WhatsApp in Kolkata: questions, answered.

Clear answers to the questions we hear most. If yours is not here, ask us directly.

Is the WhatsApp Business API different from the WhatsApp Business app?

Yes. The app is meant for small businesses using one phone. The API connects a verified business number to your systems and supports multiple agents, automation and higher volumes.

Do I need approved templates to message customers in Kolkata?

Yes. Business-initiated messages use templates approved by WhatsApp, and customers must have opted in. We help you prepare and submit templates.

Can customers in Kolkata reply to my messages?

Yes. Conversations are two-way, and replies land in a shared inbox for your team or can be handled by a chatbot.

How long does it take to get started?

Timelines depend on business verification and template approval. We guide you through the setup and share the steps during onboarding.

How much does the WhatsApp Business API cost in Kolkata?

Pricing depends on the conversation category and your monthly volume. Share your use case and expected volume and our team will send a quote.
