Authorizations place a hold on the cardholder open-to-buy or available credit amount. This amount is subtracted from the cardholder's available credit and held to insure a future purchase. The response is logged in the transaction log, and if approved by the issuer, stored in the active database or it may be added to an existing authorization with the same reference number and cardholder account number.

- Authorization is the beginning of an electronic payment transaction. Tracking data is received from the transaction processor and card-issuing bank and automatically stored and sent during settlement.
- The token or Unique ID in the POS application (not required to retain customer account number) from the original authorization is used in the settlement process, if a subsequent sale transaction is processed.

:::notice{important}
To ensure Return (09) transactions are processed correctly, merchants must retain the PS2000 data returned in API field 0740 (Return compliance data) for Auth and Sale transactions. Field 0740 values must be sent unaltered with Return transactions. **Data in 0740 may vary in format depending on card brand and transaction type.**
:::

## Account verification
A $0.00 authorization transaction can be used for account verification and to confirm AVS, CVV2, CVC2 or CID values. Zero-dollar authorizations must be settled in the defined time frame to avoid misuse fees.

- Transaction is stored in Fusebox, but is not a financial transaction that can be used later for settlement or incremental authorization.
- Does not place a hold on a customer's open-to-buy.
- Transaction can be added to an existing authorization for the same transaction.
- AVS (Billing ZIP Code and Billing Street Address) and CVV2, CVC2, or CID required.
- Does not require full authorization reversal.


## Voice Authorization			
If an Authorization Only (01) is initiated and the clerk receives a message to call for voice authorization, the transaction can be processed once the clerk calls in to obtain the approval code from the processor.				
				
To add the transaction to the database:
1. Submit Authorization Only transaction.				
2. Enter approval code received from the processor into Authorization Code (Field 0006).				
3. Set the Force Flag (Field 0012) value to 1.				
				
The transaction is recorded in the Elavon Gateway application database rather than submitted to the TPP for approval.				
				
The example below is a transaction with partial authorization acceptance approved original amount, and is for a manually entered authorization.				
				
:::notice{title="note"}				
The TPP interface you use determines the actual fields returned in the response. If the interface requires the data, it is returned in the format required by the processor.
