FAQ

Como enviar mensagens para vários números de telefone

Você precisa enviar várias solicitações de API, uma por número de telefone destino.

Por exemplo, para enviar uma mensagem para 10 números de telefone, você deve enviar 10 solicitações HTTPS independentes para a API.

Não existe opção para enviar múltiplas mensagens em uma única solicitação de API.

Como validar se um número de telefone pode receber mensagens do WhatsApp

Você pode validar se um determinado número de telefone está vinculado a uma conta do WhatsApp e pode receber mensagens.

A API fornece um endpoint para validar se um determinado número de telefone existe no WhatsApp.

O único requisito é ter pelo menos um número do WhatsApp conectado à plataforma na sua conta atual.

Para mais detalhes, consulte a documentação do endpoint da API aqui.

Antes de verificar se um número de telefone existe no WhatsApp, você também pode validar e normalizar o formato de uma lista de números de telefone usando o endpoint de validação de números. Esse endpoint apenas valida o formato correto E164 mas não verifica se o número está efetivamente no WhatsApp.

Observação: O número de validações de verificação do WhatsApp é limitado por mês com base no seu plano de assinatura. Por favor, verifique a tabela de preços para mais detalhes sobre os limites.
