# Quickstart

### Overview

This guide provides a step-by-step approach for initiating and managing a loan application using the Partner API. Before you begin, please review the Realfinity Resources to understand how [Clients](/api/api-reference/clients.md) and [Loan Applications](/api/api-reference/loan-applications.md) interact.

### Prerequisites

To access the Partner API, you must have a Client Id and Client Secret. If you do not possess these, please contact your account executive or support team.

### 1. Generate an OAuth Token

Use the `/oauth/token` endpoint with your Realfinity-provided `client_id` and `client_secret` to generate an OAuth token. This token is crucial for future API requests.

### 2. Creating a Client

Use the `/clients` endpoint to create a Client. This is an essential first step, as Clients form the base to which multiple loan applications can be linked.

### 3. Starting a Loan Application

To begin a loan application with the `/loan-applications` endpoint, ensure a Client is created.
