Merchants

WeGetFinancing lets your customers pay over time at checkout. A complete integration has two parts: the checkout integration — offering WeGetFinancing as a payment option and turning approvals into orders — and the on-site promotion that helps shoppers discover financing before they reach the cart.

Ways to integrate

Pick the method that fits your platform and how much control you need — from a ready-made plugin to a full API integration.

• E-commerce plugin — the easiest path when your platform is supported. Install the plugin for Shopify — or see the full list, including WooCommerce, Adobe Commerce (Magento), and BigCommerce — and configure it in your store admin. Little or no code required.
• Merchant API — the most robust and flexible option, for custom or self-developed carts. Your server creates a financing request, shows the application, and receives the decision by postback — a deep integration with your checkout and order-tracking flow. Start with the Merchant API reference or the backend integration guide.
• Link integration — the quickest, no-code path for hosted platforms you can’t modify, for brick-and-mortar, or for call centers. Add a link (or send an application to a customer) that opens the WeGetFinancing application. See Link Integration.
• PPE widget — the Purchase Power Estimator shows an estimated monthly payment on product and cart pages, so shoppers see financing options before checkout. It pairs with any of the methods above. See the PPE widget.

How the checkout flow works

Whichever method you choose, the core flow is the same:

1. Create a financing request with the customer and cart details. You get back a customer-facing application URL and an order token.
2. The customer completes the application — shown in a lightbox on your site, or by redirect.
3. You receive the decision as a postback. Create the order only when the decision is approved — never on the browser callback alone.

The Merchant API reference documents the request fields, the lightbox, and the postback contract in full.

Before you start

Set up your account in the WeGetFinancing back-office: configure your lenders, loan programs, and integration type, and get your API credentials under Integration → API Integration. Every integration has a sandbox and a production environment with separate credentials — build and test against sandbox first, then switch to production. See Test Environment & Data to get started, and Branding & Guidelines for assets to promote financing on your site.
