You will want to get the Hosted Checkout username and password for the Merchant account before you get started with your ECOM site.
In limited cases we can deploy the software using only our developer credentials for testing before the Merchant account is ready for transactions.
If you are unsure how to get the credentials, an employee can contact Vantiv customer support and they will walk that person through the process. Vantiv will require the account owner (or an employee user granted sufficiently high credentials) to issue this themselves, their support team cannot issue the credentials on behalf of the Merchant.
In most cases we have access to the portal and can issue these credentials for you as well. When we do the installation ourselves we handle this process in house except in rare cases.
The website where these values are accessible is https://portal.mercurypay.com

Paste in your username and password into that window and we'll update your API key credentials, typically within 24 hours.
If you are using an older version of the plugin, then follow these instructions instead. After you have your credentials, you'll want to paste both your Merchant ID and the generated password into your Live credentials field in the plugin:
Finally, when you are ready to go live, scroll up to "Test Mode" and change the plugin to run in Live Mode.
