Clients write to your WhatsApp number — the assistant answers, offers free slots and books appointments straight into your calendar.
A Meta (Facebook) Business account and a real phone number for the assistant that is NOT registered in the WhatsApp app (a spare SIM or even a landline works). If the number is already used in WhatsApp, delete that account first: WhatsApp → Settings → Account → Delete account. Everything runs through the official WhatsApp Cloud API — no phones left online, no gray-zone tools.
Sign in at developers.facebook.com, create an app of type Business and pick the “Connect with customers through WhatsApp” use case. On the app dashboard open Customize use case → Quickstart, select your business portfolio and press Continue — Meta creates a WhatsApp Business Account with a free TEST number. The test number is only for a quick trial: it can’t be renamed and only messages 5 pre-approved recipients. Your real number is added in the next step.
Open WhatsApp → API Setup and press “Add phone number” (the same flow lives in WhatsApp Manager → Phone numbers). Enter the display name clients will see instead of the bare number (it must match your business — Meta reviews it), pick a category, enter the number and confirm the SMS or voice code. When the number appears in the list, copy its Phone number ID.
The token from API Setup expires in 24 hours — fine for testing, useless for production. In Business Settings (business.facebook.com/settings) open Users → System users, add a system user with the Admin role, press Assign assets and grant it your app and your WhatsApp account. Then Generate token: pick the app, set expiration to Never, tick whatsapp_business_messaging and whatsapp_business_management, and copy the token.
In the dashboard open AI assistant → Settings → WhatsApp card, paste the real number’s Phone number ID and the permanent token, press Connect. Klendr verifies them with Meta on the spot — a typo won’t save.
This step happens in the Meta app, not in Klendr. In the use case menu open Configuration → Edit and paste the Callback URL and Verify Token — copy both FROM the WhatsApp card in your Klendr dashboard and paste them here in Meta. After “Verify and save” a Webhook fields section appears below on the same page — find the “messages” row and press Subscribe (or press Manage and toggle “messages” on). That single field delivers client messages; the rest can stay off.
Message your number from any phone — with a real number ANY client can write, no test-recipient lists. The assistant greets you, answers questions about services and prices and offers real free slots. Every chat is visible in AI assistant → Chats, where you can always take over.
We help with the Meta part — the Klendr part takes two minutes.
