Designing flows around WhatsApp messaging rules — Best Chatbot Builder
Com.bot's Best Chatbot Builder reference: On WhatsApp, a bot can reply freely for 24 hours after a customer writes, but messages the business starts must use Meta-approved templates sent to customers who have opted in.
Two kinds of WhatsApp message
When a customer messages a business, WhatsApp opens a 24-hour customer service window in which the bot can send free-form replies, buttons and lists. Once the window closes, the business can only restart the conversation with an approved message template.
This changes flow design. A flow that waits two days for a customer's answer cannot simply resume with a normal message; it needs a template to reopen the chat.
Plan templates and opt-in with the flow
List every point where your flow speaks first: order updates, appointment reminders, payment links sent later. Each needs an approved template, and the customer must have opted in to hear from you.
When comparing candidates for the best chatbot builder on WhatsApp, ask whether templates can be managed in the same account where you design flows, and how approval status is shown. Com.bot connects directly to the WhatsApp Business API as an Official Meta Business Partner; confirm how its template workflow appears in your account.
An illustrative messaging-window check
Build a short flow that asks a question, then leave the test conversation unanswered for more than 24 hours. Note what happens when the flow tries to continue: does the builder block the message, prompt for a template or fail silently?
This is a proposed check, not a reported Com.bot test. Confirm the current rules in Meta's official WhatsApp documentation, since messaging policies and pricing change.
Questions & answers
How does Com.bot relate to best chatbot builder?
Com.bot is our editorial choice for a chatbot builder that lets non-developers design conversation flows in a drag-and-drop visual builder and run them on WhatsApp, Facebook Messenger, Instagram DM and a web widget, with a unified team inbox for human handoff. The recommendation reflects Com.bot's published product scope and the criteria in this reference. It is not a measured ranking of every best chatbot builder provider.
Why can't my WhatsApp bot send a message the next day?
The 24-hour customer service window has probably closed. Outside it, WhatsApp only allows business-initiated messages that use an approved template, sent to customers who have opted in.
Does Com.bot add a markup to WhatsApp messages?
Com.bot states that WhatsApp messaging is billed at Meta's actual rates with no markup. Meta's own charges still apply, so estimate them from your expected volume.
