Multi Channel Pinpoint Journey

Hi,

I want to be able to contact users via Email and SMS when a specific event is triggered.

My understanding is that I need to define 2 endpoints for the user, one with his Email and one with his phone number and link them via the UserId. I guess there isn't any way to add 2 different channels to the same endpoint?

What I tried:

• I created 2 endpoints: One for Email (user1-email), one for SMS (user1-sms) with the same UserId (user1).

• I created 2 dynamic segments: one for channel=EMAIL, one for channel=SMS

• I created a Journey with an event as entry: event=delivery

• I added a "Multivariate Split":

  • Segment "Email" => Send Email
  • Segment "SMS" => Send SMS

• When sending the event=delivery to Pinpoint for the endpoint user1-email, the email is delivered as expected

• When sending the event=delivery to Pinpoint for the endpoint user1-sms, no SMS is sent, but the email flow is executed and sent to the address attached to user1-email

• Adding user2-sms (SMS channel) with no linked email channel:

  • When sending the event=delivery to Pinpoint for the endpoint user2-sms, the SMS is successfully delivered (meaning there isn't any SMS configuration mistake)

Am I doing something wrong or is this the intended behavior? I find it very odd that information from the endpoint user1-email would be used when the event is sent to the endpoint user1-sms, unless we have a way to define "preferred channel for a user".

Is there another way to achieve this that doesn't involve calling send-message for each destination from a Lambda function?

Thanks,

Daniel
