Podemos enviar imagens, documentos e mídia convertendo os arquivos para base64.
converter arquivo para Base64 usando a interface do usuário ultramsg
você pode converter qualquer arquivo usando as ferramentas File to Base64 no menu Ultramsg após fazer login na sua conta no Ultramsg.
passo 1: converter a imagem para Base64:
passo 2 : Envie imagens do WhatsApp como Base64 :
Podemos simplesmente colocar Base64 em vez do link HTTP Conforme mostrado na imagem a seguir:
