If you’re new to Unstructured, read this note first.

Before you can create a source connector, you must first sign up for Unstructured. After you sign up, the Unstructured user interface (UI) appears, which you use to create the 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, reach out to the community on Slack, or contact us directly.

You are now ready to start creating a source connector! Keep reading to learn how.

Ingest your files into Unstructured from Google Cloud Storage.

The requirements are as follows.

  • A Google Cloud service account. Create a service account.

  • A service account key for the service account. See Create a service account key in Create and delete service account keys.

    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 service account 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", "")

  • The URI for a Google Cloud Storage bucket. This URI consists of the target bucket name, plus any target folder within the bucket, expressed as gs://<bucket-name>[/folder-name]. Create a bucket.

    This bucket must have, at minimum, one of the following roles applied to the target Google Cloud service account:

    • Storage Object Viewer for bucket read access.
    • Storage Object Creator for bucket write access.
    • The Storage Object Admin role provides read and write access, plus access to additional bucket operations.

    To apply one of these roles to a service account for a bucket, see Add a principal to a bucket-level policy in Set and manage IAM policies on buckets.

To create the source connector:

  1. On the sidebar, click Connectors.
  2. Click Sources.
  3. Cick New or Create Connector.
  4. Give the connector some unique Name.
  5. In the Provider area, click Google GCS.
  6. Click Continue.
  7. Follow the on-screen instructions to fill in the fields as described later on this page.
  8. Click Save and Test.

Fill in the following fields:

  • Name (required): A unique name for this connector.
  • Bucket URI (required): The URI for the Google Cloud Storage bucket and any target folder path within the bucket. This URI takes the format gs://<bucket-name>[/folder-name].
  • Recursive (source connector only): Check this box to ingest data recursively from any subfolders, starting from the path specified by Bucket URI.
  • Service Account Key (required): The contents of a service account key file, expressed as a single string without line breaks, for a Google Cloud service account that has the required access permissions to the bucket.
