LoanPro API Introduction

The comprehensive API reference for LoanPro's Loan Management System.

Built on REST principles, our API accepts JSON payloads and returns JSON responses along with standard HTTP response codes. Our platform provides users with a Production environment and a separate Sandbox environment for testing. Each environment uses its own set of authentication tokens.


LoanPro offers APIs for two different applications.

The docs you're looking at now are for the Loan Management System (LMS). We also have docs for our Secure Payments API—an application that integrates with multiple payment processors and securely stores payment information.

To see the documentation for Secure Payments, simply switch from Version 1 (v1.0) to Version 1.1 (v1.1) in the drop-down menu at the top of the page.


Our docs are listed in a particular order. We have organized each section to follow what we call the "loan lifecycle":

  • Customers
  • Loans
  • Loan Servicing
  • Payments
  • Charges
  • Loan Grouping
  • Reports

We find that this is the most natural flow to a loan's life, and it helps ensure each step is completed properly. After these main sections, you will find Account-Level Settings and requests involving Entities.

If you can't find a specific request, try using the search bar at the top of the page.
