Certain credentials and permission are required for Validio to validate your data:

A service account with access and permissions to the specified GCS bucket.
A JSON file containing the service account key.

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.
