asanaAsana API integration with managed OAuth. Access tasks, projects, workspaces, users, and manage webhooks. Use this skill when users want to manage work items, track projects, or integrate with Asana workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

https://gateway.maton.ai/asana/{native-api-path}
Replace {native-api-path} with the actual Asana API endpoint path. The gateway proxies requests to app.asana.com and automatically injects your OAuth token.
All requests require the Maton API key in the Authorization header:
Authorization: Bearer $MATON_API_KEY
Environment Variable: Set your API key as MATON_API_KEY:
export MATON_API_KEY="YOUR_API_KEY"
Manage your Asana OAuth connections at https://ctrl.maton.ai.
