Отправляйте изображения и документы WhatsApp, используя Base64

Мы можем отправлять изображения, документы и мультимедиа, конвертируя файлы в base64.

преобразовать файл в Base64 с помощью пользовательского интерфейса ultramsg

Вы можете преобразовать любой файл с помощью File to Base64 Tools из меню Ultramsg после входа в свою учетную запись в Ultramsg.

шаг 1: преобразовать изображение в Base64:

Шаг 2: Отправьте изображения WhatsApp в формате Base64:

Мы можем просто поставить Base64 вместо HTTP-ссылки, как показано на следующем рисунке:
