Enabling WhatsApp in a chatbot application
BMC Helix Innovation Suite provides a WhatsApp conversation capability for chatbot applications so that the application users can interact with a chatbot through WhatsApp messages by using their mobile devices.
As an administrator, to utilize this capability, you must use the service provided by Twilio. The configuration for BMC Helix Virtual Agent to work with Twilio is a tenant-level configuration.
- If you use Twilio to configure BMC Helix Chatbot for SMS conversation, you require two different services of Twilio. You cannot use a single Twilio service for SMS and WhatsApp configuration.
- End users can use the same number for WhatsApp and SMS conversations.
