Feishu Integration Developer

If your team or your China-based partners run their workflow inside Feishu (Lark), the tools you build need to live there too (as bots, custom apps, and workflow automations on the Feishu Open Platform) rather than as a separate app people have to remember to check. We build these integrations directly against Feishu's API, handling authentication, event subscriptions, and the platform's specific approval process. This is the right service when you need approvals, notifications, or data sync to happen inside the chat and workflow tool your team already lives in, instead of adding one more disconnected system. You get a bot or workflow that behaves like a native part of Feishu, not a bolted-on widget.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Map the workflow you want inside Feishu (approvals, notifications, data sync) and the events that should trigger it.
2
Build a working bot or app against one real workflow, testing Feishu's auth and event model directly.
3
Review the bot's behavior with actual users in your Feishu workspace before expanding scope.
4
Complete the integration and submit it through Feishu's app approval process for organization-wide rollout.
