I don't want my Support license taken up by a Chat user. How do I create a Chat-only agent when I have a Zendesk Support subscription as well?
Creating a Chat-only agent depends on what type of Chat version you use. To determine the Chat version you have, see the article: Determining your Zendesk Chat account version.
Create your Chat-only users from your Chat dashboard instead of creating the profile in Support. For detailed instructions, see this article: Creating agents and departments in Chat.
Chat agents will then be added to your Support account as users in the Contributor role. Contributors don't take a Support license. For more information about this role, see the article: Creating custom roles and assigning agents.
Create your Chat agent in your Support dashboard. Set the role for the user as Contributor in Admin Center. For more information on how to add agents, see the article: Adding agents and administrators.
Legacy Zendesk Chat + Support
Chat agents for legacy Chat accounts don't take a Support seat by default unless you add the user as an agent in your Support account. For more information, see the article: (Legacy Chat) Creating agents and departments
