# Delete Custom Field

> Delete a custom field from a business.

```
delete_custom_field
```

## Description

Deletes a custom field from a business. Use it to remove a field that is no longer used or one created by mistake.

<Warning>
  This action **cannot be undone** — the custom field definition (and any values stored under it) is permanently removed. State exactly which field will be deleted and confirm with the user before proceeding.
</Warning>

## Parameters

| Parameter        | Type    | Required | Default | Description                                                                                                               |
| ---------------- | ------- | -------- | ------- | ------------------------------------------------------------------------------------------------------------------------- |
| `fieldId`        | integer | Yes      | —       | ID of the custom field to delete. Resolve via [`get_custom_fields_list`](/mcp/tools/custom-fields/get-custom-fields-list) |
| `businessNumber` | string  | Yes      | —       | Business number that owns the field                                                                                       |

## Example Usage

```
Delete custom field 376.
```

```
Remove the "Legacy ID" custom field.
```

## Notes

* Returns a success response when the field is deleted.
* Resolve `fieldId` via [`get_custom_fields_list`](/mcp/tools/custom-fields/get-custom-fields-list) (match the field by name) if the user refers to the field by name rather than ID.
