Request Requirements

In order to process a Refund Transaction, the original transaction must be in a closed credit card batch. If the credit card batch of the transaction remains open, you should use the Process Reverse Transaction endpoint.

// Example Refund request
const options = {
  method: 'POST',
  headers: {
    accept: 'application/json',
    'idempotency-key': 'Idempotency20240514test14',
    'content-type': 'application/json',
    'api-token': 'YOUR_API_TOKEN'
  },
  body: JSON.stringify({
    originalTransactionId: 25509391, 
    amount: 11, 
    ipAddress: '192.168.1.1'
  })
};

fetch('https://api.helcim.com/v2/payment/refund', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

Potential Payment Responses

The Process Refund Transaction endpoint will respond to all requests with either:

• A transaction object with a type of 'refund', indicating the outcome of the payment.
• An error response indicating the reason for the error.
