ViewsAWS SNS with FMC for SMS
I am developing a React native application where I want to sent an SMS for OTP. I used AWS SNS for publishing messages after subscribing them to a topic, but I found that the price is quite high since the SMS is transactional.
I wanted to use Firebase Messaging Cloud since they do it for free but I don't really know how to proceed with it. Do I have to createPlatformApplication and then do createPlatformEndpoint for every user to send messages? This is a bit confusing for me, so if someone could give me an overview of the initial processes, it would do me wonders.
This is how I am doing it now simply using subscribe and publish:

I understood your question as asking how you could deliver OTP codes using push notifications.
To do that, you would:
- Set up a platform application through SNS: https://docs.aws.amazon.com/sns/latest/dg/mobile-push-send-register.html
- Create an endpoint for each end device you want to send these notifications to: https://docs.aws.amazon.com/sns/latest/dg/mobile-platform-endpoint.html
- Do a direct publish to that endpoint to send the notification only to that person: https://docs.aws.amazon.com/sns/latest/dg/mobile-push-send-directmobile.html
For this use case, you do not need to use topics and subscriptions, since all of your messages will only be targeting one person.
