Google Drive Queue

Note: For general information about Queue Steps, see Queue Step.

Google Drive is a personal cloud storage service from Google that allows you to store and synchronize digital content across computers, laptops and mobile devices, including Android-powered tablets and smart phone devices. Once permissions are granted by the owner of a Google Drive account, the component facilitates uploading or downloading files to the account.

Google Drive Queue Property Descriptions

Property	Description
Token Folder	Local directory that will be used to store an OAuth token after the owner of the Google Drive account has granted the requested permissions to the component. Click Browse and select a folder. You can also right-click and use the Paste Macro option to specify the token folder. After specifying this folder, you must test the connection and obtain a valid token for connecting to Google Drive. For the steps, see Obtaining Valid Token for Connecting to Google Drive. The connection is successful if a valid token file is created in the Token Folder.
Test Connect Timeout	Maximum amount of time in seconds before "Test Connection" will time out. The default value is: 60
Delete Uploaded Files When Finished	When set to TRUE, all the uploaded files are automatically deleted after the process completes. The default value is: FALSE

Obtaining Valid Token for Connecting to Google Drive

The Test Connection option helps you to obtain a valid token for connecting to Google drive.

To test the connection and obtain a valid token, perform the following:

1. In the Google Drive queue component properties, in the Token Folder, specify a path. This is the folder where the granted OAuth token file will be created. For example, C:\Temp.

2. Click Test Connection.

The Google Sign in page opens with the following message:

Choose an account to continue to Actian DataConnect

3. Select your Google or Gmail account that you want to connect with Actian DataConnect.

The Grant Actian DataConnect permission dialog is displayed asking for permission to view, edit, create, and delete all of your Google Drive files.

4. Click Allow.

The following message is displayed:

View and manage metadata of files in your Google Drive files

5. Click Allow.

The following message is displayed:

Confirm your choices

6. Click Allow.

The following message is displayed:

Received verification code

7. Click OK and then click Save.

The Google Drive Queue component is ready to use.

8. Open file explorer and go to the folder that you had specified as the Token Folder. You will see a new file called StoredCredential is created. This is the granted token file for your Google Drive account.

Override Queue Properties

You can override the values provided for the object name and local file name in the PutMessage action using the following DJMessage properties:
