One Inbox for WhatsApp + Website Chat: The 2026 Setup Guide
Here is a setup we see constantly: a live chat tool — tawk.to, Crisp, something similar — on the website, and the WhatsApp Business app on someone's phone. Two inboxes, two histories, two places to look for context. Most small teams arrive there honestly — each tool was free and solved half the problem. The trouble: customers do not respect the split — they ask on web chat, follow up on WhatsApp, and expect whoever answers to know the whole story. In 2026 the fix is a single platform: web chat on your site via the free Click to AI Chat plugin, WhatsApp through the official Cloud API, with every conversation tagged and threaded in one team inbox and one AI knowledge base answering both. The plugin is free, the account is free with no credit card, and the web chat widget with AI replies is free forever — the only optional charge is a one-time $10 per domain to remove the small "Powered by The Tech Pad" link, and automated WhatsApp messages pay only Meta's per-message rate.

The Two-App Problem
One real conversation shows the pain. A visitor opens your web chat: "Do you have the 12-inch in stock?" Your chat agent confirms it. An hour later the same customer messages on WhatsApp: "The 12-inch you said was in stock — my order number is #4821, can you check it?" The person holding the phone has no idea what "you said" refers to. No shared history, no context — so the customer re-explains, or decides you are too disorganized to buy from.
That is not a failure of either tool. tawk.to is genuinely good at free human chat with no seat limits on its core plan, and the WhatsApp Business app suits one phone and one owner. The problem is architectural: a website-chat product on one side, a phone app on the other, and the customer in the middle. Every reply that slips through the gap, every repeated question, every context search across two apps is a cost you are already paying.
What One Inbox Means
One inbox changes the daily workflow in four ways:
- One queue, two channels. Every conversation lands in one list with a clear channel tag — WhatsApp or Web Chat — so agents always know the channel.
- One contact history. Both threads belong to the same contact record — one view, no copy-paste.
- Context that travels with the chat. Web chat conversations carry visitor context (page, pages visited, source/UTM, country, device), so a cold "is this in stock?" arrives with its story.
- One set of alerts. New chats and handoffs trigger email alerts, so a lead never waits for someone to remember a second app.
A shared inbox does not make your team bigger — it removes the overhead that made a small team feel smaller.
How the Setup Works
Your website talks to The Tech Pad through the plugin; WhatsApp talks to it through the official Cloud API. Everything lands in the same inbox:
| Channel | How it connects | Where it lands |
|---|---|---|
| Website chat | Free Click to AI Chat plugin embeds the Web Chat widget; you paste a publishable key | Team inbox, tagged Web Chat, with visitor context attached |
| Your Business number connects through the official WhatsApp Cloud API | Team inbox, tagged WhatsApp | |
| AI answers | One knowledge base built in AI settings powers Auto-Pilot | Replies on both channels, in the same conversations |
Web chat works standalone first — put the widget up today, connect WhatsApp later, and both channels land in the same queue.
Setup: One Inbox in Six Steps
- Install the plugin. In WordPress go to Plugins → Add New → Upload Plugin, choose the techpad-click-to-ai-chat.zip file you downloaded above, then Install Now and Activate.
- Connect your key. Create a free account at thetechpad.com/wa/, copy your publishable key from Web Chat settings, paste it into Settings → Click to AI Chat, and allowlist your domain. Visitors never need an account.
- Connect your WhatsApp number. The platform provisions your WhatsApp Business Account (WABA) via Meta's embedded signup — no Meta developer console, and your number and templates stay yours.
- Invite your team — everyone works the same queue from their own login.
- Set the greeting and business hours. Two starter templates — a web chat greeting and an after-hours auto-reply:
Hi {{1}}! Thanks for reaching out — ask us anything about products, orders or delivery. In a hurry? The green WhatsApp icon takes you straight to WhatsApp, and it is the same conversation on our side.
Thanks for your message, {{1}}. Our team is offline right now and will reply here when we're back — or message us on WhatsApp at {{2}} for the fastest answer. Same team, same conversation.
- Switch on AI Auto-Pilot. Write your answers once in AI settings — FAQs, policies, prices, product info — and Auto-Pilot serves them on both channels, with handoff keywords and draft-by-default approvals, as documented in the Click to AI Chat plugin guide.
One AI, One Knowledge Base
Instead of training one bot for web chat and another for WhatsApp, write your answers once and Auto-Pilot serves both channels. The shipping answer a visitor gets at 11 pm matches the one a customer gets on WhatsApp at the same hour, because both come from the same content.
Keep the honest framing: the AI answers from your knowledge base, not a general-purpose brain, so it never invents a policy you did not write. Visitors can always ask for a human or trigger a handoff keyword, and the full history goes with the handoff. If your content does not cover a question, the AI says so instead of guessing, and that conversation reaches your team.
Team Workflow in the Inbox
Day to day, the team inbox is where the merge shows. Agents open one screen: WhatsApp messages and web chat conversations, each tagged by channel, each with contact history and visitor context attached. Handoffs carry their history, attachments arrive as files, and email alerts flag new chats instantly.
What the One-Inbox Setup Costs
Free to start, with the honest line where Meta draws it:
- Plugin: free. Account: free, no credit card. Web chat widget and AI replies: free forever. The shared inbox: free.
- The only optional charge is the one-time $10 per domain to remove the small "Powered by The Tech Pad" link.
- WhatsApp outbound automation — scheduled or triggered messages, not replies inside an active conversation — pays only Meta's per-message rate, roughly ₹0.10-0.30 per utility message in India. That rate is Meta's; The Tech Pad does not mark it up.
Contrast that with a live chat tool that charges separately for AI (tawk.to's AI Assist is paid, with a small free message allowance, per its site) while WhatsApp stays on a phone with no shared queue — two "free" tools that cost you time every day.
FAQ
How do I get WhatsApp and website chat into one inbox? Use a platform that runs both channels, like The Tech Pad: connect your WhatsApp Business number (official Cloud API) and put its web chat widget on your site with the free Click to AI Chat plugin. WhatsApp messages and web chat conversations appear in the same team inbox with channel tags — one queue instead of two apps.
Why is running chat and WhatsApp separately a problem? Two tools means two logins, two histories and replies that slip through the gap — a customer asks on web chat, then follows up on WhatsApp, and the agent has no context. One inbox keeps the full thread, contact and history together regardless of channel, and one AI knowledge base answers both.
Do I need a WhatsApp Business API account for this? For the one-inbox setup, yes — The Tech Pad provisions your WABA through Meta's embedded signup during onboarding, so you don't touch the Meta developer console. Web chat works standalone first; WhatsApp connects later and both land in the same queue.
Can agents tell which channel a message came from? Yes — every conversation in The Tech Pad inbox carries a clear channel tag (WhatsApp or Web Chat), and visitor context for web chat includes the page they were on, pages visited, source/UTM, country and device.
What does the one-inbox setup cost? Free to start, no credit card: the Click to AI Chat plugin is free, the web chat widget and AI replies are free forever, and the shared inbox is free. Outbound automated WhatsApp messages pay only Meta's per-message rate (roughly ₹0.10-0.30 per utility message in India).
Merge Both Channels — Free
Stop paying for the two-app split in lost context and missed replies. The plugin is free, the account is free with no credit card, and web chat with AI answers is free forever — the only optional charge remains the one-time $10 per domain to remove the small "Powered by The Tech Pad" link. Download techpad-click-to-ai-chat.zip, create your free account at thetechpad.com/wa/, and put both channels in one queue this afternoon. Comparing first? Our tawk.to alternatives for 2026 shows how this stacks up against the chat tools you may already run.
