the notification being sent via backup channel if required.

SmsPreferred will send an sms to the recipient if a mobile number is available, and an email if no mobile number is available, but an email address is.

Considerations

• If we cannot find neither an email address nor a mobile number should we create a notification within just the preferred notification channel which gets the status recipient not identified ?

  • Refinement: We will store the result on a notification on the preferred channel.

• Given a new notification channel, how do we ensure that service owners get the best view of the final result? We have the endpoints /notifications/sms and notifications/email but they would need to call both and cross check the lists to identify who has and has not received notifications.

  • Refinement: Deferred, we postpone this question to when we start getting questions or feature requests.

• How do we handle the case where notification channel is SmsPreferred and a recipient is provided with national identity number + an email address? Do we use provided email directly, look up sms and if no number present utse the registered or provided email ?

  • Refinement: Orders where a single recipient have both a lookup value and a specific contact point should be refused.

• When sending notification to org, if we find a set of emails for emailPreferred, do we not send sms to the users that only have a number registered? In other words, is emailPreferred evaluated for each eligible recipient, or for the organization as a whole?

Doing some initial testing and have found a small issue: Looks like we have a fallback to Email notification also when given channel is Sms. This is not expected. The expected result would be to fail with missing contact information.
