Method 3) SuperTokens SMS service

Using this method, SuperTokens will send SMSs to your users automatically. Use this method if:

You are already using our managed service - this is the quickest way to setup SMS sending.
You want to take advantage of some of the SMS sending optimisations we add over time:
- Reduce SMS cost by picking a local SMS service based on the destination country.
- Fight spam / misuse of SMS.

important

This is a paid service and we charge for every SMS based on the cost we incur. We give new users $10 worth of credits.

1) Get the SMS API key#

Sign up on supertokens.com
Create a new development env
