To set-up WhatsApp Marketing on Contlo, we make the use of GupShup- an partnership which allows in building conversational experiences. A similar process to that of setting up SMS with Contlo, the required credentials are providied by Gupshup, in an email thread.
These particular details are then fed into Contlo's platform and from here onwards, the WhatsApp integration and set-up is good to go. Automatically, the syncing will take place, of all your WhatsApp Subscribed Contacts and you go ahead and send campaigns.
