# News: New ID token verification endpoint released

New ID token verification endpoint released

When your back-end server receives an ID token originating from LINE Login v2.1 or the LINE SDK, you should verify that the ID token is authentic.

Previously, you had to use a JWT library (opens new window) or write your own decoding and verification code.

After this release, you merely have to send an HTTP request to the verification endpoint to determine if an ID token is authentic.
