Hi @pavan ,
Will there be agents on their platform who will be responding on their behalf? In this case they can use our customer agent integration to raise a ticket and respond to users. Please reach out to Integration team for the same but there is no direct way for routing the messages to a third party platform and respond back to users in the same way.
We would suggest them to let their Agent Respond from our Agent Dashabord itself which has all the Agent actions and reporting available out of the box with NLP support for non operating hours where the Bot can take over.
