Chatbase API: Integration Guide for Developers
Chatbase ships two REST API versions. API v1 is the original integration path; API v2 is a modern redesign with structured error codes, cursor-based pagination, Server-Sent Events (SSE) streaming, and a cleaner response contract. This guide covers v2 exclusively — it is the forward path for all new integrations in 2026. By the end, you will know how to authenticate, send streaming chat messages, paginate through conversation history, handle rate limits, and feed fresh website content scraped with Apify into your Chatbase knowledge base.
Prerequisites: API v2 requires a Standard plan or above. Free and Hobby accounts cannot use the API. Check the pricing guide to evaluate upgrading.
