# GET /iid/info stops working

Calls to GET /iid/info/* on iid.googleapis.com stop working on September 29, 2027.

On September 29, 2027, the endpoint GET /iid/info/* will be decommissioned and calls to it will fail. This removal affects calls made to iid.googleapis.com under the InstanceId server APIs. After that day, requests to this endpoint will no longer work.

## What to use instead

To validate a token, call POST /v1/projects/{project}/messages:send on fcm.googleapis.com with validate_only set to true. To read a token's topics, switch to the FCM topic subscription API at /v1/projects/{project}/registrations/{registration}/topicSubscriptions.
