If you want to use it, please contact your CSM. This operation enables transfer of balance from card A to card B. The balance is debited from the fromCard and credited to the toCard. The request will create two separate card level transactions, one debiting and one crediting that are visible in respective cards. The transactionType codes for the transactions are: •`C2CD` for the debiting transaction •`C2CC` for the crediting transaction The transactions are posted in a consecutive manner, first the debiting transaction followed by the crediting transaction. If either cardId is invalid, either card status prevents posting of transactions or if the available balance in the fromCard is not sufficient, the operation will fail. If the first debiting transaction fails, the process will be discontinued, and the crediting transaction will not be performed (`status`: `DEBIT_FAILED`). If the debiting transaction is successful but the crediting transaction fails, the debiting transaction will be automatically reversed (`status`: `FAILED_BUT_REVERSED`). ## OpenAPI ````yaml transfer post /v1/c2c openapi: 3.0.3 info: version: '1' title: Transfer API contact: name: Enfuce Financial Services url: https://enfuce.com email: info@enfuce.com x-logo: url: https://developer.enfuce.com/images/enfuce.svg altText: Enfuce logo servers: - url: >- https://integration-api-cat2.{{environment}}.ext.{{realm}}.cia.enfuce.com/transfer - url: https://integration-api-cat2.live.ext.prod.cia.enfuce.com/transfer description: Live environment security: [] tags: - name: Account to account batch transfer paths: /v1/c2c: post: tags: - Post card to card transfer summary: Transfer balance from card to card description: > Please note that this feature requires manual configuration.
