Configuring Insight to work with your Merchant Data Systems is extremely simple. Unlike other payment gateways, Merchant Data Systems’ gateway doesn’t use an API key, a signature, or any other special API credentials. Instead, you just use your Merchant Data Systems username and password.

If you are already receiving merchant services from Merchant Data Systems, you will likely have two accounts with them: one account for your merchant terminals and a second account for your payment gateway. You will need the username and password from your payment gateway account. Only enter your username and password if you are sure that it’s for your payment gateway account. If you do have multiple accounts with Merchant Data Systems and are unsure which is which, please contact them directly at 1 (800) 249-6377.

Click on the location button (house icon), then click settings. Once you're in the setting menu, click on the Gateway tab:
