Login

Present client credentials to obtain an authorization token

Looker API implements the OAuth2 Resource Owner Password Credentials Grant pattern. The client credentials required for this login must be obtained by creating an API key on a user account in the Looker Admin console. The API key consists of a public client_id and a private client_secret .

The access token returned by login must be used in the HTTP Authorization header of subsequent API requests, like this:

 Authorization: token 4QDkCyCtZzYgj4C2p2cj3csJH7zqS5RzKs2kTnG4 

Replace "4QDkCy..." with the access_token value returned by login . The word token is a string literal and must be included exactly as shown.

Example of passing credentials in the HTTP request body:

 POST HTTP /login
Content-Type: application/x-www-form-urlencoded

client_id=CGc9B7v7J48dQSJvxxx&client_secret=nNVS9cSS3xNpSC9JdsBvvvvv 

NOTICE

Pass 'client_id' and 'client_secret' as body parameters.

The ability to use query parameters for client_id and client_secret will be deprecated before the end of 2026.
