# Add WhatsApp Cloud API Channel Connect NanoClaw to WhatsApp via the official Meta WhatsApp Business Cloud API. NanoClaw doesn't ship channels in trunk — this skill copies the WhatsApp Cloud adapter in from the `channels` branch. The mechanical steps under **Apply** carry `nc:` directive fences: an agent reads the prose and applies them, and a parser can apply them deterministically from the same document. Every directive is idempotent, so the whole skill is safe to re-run; anything a parser can't apply falls back to the prose beside it. ## Apply ### 1. Copy the adapter Fetch the `channels` branch and copy the WhatsApp Cloud adapter into `src/channels/` (overwrite — the branch is canonical): ```nc:copy from-branch:channels src/channels/whatsapp-cloud.ts src/channels/whatsapp-cloud-registration.test.ts ``` ### 2. Register the adapter Append the self-registration import to the channel barrel (skipped if the line is already present). This one line is the skill's only reach-in into core: ```nc:append to:src/channels/index.ts import './whatsapp-cloud.js'; ``` ### 3. Install the adapter package Pinned to an exact version — the supply-chain policy rejects ranges and `latest`: ```nc:dep @chat-adapter/whatsapp@4.29.0 ``` ### 4. Build and validate Build guards the typed `createChatSdkBridge(...)` core call and proves the dependency is installed — the import throws at evaluation if `@chat-adapter/whatsapp` is missing or the barrel drifts: ```nc:run effect:build pnpm run ...
