For Helcim merchants using the legacy Helcim Gateway, you can find instructions at the link below (we strongly recommend you migrate to Helcim Commerce):

Helcim.js vs. Direct API Integration

Our WooCommerce plugin offers two integration modes:

Helcim.js Helcim.js is recommended as it greatly reduces your security and PCI compliance scope. The credit card tokenization takes place between your client's web browser and Helcim's servers, removing your server from having to touch full credit card information. However, Helcim.js does not work with some older browsers and can conflict with other plugins installed on your WordPress website.

Direct Integration The direct integration providers a more straight-forward payment integration, but brings your server into the full scope of PCI compliance. Merchants should choose their integration mode based on their security practices.

Web-Server Requirements and Testing

Both integration methods require your server to be able to perform CURL requests. Transactions are sent to using port 443. Helcim Commerce uses TLS1.2 and only strong TLS cypers, you can view a list here.

You may need to work with your hosting provider to make sure that your firewall rules allow outbound access to the URL and port listed avove. When installing the plugin to your WordPress and WooCommerce installation, we recommend performing transactions in test mode first before switching to production (live). You can find test credit card numbers here.
