A chat server processes chat messages between the chat widget that is deployed on your webpages and your Pega Customer Service application. When you buy a license that includes the Pega Chat offering for Pega Customer Service 8.2 or later, a Pega Cloud Collaboration Services chat server account is provisioned for you. The authorized contact for your organization's Pega account receives an email that includes a private API key and the chat server hostname of your provisioned chat server account. The hostname of the Pega Cloud Collaboration Services chat server depends on the geographical region (for example, for the USA, it is https://us.chat.pega.com).
