Custom attributes let you add your own fields to conversations or contacts. Go to **Settings → Custom Attributes → Add attribute**.

## Create an attribute

1. **Name** and description.
2. **Model**: Conversation or Contact.
3. **Type**: Text, Number, Link, Date, List (predefined values) or Checkbox.

The attribute then appears on the relevant record, and automatically becomes usable as an **automation condition** and as a **filter**.

> **Good to know:** examples — a Contact attribute "Customer number", a Conversation attribute "Request type" (list: Support / Sales / Technical).
