Overview

This article provides a step-by-step guide on how to integrate the Nuvei payment gateway with your online store. Nuvei is a secure and reliable payment processing solution that allows you to accept payments from customers. By following these instructions, you can seamlessly add Nuvei as a payment gateway for processing transactions on your website(s).

Integration Process

Follow these steps to integrate the Nuvei payment gateway with your online store:

1. Sign Up for a Nuvei Account: Go to Settings > Payments > Gateways and click "Sign Up" to register through your online store dashboard. You will need to wait on the approval process through Nuvei to proceed. They should reach out to you via email for further details on your business. Once approved, return to the sign up page, but select "Existing Nuvei Account Enrolled with Cart.com" instead.
2. Access Merchant Portal: Log in to your Nuvei merchant portal. This is where you'll configure your payment settings and gather the API credentials.
3. Generate API Credentials: In the merchant portal, navigate to Settings > Integration Settings to locate your Merchant ID, Secret Key, and Site ID.
   
   
4. Connect your Online Store: Within your online store dashboard, access the payment gateway settings via Settings > Payments > Gateways > New > Sign Up. If your Nuvei account is already set up, select Existing Account and enter the Merchant ID, Secret Key, and Site ID from the previous step. If you do not have an account yet, you can optionally register at this point. 
5. Enable Nuvei: To activate the gateway, you can apply the gateway to "All" stores, or a specific store.

Account Approval

When you first register for an account with Nuvei, you will be subject to their approval process. You should receive an email shortly after signing up to initiate the approval process.
