If you are currently using a classic library, you need to migrate to [Terminal API](/point-of-sale/design-your-integration/terminal-api).\ Do not build a new integration with a classic library. Partial authorization allows the shopper to pay for their goods with another card, if the balance of their primary card is less than the value of the goods. The tender option  `AllowPartialAuthorisation` is used to enable partial authorizations on a tender. 1. Initiate a transaction with `CreateTender` including `AllowPartialAuthorisation` as a tender option. 2. A request for payment is returned from the Adyen payments platform which includes the `allowPartialAuthorisation` parameter as part of the `AdditionalData` object. 3. Confirm the authorization with the `ConfirmAdditionalData` response, including the following parameters: | Element | Details | | -------------------------- | ----------------------------------------------------------- | | `authorisedAmountValue` | The value available to partially authorize from the card. | | `authorisedAmountCurrency` | The currency of the balance being authorized from the card. | | `requestedAmount` | The total value of the tendered goods. |
