Example coordination patterns: - **Researcher → WhatsApp** — the Researcher (GPT-5.5) pulls context from WhatsApp (records, threads, documents), synthesises findings, and briefs the rest of the team. - **Writer → Distributor → WhatsApp** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into WhatsApp (create record, post message, draft email). - **Designer / Engineer → Distributor → WhatsApp** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via WhatsApp (attach file, open PR comment, post status). The Verifier checks every WhatsApp call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention. ## Categories - phone & sms — https://definable.ai/apps/category/phone-&-sms/ - communication — https://definable.ai/apps/category/communication/ ## Related - HTML page: https://definable.ai/apps/whatsapp/ - Same category (phone & sms): https://definable.ai/apps/category/phone-&-sms/ - All integrations: https://definable.ai/apps/ - Workflow (multi-agent loop): https://definable.ai/workflow/ - Apps llms.txt index: https://definable.ai/llms-apps.txt
