[Python] Boxtal API v3 – InvalidPaymentException (422) when creating shipping order from Odoo

I'm integrating Boxtal API v3 with Odoo to create shipping orders, but I’m getting the following error during the shipping order creation step:

{ "status": 422, "errors": [ { "code": "InvalidPaymentException" } ] }

My Boxtal account is active, and the API credentials are correct.

Does this error mean I need to set up a payment method or billing information on the Boxtal side before using the shipping API? Has anyone faced this before while working with Boxtal and Odoo?

Thanks in advance.
