Clarification on API Call Limits and Daily Message Usage

Hello, In your documentation, you mention the following rate limit for API calls: "100 × number of users in the workspace messages per day." For example, if my workspace has 20 users, that would mean a limit of 2000 API calls per day. Could you clarify whether these API calls reduce the daily message limit for agent usage via your web interface, or are they counted separately? Thanks in advance for your clarification. Thank you !
