Answer 1

It's unfortunate that I didn't come across this question earlier, but I will provide all the most relevant information in case someone has the same question in the future.

To make a data transfer with the Admin SDK Data Transfer API we will use 2-3 methods from 2 different APIs:

• Users.get [Admin SDK Directory API] (https://developers.google.com/admin-sdk/directory/reference/rest/v1/users/get) to obtain the userID required for the oldOwnerUserId and newOwnerUserId parameters in the next Transfers.insert API call.
• Transfers.insert [Admin SDK Data Transfer API] (https://developers.google.com/admin-sdk/data-transfer/reference/rest/v1/transfers/insert) to create the data transfer.
• Applications.list [Admin SDK Data Transfer API] (https://developers.google.com/admin-sdk/data-transfer/reference/rest/v1/applications/list) to list supported applications by the Data Transfer API.

Note: you may use the API explorer available in the documentation of the API to test the output and parameters of the API before you implement them into a solution. Keep in mind that all actions taken in the API Explorer will have real consequences in your domain. It is highly suggested you experiment with test accounts before you affect users in production.

I will now provide a sort of pseudocode that shows the flow of data and API calls your application will make:

1. Obtain the userId of the source and destination of the data transfer with Users.get, using these parameters:

"userKey": "user@domain.com",
"fields": "primaryEmail,id"

Will result in this server response:

{
  "id": "108020532870171195535",
  "primaryEmail": "user@domain.com"
}

You will run this twice to obtain both oldOwnerUserId and the newOwnerUserId values we will use to construct the data transfer in the next call.

2. Call the Transfers.insert method with the following request body:

{
  "oldOwnerUserId": "#####################",
  "newOwnerUserId": "#####################",
  "applicationDataTransfers": [
    {
      "applicationId": 55656082996,
      "applicationTransferParams": [
        {
          "key": "PRIVACY_LEVEL",
          "value": [
            "SHARED",
            "PRIVATE"
          ]
        }
      ]
    },
    {
      "applicationId": 810260081642,
      "applicationTransferParams": [
        {
          "key": "PRIVACY_LEVEL",
          "value": [
            "SHARED",
            "PRIVATE"
          ]
        }
      ]
    }
  ]
}

In my example the data transfer created transfers data from applicationId: 55656082996 (Google Drive) & applicationId: 810260081642 (Google Data Studio). These are not the only supported Google services, you can find the rest by calling the Applications.list method.

At this time the Data Transfer API supports transferring data from the following services between users in the same organization:

• Google Currents (553547912911)
• Google Calendar (435070579839)
• Google Data Studio (810260081642)
• Drive and Docs (55656082996)

In case you are wondering, other types of data can be transferred between Google Workspace users as outlined in this Help Center article https://support.google.com/a/answer/1041297.
