- After sign in, a new session is created by issuing a refresh and access token to the frontend.
- The frontend sends the access token for each API call that requires session authentication.
- These API calls verify the access token and its expiry. If verification fails, the API throws a session expired error, else, execution continues.
- If an API throws session expired error, the frontend uses its refresh token to get a new refresh and a new access token. This is done via a special API on your backend. If a session has been revoked, this API will also throw session expired after which the user will have to login again.
- After obtaining a new set of tokens, the frontend retries the original API call, yielding the desired result.
- To revoke a session, the backend removes the refresh token and its session information from its database.
