Add WhatsApp Cloud Channel

Wires the official Meta WhatsApp Business Cloud API into NanoClaw — adapter copy, registration, pinned dependency, credentials and webhook setup.

Web & APIIntermediate★ 30,471⑂ 12,865AI score 7/10Last updated: Aug 9, 2026

What it does

  • Pulls the WhatsApp Cloud adapter from the channels branch into src/channels/.
  • Appends the self-registration import to src/channels/index.ts and installs @chat-adapter/whatsapp at an exact pinned version.
  • Runs pnpm run build plus a vitest registration test that fails if the barrel import or dependency drifts.
  • Prompts for the four Meta values (access token, Phone Number ID, app secret, verify token) and writes them to .env without overwriting existing values.
  • Explains the shared webhook server (/webhook/whatsapp-cloud, port 3000), tunnel options, and an upgrade path for older whatsapp-keyed installs.

Who it's for

  • NanoClaw operators who want 1:1 WhatsApp conversations with their agent.
  • Teams that need Meta's official Cloud API rather than an unofficial bridge.
  • Anyone who keeps getting stuck on webhook verification or expiring tokens.

Examples

  • "Add the WhatsApp Cloud channel" → copy, register, install, build and test in order.
  • Migrating an older install → move the callback URL to /webhook/whatsapp-cloud and re-engage subscribed threads.
  • Calls start returning 401 after a day → swap the temporary token for a permanent System User token in WHATSAPP_ACCESS_TOKEN.

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the .claude/skills/add-whatsapp-cloud folder from the GitHub repo nanocoai/nanoclaw into my ~/.claude/skills/add-whatsapp-cloud/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/nanocoai/nanoclaw.git /tmp/nanoclaw && mkdir -p ~/.claude/skills && cp -r /tmp/nanoclaw/.claude/skills/add-whatsapp-cloud ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal in your working directory.
  2. Clone the repo: git clone https://github.com/nanocoai/nanoclaw.git
  3. Copy the skill: mkdir -p ~/.claude/skills && cp -r nanoclaw/.claude/skills/add-whatsapp-cloud ~/.claude/skills/
  4. Start Claude Code from the root of your NanoClaw project (the skill assumes that repo layout and pnpm).
  5. Ask: "Add the WhatsApp Cloud channel" so the Apply steps run.
  6. In Meta for Developers create a Business app, add the WhatsApp product, and collect the Phone Number ID, a permanent System User token with whatsapp_business_messaging, the App Secret and your Verify Token.
  7. Expose port 3000 publicly (e.g. ngrok http 3000), set the webhook to https://your-domain/webhook/whatsapp-cloud in the Meta dashboard, then restart the service and click Verify and save.
