{% hint style="info" %}
**Customer Groups** must be created first in the **SenderWiz Admin Panel**. Each group controls what a customer can or cannot do — such as whether they can create/upload lists, how many contacts they can manage, or how many emails they’re allowed to send, and many other settings.

\
👉 Use the **Group Name** (e.g., `"Pro-Group"`) in the `group` parameter when updating the customer.

🧩 To make a customer a **child account**, provide the `parent_uid` of an existing (non-child) customer account. 🚫 A customer that is already assigned as a child **cannot be set as a parent**.
{% endhint %}

{% hint style="info" %}
You can also update the `status` of a customer:

* **Active** – For active customers.
* **Inactive** – Customer data remains, but login and any activity including sending are disabled.
  {% endhint %}

Use this block to update any company-related information associated with the customer.

| Field       | Type   | Required | Description            |
| ----------- | ------ | -------- | ---------------------- |
