Hi, I'm Zoho One user, looking for a better solution how to create Auto-reply messenger bot, when customer send us a private message, example "pm" or "I'm interested in your product", during the Facebook Campaign. 
I want the bot be able to filter the message and auto create lead as a contact into Zoho CRM. 

I'm looking any possibility to perform this within Zoho Social and Zoho SalesIQ which integrated with Zoho CRM
