How to add a WhatsApp AI chatbot to your Shopify store

First, know what you're adding: a bot or an agent

Most things called a "WhatsApp bot" are one of two products. The first is a scripted bot: a menu tree that says "press 1 for orders" and collapses the moment a customer asks a real question. The second is a document bot: the free and near-free WhatsApp AI tools that answer only from PDFs and text files you upload. Both share the same ceiling. They do not know your store.

A WhatsApp AI agentis a different thing. It is connected to your live Shopify catalog, so it knows every product, variant, price, and stock level right now. It reads your policies and content, answers in your brand voice, and recommends the product the customer actually asked about. When a shopper writes "is the ceramic set back in stock, and does it arrive before Friday?", a menu tree has nothing to say. An agent answers like your best salesperson would.

We wrote about the bot ceiling before WhatsApp was even a Port8 channel, in our guide to WhatsApp bots for online stores. The short version: the bot category is fine for order updates, and it was never built to sell.

Step by step: Shopify to WhatsApp in about 10 minutes

• 1. Connect your store. Install Port8 from the Shopify App Store and authorize it. Your products, variants, prices, and stock sync automatically and stay synced. This is the brain, and it takes about 5 minutes. WooCommerce, WordPress, and any other site work too.
• 2. Connect WhatsApp Business. In the Port8 dashboard, open Integrations and click Connect on WhatsApp Business. You log in with your Meta account, self serve, a few clicks. While you are there you can connect Instagram DMs and Messenger with the same login.
• 3. That's it. One brain, every channel. The same AI employee that answers your site chat now answers WhatsApp with the same knowledge and the same voice. The site widget stays your main stage, and no channel is a silo.

What it actually answers on WhatsApp

The questions your customers already send you at 11pm:

• "Which of these fits my skin type / my room / my kid?"
• "Is this in stock in medium? When would it arrive?"
• "What is your return policy on sale items?"
• "Where is my order?"

Sales questions get a recommendation from the live catalog. Support questions get resolved on the spot. And it never invents an answer: when it does not know, it says a human will follow up and collects the customer's details.

You stay in control of every conversation

This is the part store owners worry about most, and it is the part we built most carefully. You can jump into any conversation, from two places: the chat history in your Port8 dashboard, or natively inside your own WhatsApp app. The moment you send a message, the AI pauses and the thread is yours. When you are done, it picks the next customer back up. AI answers by default, you answer whenever you want.

Why put an agent on WhatsApp at all

Because the question is where the sale is. A store with someone answering questions converts several times better than a store that stays silent, which is the whole 2% versus 20% story. WhatsApp is simply where a growing share of those questions arrive, especially from mobile shoppers. Answering them in seconds, from your real catalog, is the same conversion mechanic as site chat, moved to the channel your customers already use.

What it costs

The WhatsApp, Instagram DM, and Messenger connections are included in every Port8 plan, together with the site chat widget and the bio link page. There is no per-channel add-on. Plans and a 7-day free trial are on the pricing page, and the full channel breakdown lives on the WhatsApp AI chatbot page.
