Developer Documentation & Integration
Composio exposes a unified API that abstracts authentication and action execution across all supported integrations. Key developer-facing capabilities include:
- Managed OAuth & auth infrastructure — delegate the full OAuth lifecycle (authorization, token exchange, refresh) to Composio; no credential storage required in your application layer.
- SDKs — available for rapid onboarding; connect your agent framework and start executing actions against live apps with minimal boilerplate.
- MCP Gateway — route tool calls and agent actions through the Model Context Protocol gateway for standardized, framework-agnostic tool use.
- Context-efficient action selection — query Composio for only the actions relevant to a given task; avoids flooding the model context window with unused tool definitions.
- Isolated sandbox runtime — run multi-step agent workflows in an isolated execution environment to contain side effects.
- Framework integrations — native connectors for Vercel AI SDK and LangGraph are available among the 1,500+ integrations.
- Enterprise controls — SSO, governance policies, and audit logging are available on the Enterprise tier.
Supported integration categories include: productivity (Gmail, Slack, Notion, Google Workspace), DevOps (GitHub, Vercel, Sentry, Datadog, PagerDuty), CRM (HubSpot, Salesforce, Zendesk, Intercom), finance (Stripe, Xero, Brex, NetSuite), HR (BambooHR, Deel, Ashby, Lever), e-commerce (Shopify, Klaviyo, Gorgias), marketing (Google Ads, Meta Ads, Mailchimp), and more.
