Getting provider's access token

You can get the Third Party Provider's access token to query their APIs with the following method:

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.
