A customer messages your store on WhatsApp. They ask about a product, check on their order, or want to know if something is in stock. That message opens what WhatsApp calls a conversation window.<\/p>\n\n\n\n
What most stores don’t realize is that window has a 24-hour limit. And once it closes, the rules of the game change entirely.<\/p>\n\n\n\n
The 24-hour rule is a WhatsApp Business API policy that defines when and how a business can send messages to its customers.<\/p>\n\n\n\n
The principle is straightforward: when a customer messages you, a 24-hour conversation window opens. During that period, you can reply freely, with no format restrictions and no additional cost per message. Text, images, documents, audio \u2014 whatever the context requires.<\/p>\n\n\n\n
When those 24 hours pass without activity from the customer, the window closes. To reach them again, you need to use a Meta-approved message template, which has a cost per send and must follow WhatsApp’s formatting guidelines.<\/p>\n\n\n\n
The goal of this policy is to protect users from unsolicited messages. For stores, it means understanding exactly when and how to communicate to avoid missing opportunities or incurring unnecessary costs.<\/p>\n\n\n\n
Shopify is the most widely used eCommerce platform globally. When integrated with WhatsApp Business API, the 24-hour rule directly impacts three critical moments in the sales process:<\/p>\n\n\n\n
Pre-purchase queries.<\/strong> A customer asks about size, color, or availability. If your team or AI responds within 24 hours, the conversation flows and the sale can close. If there’s no response in that window, the customer is no longer reachable on the free channel \u2014 you’ll need a template to re-engage.<\/p>\n\n\n\n Cart abandonment.<\/strong> This is the most sensitive case. If the customer initiated a conversation with you before abandoning, you have 24 hours to send a reminder within the open window at no extra cost. After that, follow-up requires an approved template.<\/p>\n\n\n\n Post-sale communication.<\/strong> Order confirmations, shipping updates, review requests. Everything you want to communicate after purchase must arrive within the active window or through templates. Planning those messages in advance is the difference between efficient and expensive communication.<\/p>\n\n\n\n Understanding the exact limits prevents operational errors and unexpected costs.<\/p>\n\n\n\n Within the open window you can:<\/strong><\/p>\n\n\n\n Outside the window you must:<\/strong><\/p>\n\n\n\n The key operational move for Shopify stores is configuring automated flows that act within the window. When a customer messages and doesn’t get a response for hours, the window stays open but the opportunity goes cold.<\/p>\n\n\n\n The 24-hour window isn’t a restriction. It’s an opportunity with an expiration date.<\/p>\n\n\n\n Shopify stores that get the most out of this rule do three things:<\/p>\n\n\n\n They respond fast and automatically.<\/strong> With conversational AI, every incoming message gets a response in seconds, regardless of the hour. That activates the window and starts the sales flow from the first message.<\/p>\n\n\n\n They execute follow-up within the window.<\/strong> If a customer asked about a product but didn’t buy, the reminder goes out within the first few hours \u2014 not the next day. Every hour that passes reduces the probability of conversion.<\/p>\n\n\n\n They have templates ready for when the window closes.<\/strong> Not everything can be resolved within 24 hours. Stores with well-configured templates for cart recovery, order confirmation, and inactive customer reactivation minimize cost and maximize reach.<\/p>\n\n\n\n ChateCommerce automates that entire flow for Shopify stores: immediate response within the window, smart follow-up before it closes, and optimized templates for when time runs out.<\/p>\n\n\n\n ChateCommerce is fully in English \u2014 setup, dashboard, and support. <\/p>\n\n\n\n Create your account and start making the most of every conversation window today.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" A customer messages your store on WhatsApp. They ask about a product, check on their order, or want to know if something is in stock.
