"SYNC"

, or

"ANY"

InvalidTokenDetails

Properties

  • token

    string

    The specific token that should be removed from the cache.

ProfileDetails

Chrome 84+

Properties

  • accountStatus

    AccountStatus optional

    A status of the primary account signed into a profile whose ProfileUserInfo should be returned. Defaults to SYNC account status.

ProfileUserInfo

Properties

  • email

    string

    An email address for the user account signed into the current profile. Empty if the user is not signed in or the identity.email manifest permission is not specified.

  • id

    string

    A unique identifier for the account. This ID will not change for the lifetime of the account. Empty if the user is not signed in or (in M41+) the identity.email manifest permission is not specified.

TokenDetails

Properties

  • account

    AccountInfo optional

    The account ID whose token should be returned. If not specified, the function will use an account from the Chrome profile: the Sync account if there is one, or otherwise the first Google web account.

  • enableGranularPermissions

    boolean optional

    Chrome 87+

    The enableGranularPermissions flag allows extensions to opt-in early to the granular permissions consent screen, in which requested permissions are granted or denied individually.

  • interactive

    boolean optional

    Fetching a token may require the user to sign-in to Chrome, or approve the application's requested scopes. If the interactive flag is true, getAuthToken will prompt the user as necessary. When the flag is false or omitted, getAuthToken will return failure any time a prompt would be required.

  • scopes

    string[] optional

    A list of OAuth2 scopes to request.

    When the scopes field is present, it overrides the list of scopes specified in manifest.json.

WebAuthFlowDetails

Properties

  • interactive

    boolean optional

    Whether to launch auth flow in interactive mode.

    Since some auth flows may immediately redirect to a result URL, launchWebAuthFlow hides its web view until the first navigation either redirects to the final URL, or finishes loading a page meant to be displayed.

    If the interactive flag is true, the window will be displayed when a page load completes. If the flag is false or omitted, launchWebAuthFlow will return with an error if the initial navigation does not complete the flow.

  • url

    string

    The URL that initiates the auth flow.

Methods

clearAllCachedAuthTokens

chrome.identity.clearAllCachedAuthTokens(
  callback: function,
)
Chrome 87+

Resets the state of the Identity API:

  • Removes all OAuth2 access tokens from the token cache
  • Removes user's account preferences
  • De-authorizes the user from all auth flows

Parameters

  • callback

    function

    The callback parameter looks like: () => void

getAccounts

chrome.identity.getAccounts(
  callback: function,
)

Retrieves a list of AccountInfo objects describing the accounts present on the profile.

getAccounts is only supported on dev channel.

Parameters

getAuthToken

chrome.identity.getAuthToken(
  details?: TokenDetails,
  callback?: function,
)

Gets an OAuth2 access token using the client ID and scopes specified in the oauth2 section of manifest.json.

The Identity API caches access tokens in memory, so it's ok to call getAuthToken non-interactively any time a token is required. The token cache automatically handles expiration.

For a good user experience it is important interactive token requests are initiated by UI in your app explaining what the authorization is for. Failing to do this will cause your users to get authorization requests, or Chrome sign in screens if they are not signed in, with with no context. In particular, do not use getAuthToken interactively when your app is first launched.

Parameters

  • details

    TokenDetails optional

    Token options.

  • callback

    function optional

    The callback parameter looks like: (token?: string, grantedScopes?: string[]) => void

    • token

      string optional

    • grantedScopes

      string[] optional

      Chrome 86+

getProfileUserInfo

chrome.identity.getProfileUserInfo(
  details?: ProfileDetails,
  callback: function,
)

Retrieves email address and obfuscated gaia id of the user signed into a profile.

Requires the identity.email manifest permission. Otherwise, returns an empty result.

This API is different from identity.getAccounts in two ways. The information returned is available offline, and it only applies to the primary account for the profile.

Parameters

getRedirectURL

chrome.identity.getRedirectURL(
  path?: string,
)

Generates a redirect URL to be used in launchWebAuthFlow.

The generated URLs match the pattern https://<app-id>.chromiumapp.org/*.

Parameters

  • path

    string optional

    The path appended to the end of the generated URL.

Returns

  • string

launchWebAuthFlow

chrome.identity.launchWebAuthFlow(
  details: WebAuthFlowDetails,
  callback: function,
)

Starts an auth flow at the specified URL.

This method enables auth flows with non-Google identity providers by launching a web view and navigating it to the first URL in the provider's auth flow. When the provider redirects to a URL matching the pattern https://<app-id>.chromiumapp.org/*, the window will close, and the final redirect URL will be passed to the callback function.

For a good user experience it is important interactive auth flows are initiated by UI in your app explaining what the authorization is for. Failing to do this will cause your users to get authorization requests with no context. In particular, do not launch an interactive auth flow when your app is first launched.

Parameters

  • WebAuth flow options.

  • callback

    function

    The callback parameter looks like: (responseUrl?: string) => void

    • responseUrl

      string optional

removeCachedAuthToken

chrome.identity.removeCachedAuthToken(
  details: InvalidTokenDetails,
  callback?: function,
)

Removes an OAuth2 access token from the Identity API's token cache.

If an access token is discovered to be invalid, it should be passed to removeCachedAuthToken to remove it from the cache. The app may then retrieve a fresh token with getAuthToken.

Parameters

  • Token information.

  • callback

    function optional

    The callback parameter looks like: () => void

Events

onSignInChanged

chrome.identity.onSignInChanged.addListener(
  callback: function,
)

Fired when signin state changes for an account on the user's profile.

Parameters

  • callback

    function

    The callback parameter looks like: (account: AccountInfo, signedIn: boolean) => void
