Payment providers and partners must use this token to report the status of asynchronous payment transactions via a [callback URL](/en/docs/tutorials/payment-provider-protocol#callback-url).  \n\nAs of May 27, 2024,  the VTEX gateway will automatically include the callback URL information and the respective authentication token with each payment transaction.\n\nExample of a callback URL containing the authentication token:\n\n`https://gatewayqa.vtexpayments.com.br/api/pvt/payment-provider/transactions/8FB0F111111122222333344449984ACB/payments/A2A9A25B11111111222222333327883C/callback?accountName=teampaymentsintegrations&X-VTEX-signature=R123456789aBcDeFGHij1234567890tk`\n\n## What needs to be done?\n\nStarting June 26, 2024, all payment providers and partners must report the status of asynchronous payment transactions exclusively via the callback URL and authentication token.\n\nAfter this date, any transaction status updates sent only via callback URL (without the authentication token) will be blocked, and the respective payment transactions will be canceled.\n\nFor more information about the callback URL, see [Payment Provider Protocol](/en/docs/tutorials/payment-provider-protocol#callback-url) and [Create Payment endpoint](https://developers.vtex.com/docs/api-reference/payment-provider-protocol#post-/payments)."}
