# PIX Keys

> Create or delete a PIX key for the authenticated account.

Manage PIX keys owned by the selected account.

### Endpoints

* Create PIX key — `POST /v3/pix_keys/create`
* Delete PIX key — `POST /v3/pix_keys/delete`

### Authentication and account targeting

All endpoints use signed POST requests. Send `X-Client-ID`, `X-Timestamp`, `X-Nonce`, and `X-Signature`. `X-Content-Hash` is optional for inbound API calls. If you use account-targeting headers, send `X-ISPB` and `X-Account-Number` together.

The credential must be allowed to access the selected account. Key ownership and key-type validation are enforced by the service.
