Permissions for service accounts

Certain permissions and roles are required for the service account.
For more information, refer to GCP - Introduction to IAM.

Service account for Source config

We recommend that you create a service account where the Validio platform is granted access to the GCS bucket you want to read data from.

The following roles must be assigned to the service account:

  • storage.buckets.get
  • storage.objects.get
  • storage.objects.list

Service account key

  • Obtain a service account key in JSON file format for your service account.
    For details, refer to Create and delete service account keys.
  • Provide the service account to the Credentials field in Validio by either:
    • Upload the JSON file to the JSON file field.
    • Paste the content of the JSON file into the JSON text field.
