# How to set up a 2dehands.be/2ememain channel

2dehands and 2ememain are Belgian online marketplaces for buying new and used items, services, and vehicles. 2dehands is the Belgian-Dutch version, while 2ememain is the Belgian-French version. 

In this article, you'll learn how to set up a 2dehands or 2ememain channel to create, update, and manage your 2dehands or 2ememain listings in Channable.

***

### Before you start

**You’ll need**

* An [**Admarkt** 2dehands seller account](https://www.2dehands.be/admarkt/) (pro account for 2dehands)

{% hint style="warning" %}
**Important:** A Pro (Admarkt) 2dehands seller account is required to set up a 2dehands channel. Currently, you can't set up a 2dehands channel with a regular seller account.
{% endhint %}

**Good to know**

* Log out of your 2dehands/2ememain account before starting to prevent issues during channel setup.
* Your 2dehands.be/2ememain connection may stop working after some time. If this happens, you'll see a 'failed API' error message which you can fix by [refreshing your connection](/get-started/getting-started/connections-in-channable/how-to-renew-a-connection.md).
* 2dehands.be/2ememain [supports the following HTML](http://ecg-icas.github.io/icas/doc/prod/feed-details.html#description): `<u>` `<em>` `<ul>` `<li>` `<p>` `<strong>` `<br>`.
