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 create your source connector.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 UI quickstart or watch the 4-minute video tutorial.You can also create source connectors with the Unstructured API. 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.
