If you need to print an invoice for payments you can use our account system.
Register at our accounts website. Use the same email address you used to register on the API, we advise that you update all your accounts to use the same email address to ensure you only have one login for this site.
You can add your company information which will be added to the invoice.
Under each marketplace click on transactions where you can view all previous payments for the API account.
