Main API Members
The list below outlines key members of the TdxGoogleAPIOAuth2AuthorizationAgent component. These members allow you to authorize your app in a Google account on behalf of a user and manage access tokens.
Access Token Management
- AccessToken | AccessTokenExpiresIn
- Return the current access token and its expiration time (in seconds).
- AccessTokenType
- Returns the access token type.
- DefaultTokenExpiresIn
- Specifies the default life time for an access token, in seconds.
- DefaultRedirectUri | RedirectUri | RedirectUriPort
Specify the address and port required to receive an access token.
Important
Use corresponding settings for different online service providers. Refer to the RedirectUri property description for detailed information.
- Load
Assigns specified access and refresh tokens.
Tip
This method is useful if you need to load existing tokens stored in the local file system.
- OnReceiveAccessToken | OnReceiveAuthorizationCode
- Allow you to override predefined authorization and authentication routines.
- RefreshAccessToken
- Refreshes the access token on demand using the refresh token.
- RefreshToken
- Returns the current refresh token.
- RevokeAccessToken
- Revokes the current access token. This operation also terminates the current authorization session.
- ValidateAccessToken
- Checks if the access token is valid and refreshes the token if it has expired.
Credentials Management
- ClientID
- Specifies a unique OAuth 2.0 client identifier.
- ClientSecret
Specifies the OAuth 2.0 secret for the identifier assigned to the ClientID property.
Important
We strongly recommend that you can handle the OnGetClientSecret event to request the client secret from a safe storage on demand.
- OnGetClientSecret
- Recommended. Allows you to load an OAuth 2.0 secret from a safe storage in response to starting an authorization session.

Permission Management

Google Cloud services require explicitly defined access scopes for authorization. If an associated data provider component requires a permission missing in AdditionalScopes, an authorization error occurs.

- RefreshScopes
- Reloads account access permissions.
Session Management
