A WhatsApp Business API gateway on the official Meta Cloud API. Inbound messages arrive at your webhook, outbound messages go through a REST API, and the number keeps working in the WhatsApp app on the phone at the same time, through Meta's Coexistence.
Built for developers, makers and agencies in Brazil who already have a bot, an automation or an AI agent on WhatsApp and need the number not to be blocked by using an unofficial reverse-engineered client.
curl -X POST https://api.zapclaw.app/api/v1/send/text \
-H "X-API-Key: zc_live_..." \
-d '{ "from": "5511...", "to": "5511...", "text": "Order #1234 is confirmed" }'- chatwoot-zapclaw, connect Chatwoot self-hosted to the official WhatsApp Cloud API without going through Meta App Review yourself. Two environment variables and a restart.
Honest limits, because finding them out an hour in is worse than reading them now. These come from Meta's Coexistence mode and no provider can lift them: throughput is fixed at 20 messages per second, there is no support for groups, voice or video calls, ephemeral messages or the Official Business Account green badge, and messages the business sends from WhatsApp for Windows or WearOS do not generate webhooks. It is also not a tool for bulk broadcasting.
Running on the official API removes the ban risk that comes from reverse-engineered WhatsApp Web clients. It does not make an account unbannable: Meta can still restrict a WhatsApp Business Account for quality, policy or verification reasons.

O ZapClaw é um gateway de mensagens do WhatsApp na API oficial da Meta Cloud, com Coexistência: as mensagens recebidas chegam no seu webhook, o envio é feito por uma API REST, e o número continua funcionando no aplicativo do celular ao mesmo tempo.
Serve para quem já construiu uma automação, um chatbot ou um agente de IA no WhatsApp e precisa que o número não seja bloqueado. Sem CNPJ para conectar, e números ilimitados nos planos pagos.
WhatsApp é marca registrada da Meta Platforms, Inc. O ZapClaw não tem vínculo com a Meta nem é endossado por ela.
