Lark Base: Comprehensive Agent-Usability Assessment

Docs-backed

Lark (Feishu internationally) is ByteDance's enterprise collaboration platform — a full suite covering messaging, docs, sheets, meetings, and Base (spreadsheet/database). For agents integrating with Lark-centric organizations: the OpenAPI covers Lark Base tables (Airtable-like), docs, messages, and calendar. OAuth2 app-based auth adds setup complexity but is standard for Lark integrations. Strong in Asia-Pacific; growing globally. Confidence is docs-derived.

Lark Base: API Design & Integration Surface

Docs-backed

REST API at open.larksuite.com/open-apis/. Resources: bitable (Base tables), docs, messages, calendars. GET /bitable/v1/apps/{app_id}/tables lists Base tables. POST /bitable/v1/apps/{app_id}/tables/{table_id}/records creates records ({fields: {column_name: value}}). GET /bitable/v1/apps/{app_id}/tables/{table_id}/records/search searches records with filters. Response: JSON with data wrapper.

Lark Base: Auth & Access Control

Docs-backed

OAuth2: client_credentials or authorization code flow. App credentials from Lark Open Platform → Create App. Access tokens (app_access_token): POST /auth/v3/app_access_token/internal with app_id + app_secret. Tenant access token for user-scoped operations. HTTPS enforced. Token expiry: 2 hours; auto-refresh required. Chinese servers (feishu.cn) vs international (larksuite.com) — use correct domain per tenant.

Lark Base: Error Handling & Operational Reliability

Docs-backed

Token refresh is the primary operational concern — 2-hour expiry requires automated refresh. API rate limits per app (configurable via Lark Open Platform). Resource not found: 404 with error code and message. Lark platform uptime at status.larksuite.com.
