When integrating payment processing, we recommend that you make API calls in
test mode to avoid the live authorization of transactions until your project is ready for production. You can learn more about this here.
You can also set your Helcim.js configuration to be in test mode.
If your project calls for a developer sandbox outside of the live Helcim account, simply contact our team and they will create a developer account for you.
