WhatsApp Business API in Kolkata
The WhatsApp Business API is Meta's programmable interface that lets a business send and receive WhatsApp messages at scale, with automation, chatbots and CRM integration. In Kolkata it helps retailers, clinics, schools and service businesses message customers in Bengali, Hindi or English without managing chats by hand.
Run WhatsApp notifications, campaigns and support for your Kolkata business with approved templates, a shared team inbox and chatbot automation. ConnexBetter onboards and supports Kolkata teams remotely, with demos over video call.
Why Kolkata businesses use the WhatsApp Business API
Kolkata has a large base of retail, healthcare, education and financial-services businesses, and many customers prefer to be addressed in Bengali. The API supports templates in Bengali, so a business can send appointment reminders, payment nudges and festive offers in the language customers actually read.
Languages you can send in: Bengali, Hindi, English.
