The correct answer is Under the API Reference within the Developer Portal. Klaviyo does not apply a single, blanket rate limit to all of its APIs. Instead, limits are assigned on a per-endpoint basis to account for the different computational costs of various tasks (e.g., fetching a single profile vs. querying complex event data). How to Find the Limits. The Klaviyo Developer Portal is the source of truth for these specifications. When you view the documentation for a specific endpoint in the API Reference, you will find its assigned rate limit tier.
