POST/v2/invoices/:id/checkout

Create a checkout session

This endpoint creates a checkout sessions for a pending invoice.

A practical example:

  1. You first create an invoice via the the create an invoice endpoint
  2. Then generate a checkout session via this endpoint.
  3. Finally, you retrieve the payment_url you receive in the response, and show this to your customer as a button, or redirect them to the respective URL.

If the invoice is priced as zero, which means it's a free product, the invoice will instead be marked as completed.

See the code examples for how to create a new invoice payment URL with the SellApp API.

PATCH/v2/invoices/:id/mark-completed

This endpoint allows you to update a pending invoice's status as completed. If marked as completed, the purchased product(s) would be delivered to the customer's email. See the code examples for how to mark a pending invoice as completed with the SellApp API.

PATCH/v2/invoices/:id/issue-replacement

Issue replacement for completed invoice

In the event you want to replace the deliverables of an invoice, this endpoint lets you do so.

When you send a request to the endpoint, behind the scenes a new invoice gets created and immediately marked as completed. From there, the regular flow proceeds with a customer receiving a delivery email with a link to access their products, and you receiving a sales notification.

See the code examples for how to issue a replacement product for an existing invoice with the SellApp API.

Required attributes

  • Name
    product_variants
    Type
    array
    Description

    Array of associated product variant ID('s) to be replaced.

    Make sure to pass along the product variant ID(s), not the product ID(s)
