Short answer: Clinics and diagnostic centres in India use WhatsApp for five things: booking appointments, sending reminders, sharing reports, asking for Google reviews after a visit, and recalling patients for follow-ups. On the WhatsApp Business API, appointment and report messages are utility templates at about ₹0.115 each, and replies inside 24 hours of a patient’s message are service messages. Because health details are sensitive personal data, get clear consent, send reports only to the patient’s own verified number, and keep promotional messages separate.

Five WhatsApp flows for clinics
| Flow | Message type | What it does |
|---|---|---|
| Appointment booking | Service (patient messages first) | Patient picks a service, doctor and slot by tapping buttons |
| Reminders | Utility template | A reminder the day before and a few hours before, with a reschedule button |
| Reports ready | Utility template | Tells the patient the report is ready, with a secure link or PDF |
| Review request | Utility or marketing, depending on wording | A short thank-you with your Google review link after the visit |
| Follow-up recall | Utility for a booked follow-up; marketing for general check-up offers | Reminds patients when a check-up or test is due |
1. Appointment booking
A patient messages from your website, Google profile or a Click-to-WhatsApp ad. An automatic reply asks which service they need, shows available timings as buttons, and confirms the slot. Your front desk sees every booking in a shared inbox and can step in for anything unusual. The chatbot side is explained in WhatsApp chatbot for business.
2. Reminders that cut no-shows
Send a reminder the day before and again a few hours before, with buttons to confirm or reschedule. A rescheduled appointment is far better than an empty slot.
3. Sharing reports safely
Lab and scan reports are health data. Under India’s DPDP Act, treat them as sensitive personal data:
- Send only to the phone number the patient registered with, and confirm it at registration.
- Get consent to receive reports on WhatsApp, and record it.
- Prefer a secure link with a short expiry, or a PDF with a password the patient knows, over an open file.
- Never send one patient’s report in a chat with someone else, including family, unless the patient has agreed.
Consent rules for WhatsApp are covered in DPDP Act and WhatsApp consent.
4. Asking for Google reviews
After a visit, send a short thank-you with your direct review link. Ask every patient, not only happy ones, and never offer discounts for reviews. Google bans both. Templates are in how to get more Google reviews.
5. Follow-up recalls
For patients with a follow-up the doctor scheduled, a reminder is a utility message. General check-up packages and health camp offers are marketing, need marketing consent, and cost more per message. Keep the two clearly separate in your templates.
What does it cost?
| Message | Meta charge (before 18% GST) |
|---|---|
| Reply inside 24 hours of a patient’s message | ₹0.115; providers report the first 1,000 a month per number are free |
| Utility template (reminders, reports) | ₹0.115 |
| Marketing template (offers, health camps) | ₹0.8631 |
A clinic sending two reminders for 300 appointments a month uses about 600 utility messages, roughly ₹69 before GST. Your platform plan is extra. Full rates are in WhatsApp Business API pricing in India.
What clinics should avoid on WhatsApp
- Promoting prescription medicines. WhatsApp’s commerce rules don’t allow selling them.
- Diagnosing or giving treatment advice in chat. Book a consultation instead.
- Sending offers to patients who only agreed to receive appointment messages.
- Running the clinic’s WhatsApp on a staff member’s personal phone.
Setting it up
You need the WhatsApp Business API on your clinic’s number (see how to get the WhatsApp Business API), approved templates for reminders and reports, and a shared inbox for the front desk. Adwix Connect includes the booking chatbot, templates, broadcasts and a team inbox in one dashboard.

Frequently asked questions
Can a clinic send lab reports on WhatsApp?
Yes, with the patient’s consent and only to their registered number. Health data is sensitive, so a secure link or password-protected PDF is safer than an open file.
Are WhatsApp appointment reminders free?
No. On the WhatsApp Business API, reminders are utility templates, charged at about ₹0.115 each plus GST. Replies to patients within 24 hours of their message are service messages, and providers report the first 1,000 a month are free.
Can patients book appointments on WhatsApp automatically?
Yes. A WhatsApp chatbot can show services and available slots as buttons and confirm the booking, with the front desk able to take over any chat.
Can a clinic send health camp offers on WhatsApp?
Yes, to patients who agreed to receive promotional messages. These are marketing templates, which cost more and need separate consent from appointment messages.
