@spec create_or_update(Moov.Client.t(), String.t(), map()) ::
  {:ok, map()} | {:error, Moov.Error.t()}

Creates or updates underwriting details for an account. This is the preferred entry point - update/3 (PUT) is being sunset in favor of calling this repeatedly as details change.

params typically includes :average_transaction_amount, :max_transaction_amount, :volume_by_customer_type, :average_monthly_transaction_volume, :volume_by_payment_type, :cards_volume_5_percent_or_more and similar fields - see the Moov dashboard's underwriting requirements for the exact set for your account type.

@spec get(Moov.Client.t(), String.t()) :: {:ok, map()} | {:error, Moov.Error.t()}

Retrieves underwriting details for an account.

@spec update(Moov.Client.t(), String.t(), map()) ::
  {:ok, map()} | {:error, Moov.Error.t()}

Updates underwriting details via PUT.
