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
• Scroll down and create a new production env (it takes a few minutes to create one)
• Once the production env is created, you can find your SMS API key under the setup section:

2) Set the SMS API key in the backend SDK config

NodeJS

Important

For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.
