AuthorizationResponse

AuthorizationResponse: CancelledResponse | AuthorizationSuccessResponse

The response object of requestAuthorization. Either the user cancelled the flow or they successfully gave authorization.

AuthorizationSuccessResponse

AuthorizationSuccessResponse: {data: {accessToken: string;grantedScopes: string[];serverAuthCode: string | null; };type: "success"; }

An object that contains an access token that has access to the grantedScopes. It contains also the serverAuthCode if offlineAccess was requested.

On iOS, you can also obtain serverAuthCode by calling createAccount() with offlineAccess: true.

Type declaration

data	{accessToken: string;grantedScopes: string[];serverAuthCode: string | null; }
data.accessToken	string
data.grantedScopes	string[]

OneTapConfigureParams

OneTapConfigureParams: ClientIdOrPlistPath & {hostedDomain: string;logLevel: "debug" | "info" | "warn";offlineAccess: boolean;openIdRealm: string;profileImageSize: number;scopes: string[];webClientId: WebClientId; }

webClientId is the most important parameter in the configuration. It is required.

Type declaration

Name	Type	Description
hostedDomain?	string	iOS only. Specifies a hosted domain restriction. By setting this, authorization will be restricted to accounts of the user in the specified domain.
logLevel?	"debug" | "info" | "warn"	Web only. Controls debug logging in browser console. This is implemented in Google's web SDK and is not part of their public API so it may change or be removed at any time.
offlineAccess?	boolean	iOS only. Use requestAuthorization on Android. Must be true if you wish to access user APIs on behalf of the user from your own server. When offline access is requested, an authorization code is returned so the server can use the authorization code to exchange for a refresh token. The refresh token allows the server to access Google data on behalf of the user. Default false

profileImageSize?	number	iOS only. The desired height and width of the profile image. Default 120px
scopes?	string[]	iOS only. The Google API scopes to request access to. Use requestAuthorization to request additional scopes on Android. Default ["email", "profile"]

Functions

isCancelledResponse()

isCancelledResponse(response: OneTapResponse): response is CancelledResponse

TypeScript helper to check if a response is a cancelled response. This is the same as checking if the response.type === "cancelled".

Use this if you prefer to use a function instead of comparing with a raw string.

It supports both One Tap and Original Google Sign In responses.

Parameters

Parameter	Type
response	OneTapResponse

Returns

response is CancelledResponse

Example

const response = await GoogleOneTapSignIn.createAccount();

if (isCancelledResponse(response)) {
  // handle cancelled response
}

Parameter	Type
error	any

Returns

error is NativeModuleError

---

isNoSavedCredentialFoundResponse()

isNoSavedCredentialFoundResponse(response: OneTapResponse): response is NoSavedCredentialFound

Use this if you prefer to use a function instead of comparing with a raw string.

It supports both One Tap and Original Google Sign In responses.

Parameters

Parameter	Type
response	OneTapResponse

Returns

response is NoSavedCredentialFound

Example

const response = await GoogleOneTapSignIn.signIn();

if (isNoSavedCredentialFoundResponse(response)) {
  // the case when no user was previously signed in
}

isSuccessResponse()

isSuccessResponse(response: OneTapResponse): response is OneTapSuccessResponse

CancelledResponse

CancelledResponse: {data: null;type: "cancelled"; }

The response object when the user cancels the flow for any operation that requires user interaction.

On the web, this is also returned while cooldown period is active. Detecting the cooldown period itself is not possible on the web for user privacy reasons. On Android, it can be detected via ONE_TAP_START_FAILED

data	null
type	"cancelled"

---

ClientIdOrPlistPath

ClientIdOrPlistPath: {iosClientId: string; } | {googleServicePlistPath: string; }

You can specify a different bundle path for the config file, e.g. "GoogleService-Info-Staging".

Alternatively, set the client ID explicitly by providing iosClientId.

Web Modern sign in module

WebOneTapSignInCallbacks

WebOneTapSignInCallbacks: {momentListener: MomentListener;onError: (error: NativeModuleError) => void | Promise<void>;onResponse: (userInfo: OneTapExplicitSignInResponse) => void | Promise<void>; }

When using Modern sign in on the web, the sign in result is delivered via a callback, not via a promise. The shape of data delivered to the callback is the same as the shape of the data in the promise, enabling code reuse. Read more in the guide.

Type declaration

Name	Type	Description
momentListener?	MomentListener	A callback function that is called when important events take place. See reference.
onError	(error: NativeModuleError) => void | Promise<void>	Called when an error occurs. You can use the code property of the error to determine the reason for the error. The reported errors on the web are in the same format as the errors reported on the native platforms, so you can reuse your error handling code.
onResponse	(userInfo: OneTapExplicitSignInResponse) => void | Promise<void>	Called when the user successfully signs in, or cancels the sign in, either using the web One-tap flow or the button flow.
