Definition
A WhatsApp chatbot is software that conducts conversations with customers on a business's WhatsApp number automatically, via the Business API. Implementations range from rule-based flows (keyword triggers, button menus, decision trees) to AI assistants powered by large language models with retrieval over the business's own catalog and policies. Typical jobs: instant FAQ answers, catalog browsing and order capture, lead qualification from click-to-WhatsApp ads, appointment booking via Flows, order-status lookups, and after-hours coverage with human handoff rules. Bot replies inside the 24-hour service window are free, which makes automation the economic core of inbound WhatsApp commerce: the bot absorbs volume at zero marginal message cost and escalates the conversations that need a person.
How it applies in India
Indian deployments lean on chatbots for scale and language: a bot that answers in Hindi or Hinglish at 11 p.m., quotes a price from the catalog, and collects a UPI payment replaces work an SMB owner was doing from a personal phone. Common India patterns include COD-confirmation bots (cutting return-to-origin losses), CTWA lead-qualification bots that tag the source ad, and order-status bots fed from the merchant's logistics or OMS stack. WatEase ships a no-code flow builder plus an AI assistant grounded on the merchant's catalog and FAQs, with human takeover in the shared inbox.
Frequently asked questions
Do chatbot messages cost money?
Replies the bot sends inside the customer's 24-hour service window are free — no template or per-message charge. Costs only arise when the bot (or business) initiates contact outside an open window, which requires a paid template in the Marketing, Utility, or Authentication category.
Does Meta need to approve my chatbot?
No separate bot approval exists. The bot operates under your normal API account: templates it sends still need approval, commerce-policy rules still apply, and Meta requires an escalation path to a human for customer support. Quality rating applies to bot traffic the same as human traffic.
Rule-based flow or AI chatbot — which should I use?
Use rule-based flows for structured tasks with finite paths (order status, booking, COD confirmation) — they are predictable and cheap. Add an AI layer for open-ended questions where intent varies (product advice, support triage), grounded on your catalog and policies with a human-handoff threshold. Most production setups combine both.
