Capture/Adjust

Overview

The capture command moves an authorized transaction into the current batch for settlement. It is possible to capture an amount other than the one originally authorized, however, you must follow the guidelines established by the merchant service bank. Capturing a higher or lower dollar amount could result in additional penalties and fees.

Most banks typically allow no more than 10 days to pass between the authorization/capture and settlement of a transaction.

If you do not wish to capture a previously authorized transaction, you may void the original authorization rather than capturing a 0 dollar amount, or simply allow the captured transaction to time out.

The adjust command allows you to make changes to an existing (unsettled) sale. The authorization amount can be increased (incremental authorization) or decreased (partial reversal) or not changed. Additional data elements such as tax amount and po number can be added. The tolerances for the settle amount vary depending on the type of Merchant Account and the merchant service provider. The adjust and capture commands function identically except that the adjust command does not place the transaction in the batch.

The API endpoint is as follows:

POST /api/v2/transactions

Capture Error

Captures a transaction. If the authorization has expired, the command will throw an error.

curl -X POST https://sandbox.newtekgateway.com/api/v2/transactions
  -H "Content-Type: application/json"
  -H "Authorization: Basic X1Y4N1F0YjUxM0NkM3ZhYk03UkMwVGJ0SldlU284cDc6czIvYWJjZGVmZ2hpamtsbW5vcC9iNzRjMmZhOTFmYjBhMDk3NTVlMzc3ZWU4ZTIwYWE4NmQyYjkyYzNkMmYyNzcyODBkYjU5NWY2MzZiYjE5MGU2"

Capture Reauth

Developers can capture transactions using the cc:capture:reauth command. If the authorization has not expired, it will place the transaction in the batch for settlement. If the authorization has expired, it will attempt to reauthorize the same card. The developer does not need to know the state of the transaction ahead of time.

curl -X POST https://sandbox.newtekgateway.com/api/v2/transactions
    -H "Content-Type: application/json"
    -H "Authorization: Basic X1Y4N1F0YjUxM0NkM3ZhYk03UkMwVGJ0SldlU284cDc6czIvYWJjZGVmZ2hpamtsbW5vcC9iNzRjMmZhOTFmYjBhMDk3NTVlMzc3ZWU4ZTIwYWE4NmQyYjkyYzNkMmYyNzcyODBkYjU5NWY2MzZiYjE5MGU2"

   },
   "auth_amount": "100.00"
}

This is the sample response object sent back from the server.

Capture Override

We do not allow setting the expiration time to longer that 30 days. We do however, have a “cc:capture:override” command that will force a capture, even if the authorization has exceeded the maximum 30 days. We would not recommend capturing transactions over 60 days due to the charge back risk.

curl -X POST https://sandbox.newtekgateway.com/api/v2/transactions
  -H "User-Agent: uelib v6.8"

   },
   "auth_amount": "3.00"
}

Refund Adjust

Interchangable with the command cc:refund:adjust. If the authorization has not settled yet, it will adjust the authorization amount down by the inputted amount (releasing funds back to the card holder in realtime). If the authorization has settled, a credit transaction will be submitted.

curl -X POST https://sandbox.newtekgateway.com/api/v2/transactions
  -H "Content-Type: application/json"
  -H "Authorization: Basic X1Y4N1F0YjUxM0NkM3ZhYk03UkMwVGJ0SldlU284cDc6czIvYWJjZGVmZ2hpamtsbW5vcC9iNzRjMmZhOTFmYjBhMDk3NTVlMzc3ZWU4ZTIwYWE4NmQyYjkyYzNkMmYyNzcyODBkYjU5NWY2MzZiYjE5MGU2"
