Postman file

O Postman é uma ferramenta que tem como objetivo testar serviços RESTful (Web APIs) por meio do envio de requisições HTTP e da análise do seu retorno.

Sandbox API

Desenvolvimento
Você deverá utilizar a seguinte URL:
https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages
Crie sua conta na sandbox pelo link https://studio.posit.us/ e gere um token seguindo as instruções da tela. Navegue no menu “Webhook” e copie a URL POST (ela usa a “Chave”).No ambiente de desenvolvimento você não poderá enviar mensagens HSM, mas todos os demais recursos estão disponiveis para envio e recebimento.
