Most small businesses start WhatsApp customer support the same way: they download the WhatsApp Business App, set up a profile, and start replying from a shared phone or tablet. It works — for a week, maybe a month. Then the team grows, two people need to reply at the same time, messages get missed, and there is no way to see what happened in a conversation when the person who handled it is offline. The free WhatsApp Business App was never designed for team-based support. It is designed for individual business owners.
This guide explains the right way to set up WhatsApp for customer support — using the WhatsApp Business API, connected to a helpdesk inbox, with proper routing and automation from day one.
WhatsApp Business App vs WhatsApp Business API: what is the difference?
| Feature | WhatsApp Business App | WhatsApp Business API |
|---|---|---|
| Cost | Free | Via helpdesk platform (e.g. $39/seat/mo on Delyt) |
| Multiple agents | No (1 device only) | Yes — unlimited agents |
| Helpdesk integration | No | Yes — native inbox integration |
| Automation and routing | No | Yes — AI routing, auto-replies |
| Message templates | Basic | Full template library |
| Analytics | Very limited | Full reporting in helpdesk |
| Suitable for teams | No | Yes |
The WhatsApp Business App is suitable for sole traders and micro-businesses where one person handles all customer communication from a single device. The moment you have more than one person handling support, or you want automation, routing, or analytics, you need the WhatsApp Business API.
What you need before you start
Setting up WhatsApp Business API requires three things that you need to prepare before you can connect to a helpdesk. Getting these in order before starting the helpdesk setup saves time and avoids the most common points of friction.
- A registered business: Meta requires business verification as part of the WhatsApp Business Account approval process. You will need your business registration number, address, and possibly additional documentation depending on your country. This is a one-time verification.
- A Facebook Business Manager account: this is Meta's business management platform where you will create and manage your WhatsApp Business Account. If you run Facebook or Instagram ads, you may already have one.
- A dedicated phone number: the phone number you register with WhatsApp Business API cannot currently be registered with regular WhatsApp or WhatsApp Business App. Use a dedicated business number — a VoIP number works fine. You will receive a verification code via call or SMS.
Step-by-step: connecting WhatsApp to your helpdesk
- 1Create a Facebook Business Manager account at business.facebook.com if you do not already have one. Add your business details and complete any identity verification steps Meta requests.
- 2In Business Manager, navigate to "WhatsApp Accounts" under the Business Settings menu. Click "Add" to create a new WhatsApp Business Account and fill in your business display name, business category, and description.
- 3Add a phone number to your WhatsApp Business Account. Click "Add phone number", enter the number you want to use for WhatsApp, and complete the verification (call or SMS code). Note: this number must not be registered with any WhatsApp account already.
- 4Open your helpdesk platform (for Delyt: go to Settings → Channels → WhatsApp) and click the connection flow. You will be prompted to log in with your Facebook Business Manager account and select the WhatsApp Business Account you created.
- 5Authorise the helpdesk to manage your WhatsApp account. This grants permission for the helpdesk to send and receive messages on behalf of your WhatsApp number.
- 6Configure your routing rules: set up which agents or AI agents handle incoming WhatsApp conversations. Add an auto-reply for out-of-hours messages using an approved WhatsApp message template.
- 7Test by sending a WhatsApp message to your business number from a personal WhatsApp account. The message should appear in your helpdesk inbox within seconds.
Meta verification timeline
Business verification on Facebook Business Manager typically takes 1 to 3 business days. The WhatsApp Business Account itself is usually approved within minutes once the Business Manager is verified. Plan for a total setup timeline of 2 to 5 business days from start to first live conversation.
How conversations from WhatsApp land in your inbox
Once connected, every inbound WhatsApp message appears in your helpdesk inbox alongside email, live chat, and social messages. Agents see the customer's WhatsApp display name, their message history, and any previous interactions they have had across other channels (if the helpdesk links conversations by contact). The conversation is treated like any other support ticket: it gets assigned, routed, tracked, and resolved through the same workflow as everything else.
From the customer's side, nothing changes. They send a WhatsApp message to your business number from their personal WhatsApp app. They see your business profile with your display name and logo. Replies come from the same number. They do not know or need to know that the response came through Delyt or any other platform — they just experience faster, more organised support.
Automating WhatsApp replies with AI
Once WhatsApp is connected to your helpdesk, you can apply the same AI automation that handles email and chat tickets to WhatsApp conversations. Common queries — order status, return policies, opening hours, product questions — can be handled automatically by AI agents without human intervention. The AI reads the WhatsApp message, searches your knowledge base for the relevant information, and sends a reply directly to the customer through the WhatsApp channel.
In Delyt, you configure AI automation through the AI Studio. You assign AI agents to specific conversation types, set confidence thresholds (so the AI escalates to a human when it is not sure), and monitor resolution rates through the analytics dashboard. The same AI agents that handle email tickets handle WhatsApp tickets — there is no separate configuration per channel.
