# Update category

> Update the data of an existing category.

You only need to send the fields you want to update.

<ParamField path="app_id" type="string" required>
  Your store ID in Jelou Shop.
</ParamField>

<ParamField path="category_id" type="integer" required>
  ID of the category to update.
</ParamField>

<ParamField body="name" type="string">
  Category name (max. 255 characters).
</ParamField>

<ParamField body="description" type="string">
  Category description (max. 255 characters).
</ParamField>

<ParamField body="order" type="integer">
  Sort position (min. 0, max. 999999). Must be unique within the same level (app + parent category + branch). The value `0` is treated as "unordered".
</ParamField>

<ParamField body="status" type="boolean">
  Category status (active/inactive).
</ParamField>

<ParamField body="parent_id" type="integer">
  Parent category ID (for hierarchy). Must exist in the same store. A category cannot be its own parent. Send `null` to make it a root category.
</ParamField>

<Note>
  The `name` must be unique within the same level (same store, parent category and branch). Duplicating it returns a `422` error.
</Note>
