If you’re new to Unstructured, read this note first.Before you can create a source connector, you must first sign in to your Unstructured account:After you sign in, the Unstructured user interface (UI) appears, which you use to get your Unstructured API key, as follows:
  1. After you sign in to your Unstructured Starter account, click API Keys on the sidebar.
     For a Team or Enterprise account, before you click API Keys, make sure you have selected the organizational workspace you want to create an API key for. Each API key works with one and only one organizational workspace. Learn more.
  2. Click Generate API Key.
  3. Follow the on-screen instructions to finish generating the key.
  4. Click the Copy icon next to your new key to add the key to your system’s clipboard. If you lose this key, simply return and click the Copy icon again.
After you create the source connector, add it along with a destination connector to a workflow. Then run the worklow as a job. To learn how, try out the hands-on Workflow Endpoint quickstart, go directly to the quickstart notebook, or watch the two 4-minute video tutorials for the Unstructured Python SDK.You can also create source connectors with the Unstructured user interface (UI). Learn how.If you need help, email Unstructured Support at support@unstructured.io.You are now ready to start creating a source connector! Keep reading to learn how.
Ingest your files into Unstructured from Google Drive. The requirements are as follows.
  • A Google Cloud account.
  • The Google Drive API enabled in the account. Learn how.
  • Within the account, a Google Cloud service account and its related credentials.json key file or its contents in JSON format. Create a service account. Create credentials for a service account. To ensure maximum compatibility across Unstructured service offerings, you should give the service account key information to Unstructured as a single-line string that contains the contents of the downloaded service account key file (and not the service account key file itself). To print this single-line string without line breaks, suitable for copying, you can run one of the following commands from your Terminal or Command Prompt. In this command, replace <path-to-downloaded-key-file> with the path to the credentials.json key file that you downloaded by following the preceding instructions.
    • For macOS or Linux: 
      tr -d '\n' < <path-to-downloaded-key-file>
    • For Windows: 
      (Get-Content -Path "<path-to-downloaded-key-file>" -Raw).Replace("`r`n", "").Replace("`n", "")
  • A Google Drive shared folder or shared drive.
  • Give the service account access to the shared folder or shared drive. To do this, share the folder or drive with the service account’s email address. Learn how. Learn more.
  • Get the shared folder’s ID or shared drive’s ID. This is a part of the URL for your Google Drive shared folder or shared drive, represented in the following URL as {folder_id}: https://drive.google.com/drive/folders/{folder-id}.

Document permissions metadata

The source connector outputs any permissions information that it can find in the source location about the processed source documents and associates that information with each corresponding element that is generated. This permissions information is output into the permissions_data field, which is within the data_source field under the element’s metadata field. This information lists the users or groups, if any, that have permissions to read, update, or delete the element’s associated source document. The following example shows what the output looks like. Ellipses indicate content that has been omitted from this example for brevity.

To look up information about a particular Google Cloud user, use the user’s ID along with the Admin SDK API or the People API for Google Cloud. To look up information about a particular Google Cloud group, use the group’s ID along with the Admin SDK API or the Cloud Identity API for Google Cloud. To create a Google Drive source connector, see the following examples. 
import os

from unstructured_client import UnstructuredClient
from unstructured_client.models.operations import CreateSourceRequest
from unstructured_client.models.shared import CreateSourceConnector

with UnstructuredClient(api_key_auth=os.getenv("UNSTRUCTURED_API_KEY")) as client:
    response = client.sources.create_source(
        request=CreateSourceRequest(
            create_source_connector=CreateSourceConnector(
                name="<name>",
                type="google_drive",
                config={
                    "drive_id": "<drive-id>",
                    "service_account_key": "<service-account-key>",
                    "extensions": [
                        "<extension>",
                        "<extension>"
                    ],
                    "recursive": <True|False>
                }
            )
        )
    )

    print(response.source_connector_information)
Replace the preceding placeholders as follows:
  • <name> (required) - A unique name for this connector.
  • <drive-id> - The ID for the target Google Drive folder or drive.
  • <service-account-key> - The contents of the credentials.json key file as a single-line string.
  • For extensions, set one or more <extension> values (such as pdf or docx) to process files with only those extensions. The default is to include all extensions.
    Do not include the leading dot in the file extensions. For example, use pdf or docx instead of .pdf or .docx.
  • Set recursive to true to recursively process data from subfolders within the target folder or drive. The default is false if not otherwise specified.
