Create and Send Invoice

Creating and sending an invoice publishes a payable invoice that is automatically emailed to the customer. In addition to the sent email, you can also share the invoice by sending the customer the redirect URL generated in the invoiceInformation.paymentLink response field.

Itemized Invoices: An invoice can display a single billed amount or list up to 30 billed items. To list the billed items in the invoice, include the items in the request using the line item array fields. An invoice with line items is known as an itemized invoice.

Invoice Numbers: You can assign a unique invoice number in the invoiceInformation.invoiceNumber request field. The invoice number is required for follow-on API requests and tracking. You should store the invoice number in your system so that you can optimally perform the follow-on requests. If you do not include a unique invoice number when creating an invoice, generates a unique invoice number for you in the invoiceInformation.invoiceNumber response field.

Installment Payments: Invoices can be paid in installment payments when these fields and values are included in the request. If an invoice is payable in installments, multiple customers can make payments towards the same invoice.

Set invoiceInformation.allowPartialPayments to true.
Set orderInformation.amountDetails.minimumPartialAmount to the minimum amount allowed for a partial payment.

Partner Information: If your merchant account is associated with a partner, you can include your partner solution ID (PSID) in the request message for tracking and reporting purposes. To include your PSID, use the clientReferenceInformation.partner.solutionId request field and set its field value to your PSID.

A successfully created and sent invoice is indicated by the SENT status in the status response field. The response message also includes the newly created invoice's details.
