10/13/2025, 8:00 AMThanks for your question!
Based on the documentation, Vapi enforces concurrency limits at the organization level (e.g., 10 concurrent lines per org by default), but it does not specify if rate limiting is based on IP address or API key.
To help clarify your use case:
Are you asking about rate limiting for API requests, call concurrency, or something else (like webhook events)?
This will help me provide the most accurate answer for your scenario.
