# Submerchant Update
This service allows you to update submerchant accounts by providing their necessary details.
{% hint style="info" %}
In the process of updating submerchants, it's important to note that you **cannot** change the submerchant type. Once a submerchant is created with a specific type, it cannot be modified to a different type. Therefore, it's crucial to ensure that the correct submerchant type is selected during the initial setup.
{% endhint %}
All of the submerchant types are capable of update operations;
* **PERSONAL**
* **PRIVATE COMPANY**
* **LIMITED OR JOINT STOCK COMPANY**
