API Overview

2 minutes to read

The Caspio REST API lets you extend your Caspio applications, automate workflows, and integrate with external systems. Built on industry-standard REST and designed for AI agents and MCP integrations.

API Versions

Caspio supports two active versions of the REST API:

v4 — The latest version, optimized for high-volume workloads, advanced querying, and AI-driven integrations. Covers all v3 operations and extends them with bulk operations, direct record access by ID, T-SQL queries, schema discovery, and an AI manifest endpoint for AI agents and MCP integrations.
v3 — The previous version, fully supported for existing integrations. Provides record and design operations for tables and views, plus access to files, directories, tasks, outgoing webhooks, and Bridge applications.

Use v4 for all new integrations. Existing v3 integrations continue to work without changes, so you can migrate to v4 at your own pace when you need its additional capabilities.

REST API v1 and v2 are deprecated and no longer supported.
