Glender — API Access

Introduction

The Glender API is a RESTful JSON API that lets brokers, lenders and technology partners programmatically access our property finance platform. Use it to fetch indicative rates, submit loan applications, check application status, query available lenders and register webhooks for real-time event notifications.

All API requests must be made over HTTPS to https://api.glender.io. Responses are returned in JSON format. The API follows standard HTTP status codes and includes detailed error messages.

Authentication

Authenticate every request by including your API key in the Authorization header. API keys are issued per-organisation and can be managed from your Glender dashboard.
