API Identifier
This is a random string of numbers and characters that is given to you by an OpenGateway Service Provider. For security reasons, it should be kept secret. If you suspect it is no longer secret, contact your Service Provider.

API Secret Key
This is a random string of numbers and characters that is given to you by an OpenGateway Service Provider. It should be kept absolutely secret as it essentially acts as your password when communicating with the OpenGateway platform. If you suspect it is no longer secret, contact your Service Provider.

Recurring Plans
A recurring plan is a set of data including charge amount, interval, and notification_url grouped under a "Plan Name". Plans are useful when you want to group like recurring charges. For example, if you offer a service for $5 per month, you can create a plan that charges $5 every 30 days. Then, when you want to create a recurring charge for that plan, you will simply pass the plan_id in the recur node during a Recur charge. The customer will then be charged $5 every 30 days and their account will be linked to this plan.

Root installation folder
This is the folder/subdomain on your website where you installed the OpenGateway server. So, if you uploaded your files to /var/www/vhosts/yourdomain.com/httpdocs/opengateway/, your root installation folder is likely accessible via the web at http://www.yourdomain.com/opengateway.
