## Introduction

Horus is an accounting software based on new technologies, designed with and for digital technology. It simplifies your work considerably, you save time on a daily basis and you follow your figures in real time. Deliver the Horus integration your customers want in no time.

## Configure Horus

**Prerequisite(s)**

* ️ obtain a “Client ID” and “Client Secret”
* ️ get an OAuth2 application for your partner account.
* Activate the Horus integration on the Chift platform.

**Activation Process**

* send an email to [developer@horus-software.be](mailto:developer@horus-software.be) to ask for your Client ID and Client Secret that will be used for all your customers. Provide the following information when requesting the Client ID and Client Secret:
  * name of the integration
  * contact person & email address
  * short description of how (= using Chift) and why you intend to use the API
  * redirect Url: [https://chift.app/oauth2/redirect](https://chift.app/oauth2/redirect)

## Test Horus

To test the software integration, ask Chift to contact and request Horus for a sandbox account on your behalf.

## Connect Horus

To activate a connection with Horus, users will have to go through the following steps.

* French article: [Help Center - Horus FR](https://help.chift.app/articles/2823105645-horus?lang=fr)
* English article: [Help Center - Horus EN](https://help.chift.app/articles/2823105645-horus?lang=en)
