Helcim.js transactions and the Payment API

The Helcim System has a number of backend payment systems that facilitate the processing and settlement of credit card transactions with their own unique id values. Completing subsequent actions through the Payment API expects a different transactionId value than the one returned by Helcim.js.

Retrieving the updated V2 API transactionId value would be required you want to Refund or Reverse Purchase transactions processed through Helcim.js, or Capture any Pre-Authorize Transactions through the Payment API.

To retrieve this value, we recommend calling the Collect Card Transaction endpoint with relevant query parameters to filter returned transactions down to the correct one. This could include a combination of values returned by Helcim.js, such as the date, cardHolderName, amount and cardToken for the transaction.

Based on this the Payment API will return a transaction object with a transactionId that can be used through all Payment API endpoints.
