NAME
    gcloud auth application-default print-access-token - print an access token
        for your current Application Default Credentials

SYNOPSIS
    gcloud auth application-default print-access-token
        [--scopes=SCOPE,[SCOPE,...]] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    gcloud auth application-default print-access-token generates and prints an
    access token for the current Application Default Credential (ADC). The ADC
    (https://google.aip.dev/auth/4110) can be specified either by using gcloud
    auth application-default login, gcloud auth login
    --cred-file=/path/to/cred/file --update-adc, or by setting the
    GOOGLE_APPLICATION_CREDENTIALS environment variable.

    The access token generated by gcloud auth application-default
    print-access-token is useful for manually testing APIs via curl or similar
    tools.

    In order to print details of the access token, such as the associated
    account and the token's expiration time in seconds, run:

        $ curl -H "Content-Type: application/x-www-form-urlencoded" \
        -d "access_token=$(gcloud auth application-default print-access-token)" \
        https://www.googleapis.com/oauth2/v1/tokeninfo

    Note that token itself may not be enough to access some services. If you
    use the token with curl or similar tools, you may see permission errors
    similar to "Your application has authenticated using end user credentials
    from the Google Cloud SDK or Google Cloud Shell". If it happens, you may
    need to provide a quota project in the "X-Goog-User-Project" header. For
    example,

        $ curl -H "X-Goog-User-Project: your-project" \
            -H \
            "Authorization: Bearer $(gcloud auth application-default \
         print-access-token)" foo.googleapis.com

    The identity that granted the token must have the serviceusage.services.use
    permission on the provided project. See
    https://cloud.google.com/apis/docs/system-parameters for more information.

FLAGS
     --scopes=SCOPE,[SCOPE,...]
        The scopes to authorize for. This flag is supported for user accounts

        For end-user accounts, the provided scopes must be from ['openid',
        'https://www.googleapis.com/auth/userinfo.email',
        'https://www.googleapis.com/auth/cloud-platform'], or the scopes
        previously specified through gcloud auth application-default login
        --scopes.
