Introduction to the Invoicing Service API
Important: The NVP/SOAP integration method for Invoicing is Deprecated. For new integrations, see the REST Invoicing Overview.
PayPal enables you to create and manage invoices. When you send an invoice, PayPal emails the receipient and allows him or her to pay with PayPal.
The following diagram shows the basic execution flow for creating and sending an invoice:

When your customer clicks Pay Invoice in the email, the customer's browser is redirected to PayPal and the customer is prompted to log in.
The customer can then pay on PayPal.
The contents of an invoice depend on what you specify in the
CreateAndSend requests. Following is an example invoice:
Sending Invoices on Behalf of a Merchant
You can send invoices on behalf of a merchant if you have permission to do so. There is no difference in how you set up your request for
CreateAndSendInvoice, except that you specify the merchant's email address instead of your own in the request, and you include an additional header that indicates you have the permission of the third party to send invoices on their behalf.
The merchant grants you permission using their PayPal profile, or you request permission using the Permissions Service API. For more information about this API, see PayPal Permissions Service at PayPal Permissions Service.
Invoicing Service API Operations
The operations in the Invoicing Service API enable you to create and send invoices to your customers, as well manage existing invoices, which may or may not have been sent.
Note: You must have a valid app ID to use the Invoicing Service API. If you have an existing app ID, you can reuse it. For more information, see Creating and Managing NVP/SOAP API Credentials.
