Please find here what are ChatPlus account, site, and agent.
Account is the ID issued when register to the free trial.
When you register to ChatPlus, there will be an agent who has an authority of super administrator. The super administrator is a person in charge who can manage agent's information and all the sites. This person can decide on contract plan and access to payment information.
Site is an unit of homepage on which ChatPlus is installed. ChatPlus can be managed to have a chat in multiple homepages with 1 ID for agents who are running multiple homepages alone.
If you have multiple sites, you can manage ChatPlus tracking code for each site. For example, when one agent received multiple chats from multiple sites, ChatPlus will let him know which customer came from which location, or distribute agents to each site, and operate to call for a specific agent according to homepages.
Agent is the ID that can access to ChatPlus. If you prepare multiple agents, they can login with different IDs and share chats to each agent.
ChatPlus enables to login from multiple devices by one agent. For example, prepare one common agent and login with multiple people, then it becomes possible to operate when a chat comes with one of the agents free to reply.
