Linq

Linq é uma plataforma de mensagens API-first que permite alcançar pessoas no iMessage, SMS e RCS por meio de conversas reais. O Linq cuida da infraestrutura de mensagens — entrega Apple e de operadoras, group chats, read receipts, indicadores de digitação, reações e anexos — por trás de uma única REST API projetada para acesso programático.

Por que Linq?

• iMessage, SMS e RCS em uma API: Enviar e receber nos três canais a partir dos mesmos chats e números de telefone, com entrega automática pelo melhor serviço disponível.
• Conversas ricas: Mídia, previews de links, efeitos de tela e bolha, reações tapback, respostas inline, memos de voz e mensagens editáveis — não apenas texto simples.
• Gestão de group chats: Criar grupos, adicionar e remover participantes, renomear chats, atualizar ícones e sair de conversas.
• Verificações de capability: Verificar se um endereço suporta iMessage ou RCS antes de enviar, para escolher o canal certo sempre.
• Webhooks em tempo real: Inscrever-se em eventos de mensagem, reação, participante e chamada com verificação de assinatura HMAC-SHA256.

Usando o Linq no Zoen

A integração Linq do Zoen conecta seus fluxos agentic diretamente ao Linq usando uma API key. Com 34 operações abrangendo chats, mensagens, anexos, números de telefone, verificações de capability, contact cards e assinaturas de webhook, você pode construir automações de mensagens conversacionais sem escrever código de backend.

Principais benefícios de usar o Linq no Zoen:

• Agentes conversacionais: Enviar e ler mensagens em chats iMessage, SMS ou RCS, reagir com tapbacks e responder inline para construir conversas naturais de duas vias.
• Entrega confiável: Verificar capability de iMessage/RCS e definir um serviço preferido para que cada mensagem saia pelo canal certo.
• Arquivos e voz: Fazer upload de anexos de até 100MB e enviar mídia ou memos de voz direto do seu fluxo de trabalho.
• Fluxos orientados a eventos: Gerenciar assinaturas de webhook para que os fluxos reajam a mensagens de entrada, reações e mudanças de participantes.
