WhatsApp Business API

DecisionTelecom WhatsApp API позволяет отправлять и получать деловые сообщения WhatsApp в любую страну мира и из нее через API. Каждое сообщение идентифицируется уникальным случайным идентификатором, поэтому пользователи всегда могут проверить статус сообщения, используя заданную конечную точку.

WhatsApp API использует HTTPS с ключом доступа, который используется в качестве авторизации API. Полезные данные запросов и ответов форматируются как JSON с использованием кодировки UTF-8.

API Авторизация - Базовый ключ доступа Base64.

Чтобы получить ключ API, пожалуйста, свяжитесь с вашим менеджером по работе с клиентами.
