Possiamo inviare immagini, documenti e media convertendo i file in base64.
converti File in Base64 usando l’interfaccia utente di ultramsg
puoi convertire qualsiasi file usando File in Strumenti Base64 dal menu Ultramsg dopo aver effettuato l’accesso al tuo account in Ultramsg.
passo 1: converti l’immagine in Base64:
passaggio 2: Invia immagini WhatsApp come Base64:
Possiamo semplicemente mettere Base64 invece del collegamento HTTP come mostrato nell’immagine seguente:
