On Google Cloud Platform (GCP), the account-level Databricks Terraform Provider or account API does not use standard Databricks tokens or standard Databricks OAuth. Instead, it relies on Google Cloud ID (OIDC) tokens generated via a Google Cloud service account.

provider "databricks" {
  alias                  = "accounts"
  host                   = "https://accounts.gcp.databricks.com"
  account_id             = var.databricks_account_id
  google_service_account = var.databricks_google_service_account
}

resource "databricks_mws_vpc_endpoint" "backend_rest_vpce" {
    provider = databricks.accounts
    account_id = var.databricks_account_id
    vpc_endpoint_name = "vpce-backend-rest-ven"
    gcp_vpc_endpoint_info {
        project_id = var.network_project_id
        psc_endpoint_name = var.backend_rest_psce
        endpoint_region = google_compute_subnetwork.network-with-private-secondary-ip-ranges.region
    }
}
