| Field        | Type     | Required | Default | Description                                                                                                                                                                                                                        |
| ------------ | -------- | -------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `customerId` | `string` | Yes      | —       | The ID of the target customer profile.                                                                                                                                                                                             |
| `key`        | `string` | Yes      | —       | The key of the custom attribute to delete. This key must match the `key` of a custom attribute definition in the Square seller account. If the requesting application is not the definition owner, you must use the qualified key. |
