With which status can I send my goods/deliver the service?
By default you can send goods or deliver your service once a transaction has reached the status "9 - Payment requested". However, although status 5 is a successful status, it's only a temporary reservation of an amount of money on the customer's card. A transaction in status 5 still needs to be confirmed (manually or automatically) to proceed to the status 9, which is the final successful status for most payment methods.
