OpenClaw Integrations API

OpenClaw is a skill-based integration system that allows apps built on MakeX to discover and execute actions from third-party services (Gmail, Slack, GitHub, etc.) via Composio.

Authentication

All endpoints require the X-Org-Token header containing an organization service token. This token is validated against the organization database. User session cookies are not used — these endpoints are designed for server-to-server communication.

X-Org-Token: <org-service-token>

Don't have an org token?

1. Go to https://www.makex.app/ and sign up for an account.
2. Navigate to Settings in your dashboard.
3. Copy your API key from the settings page — this is your X-Org-Token.

Base URL

POST /api/openclaw/integrations/<endpoint>

All endpoints support CORS via a preflight OPTIONS handler.

Typical Workflow

1. Search actions to discover what's available for connected integrations.
2. Get connected account to retrieve the accountId for a specific integration.
3. Get action details to understand input/output parameters for a chosen action.
4. Run action to execute the action with the required arguments.
