introduzione<\/h2>\n\n

In questo tutorial creeremo semplici esempi per inviare messaggi tramite l’API di WhatsApp utilizzando Java.<\/p>\n\n

Inizialmente, devi assicurarti che okhttp3 <\/a>la libreria \u00e8 pronta Perch\u00e9 useremo questa libreria In questo articolo per inviare messaggi a Ultramsg Gateway.<\/p>\n\n

Primo messaggio API WhatsApp utilizzando Java<\/h2>\n\n
