Connecting to GoogleTasks

To authenticate to GoogleTasks, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

Using OAuth Authentication

You must create a custom OAuth application to connect to Google Tasks. To create a custom OAuth application:

Log into the Google API Console
Create a new project or select an existing project
Navigate to the "Library" section and enable the Google Tasks API
Navigate to the "Credentials" section and click "Create Credentials" > "OAuth client ID"
Select "Desktop application" or "Web application" depending on your use case
For web applications, add your callback URL to "Authorized redirect URIs"
Note down the Client ID and Client Secret

After setting the following connection properties, you are ready to connect:

AuthScheme: Set this to OAuth.
InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
OAuthClientId: Set this to the client_id that is specified in your app settings.
OAuthClientSecret: Set this to the client_secret that is specified in your app settings.
CallbackURL: Set this to the redirect URI you specified in your app settings.

Example connection string:

Profile=C:\profiles\GoogleTasks.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;
