# Getting started

> Get started using the Creditor API

Welcome! This guide will help you quickly get up and running with the Debbie Creditor API.

## 1. Get access to the creditor portal

Your debt collection partner will invite you to the creditor portal. If you do not have access yet, please reach out to them.

## 2. Create an API key

In the creditor portal, navigate to the Developer section in the menu. From there, you can create a new API key and select the scopes it should have access to.

<Warning>
  The API key is only shown once, when it is created. Store it in a safe place.
</Warning>

On the same page you will find your `tenantId` and `creditorId`. You will need both when calling the API — the `tenantId` is part of every URL, and the `creditorId` identifies you as the creditor.

## 3. Understand the core concepts

Before diving into the endpoints, we recommend reading the Core Concepts section to familiarize yourself with how customers, cases and case vouchers fit together.

## 4. Build your integration

For a typical ERP integration you only need two endpoints:

1. [Create customer](/api-reference/endpoints/customers/create) — create the customer with the debtor's contact details.
2. [Add case vouchers](/api-reference/endpoints/customers/add-case-vouchers) — send the unpaid invoices and fees for collection.

The platform automatically determines when to create a new case or update an existing one.
