API extension is how a Lark robot becomes connected to real systems: tickets, dashboards, approvals, and internal tools. The key is to extend safely: strict allowlists, permission checks, and structured outputs.
OpenClaw is designed for this style of tool calling. Deploying on Tencent Cloud Lighthouse gives you a stable 24/7 runtime that’s simple, high performance, and cost-effective.
# lark-api-tools.yaml
tools:
get_incident:
method: GET
path: /incidents/{id}
allow_roles: ["oncall", "admin"]
Once one extension is safe, adding more becomes routine.
