Exotel is a voice communication platform that facilitates making automated calls for businesses and marketing to engage customers.
You can use Exotel's API to pass lead information from Lemnisk CDP to the Exotel call database. This use case demonstrates the configuration of Exotel's voice call API and feeds data from Lemnisk for businesses to engage customers through voice calls.
In the following use case, we will configure Exotel's API at the global level, as the payload value will remain the same for all engagements.
