Hi,
Recently developed such requirement of Whatsapp Chatbot (Please see review). I can document full setup of whatsapp chatbot integrated with mail.
I have already developed many Whatsapp/SMS chatbots recently using Twilio, Azure bot service and AWS platform and working in production. I have vast knowledge on REST and SOAP services also. I also have knowledge on database and and recently created the bot for retail sector.
I can dedicatedly work on this requirement and give you delivery on time and can design as per your requirement.
I have integrated the bot with different channels like Whatsapp, Facebook, Twilio, slack, Microsoft office 365 Teams and many more channels.
Please message me so we can discuss more on
this.
