## Introduction

Twinfield online accounting software easily manages all accounting functions, from invoicing to management accounting – for the smallest startup to the largest international group.

## Prerequisite(s)

To connect Twinfield with Chift, you need a certified Twinfield application.

<Warning>
  Twinfield’s certification costs €53 per month. This fee is billed directly by Twinfield and cannot be waived.
</Warning>

As a Chift customer, you benefit from a **custom and exclusive process** that gives you an **immediate and systematic certification** for your Twinfield connection.

* **No need for a Twinfield developer account.**
* **Your dedicated app is created by Chift in your name**, so your clients will see *your company name* (not Chift’s) during the OAuth2 authorization process.
* **No manual certification process required** if you’re a Chift customer.

All you need to do is complete the form shared by Chift. We handle app creation, technical validation, and provide access to the Twinfield test environment.

### Process

* **1. Contact your Chift Customer Success Manager**\
  Reach out to your CS Manager to start the certification process.\
  Chift will create your dedicated Twinfield app.
* **2. Complete Twinfield's client details form**\
  Fill in [Twinfield’s form](https://e.wolterskluwer.com/Aanvragen-API-Certificaat) with your company information, including billing details. You will need the `client_id` provided by Chift once your app has been created in step 1.

  <img src="https://mintcdn.com/chift/N835q-c27mfgQIFM/images/Twinfield-clientid-in-form.png?fit=max&auto=format&n=N835q-c27mfgQIFM&q=85&s=590f6f53c04b96d93e22a24443da50d5" alt="Twinfield Clientid In Form Pn" title="Twinfield Clientid In Form Pn" className="mx-auto" style={{ width:"53%" }} width="710" height="298" data-path="images/Twinfield-clientid-in-form.png" />
* **3. Access to the test environment**\
  Once the form is submitted, you will be provided with your test environment (and support portal). However, all support and guidance go through Chift—there’s no need to interact directly with Twinfield’s support portal.
* **4. Certification approval**\
  Once Twinfield processed your information, **your certification is granted immediately**.

## Test Twinfield

You will receive a testing environment right after the completion of step 2 of the process

## Connect Twinfield

To activate a connection with Twinfield, users will have to go through the following steps:
