API Plus
Build a fully customised lending experience where customers see offers from within your platform
Build a fully customised lending experience where customers see iwoca's offers in your platform. API Plus gives you maximum control over the customer journey, up to the point they select an offer. It often delivers higher conversion than our other integration options.
Prerequisites
Before you begin, make sure you have:
- Access to our Partner Developer Portal, where you can get your API token for the sandbox environment.
Don't have access? Chat with your Partnership Manager to gain access to the Partner Developer Portal.
Integration steps
Building the customer-facing screens? See our UX guidance for screen-by-screen direction on the customer and application forms, what to show and hide on the offers screen, offer hierarchy, button behaviour per offer type, and decision outcomes.
