WhatsApp API for car dealers: test drives, service bookings and renewals
A dealership playbook for WhatsApp: qualify model enquiries, book test drives, remind owners about service and renewals, and send the invoice when the vehicle is ready.

The problems WhatsApp solves for car and two-wheeler dealerships
Model enquiries go cold within hours
Leads from OEM portals, Click-to-WhatsApp ads and walk-ins pile up at month end. A buyer who asks for an on-road price on a Saturday evening and hears back on Monday has usually visited the dealer across the road.
Test drives get booked but not attended
Sales consultants book test drives on phone calls and in personal WhatsApp chats. Nobody confirms the slot the day before, so demo vehicles sit idle while other buyers wait.
Service retention drops after the free services
Once the free service coupons are used, owners drift to roadside garages. The workshop has the odometer reading and last service date but no reliable way to remind owners at the right time.
Workshop status calls tie up service advisors
"Is my car ready?" calls arrive all afternoon. Advisors stop work to check the job card, and the owner still has to come in to see the invoice before paying.
Conversations live on personal phones
When a consultant leaves, their chats, quotes and follow-ups leave with them. The dealership has no record of what was promised to which buyer.
How dealers use WhatsApp from enquiry to service
The WhatsApp API for car dealers covers the whole ownership cycle on one showroom number: a chatbot qualifies model enquiries, test drives are booked against real demo-vehicle availability, service reminders go out on the due date, and the vehicle-ready message carries the invoice. It suits multi-brand and single-brand dealers, two-wheeler showrooms and independent workshops that see enough enquiries to need more than one phone. A single-outlet garage with ten customers a day may be fine on the WhatsApp Business app; read Business app vs API if you are unsure.
If you are new to the platform, start with what the WhatsApp Business API is. Every message you send first, outside a customer's 24-hour window, must be an approved message template.
Message templates to get approved first
| Template name | Category | Sample |
|---|---|---|
test_drive_confirm | Utility | Hi {{1}}, your test drive of the {{2}} is booked for {{3}} at {{4}}. Sample: Rohan, Venue 1.2 Petrol, 18 Oct 11:00 am, Sai Motors Baner |
test_drive_reminder | Utility | Reminder: your test drive of the {{1}} is tomorrow at {{2}}. Please carry your licence. Sample: Venue 1.2 Petrol, 11:00 am |
service_due_reminder | Utility | Hi {{1}}, your {{2}} ({{3}}) is due for service on {{4}}. Sample: Meera, Activa 6G, MH12 AB 4521, 25 Oct |
vehicle_ready_invoice | Utility | Hi {{1}}, your vehicle {{2}} is ready. Invoice {{3}} for ₹{{4}} is attached. Sample: Arjun, MH14 CD 7788, SM-WS-20431, 6,842 |

new_model_launch | Marketing | Hi {{1}}, the new {{2}} arrives this Saturday. Book an early test drive. Sample: Kunal, Creta facelift |
The first five describe a booking, a vehicle or a policy the customer already has, so they fit the utility category. Keep them free of offers: adding "and get 10% off accessories" to a service reminder makes it marketing. The template guide covers variables and approval in detail.
Chatbot flow outline
- Click to WhatsApp Ads and New Message triggers start the sales bot; a Match Keyword trigger on "service" starts the workshop bot.
- Ask Question with a list: New car, Service booking, Insurance renewal, Talk to someone.
- Sales branch: Ask Question for model, variant, city and timeline, each saved with Save Variable Value to custom fields; Send Message with the brochure PDF.
- Working Hours checks if the showroom is open; in hours, Assign to Agent routes to the sales department of the right outlet; out of hours, the bot offers a test drive slot.
- Test drive: the Native Calendar app (added through Add Automation App) fetches open slots for the Test drive event type, the customer picks one, and the booking is created.
- Service branch: Ask Question for registration number, then the Native Calendar app books a workshop slot under a Periodic service event type.
- Send Conversion Event (Lead Submitted or Qualified Lead) reports qualified ad leads back to Meta.

- Payments → Payment Gateways: Razorpay or PayU for WhatsApp payments, or PhonePe payment links, so owners pay the workshop invoice before pickup.
Illustrative ROI
Illustrative only; replace with your own numbers. A workshop sends service-due reminders to 1,200 owners a month. If the reminder brings back 60 owners who would otherwise have gone to an outside garage, at an average paid-service ticket of ₹4,500, that is ₹2,70,000 of workshop revenue. From that, subtract Meta's charges for 1,200 utility templates plus follow-up messages (Meta gives 1,000 free service messages per number per month, then charges them), and your platform subscription. Current Meta rates are on our WhatsApp API pricing explainer. Measure the return-to-workshop rate for reminded owners against a month with no reminders before you trust any figure.
Getting started
Set up the number with the WhatsApp Business API setup guide, then build the sales bot using how to build a chatbot. For the booking side, the appointment reminders use case shows the reminder timing in detail. Agencies that handle digital marketing for several dealerships can run this playbook for all of them under their own brand through the partner program.
Use cases with example messages
Model enquiry and on-road price request
A chatbot answers the first message from an ad or the website, asks model, variant, fuel type, city and purchase timeline, and saves them to custom fields before assigning the lead to the right showroom.
Reply inside the 24-hour window
Business: Hi Rohan, thanks for asking about the Nexa-style compact SUV. Which variant are you considering? [Petrol MT] [Petrol AT] [CNG]
Example message Test drive confirmation and reminder
When a test drive is booked, a utility template confirms the slot with the showroom location. A second reminder the evening before carries Confirm and Reschedule buttons.
utility template
Business: Hi {{1}}, your test drive of the {{2}} is booked for {{3}} at {{4}}. Please carry your driving licence. [Confirm] [Reschedule] Sample: Rohan, Venue 1.2 Petrol, 18 Oct 2026 11:00 am, Sai Motors, Baner Road, Pune
Example message Periodic service due reminder
A repeating campaign or workflow sends a reminder 7 days before the service due date, with a button to book a workshop slot through the chatbot.
utility template
Business: Hi {{1}}, your {{2}} ({{3}}) is due for its periodic service on {{4}}. Tap Book slot to choose a time at our workshop. [Book slot] Sample: Meera, Activa 6G, MH12 AB 4521, 25 Oct 2026
Example message Vehicle-ready message with invoice
When the job card is closed, the owner receives a vehicle-ready template with the invoice as a PDF document and a payment request, so they can pay before arriving.
utility template
Business: Hi {{1}}, your vehicle {{2}} is ready for pickup. Invoice {{3}} for ₹{{4}} is attached. You can pay online or at the counter. Sample: Arjun, MH14 CD 7788, SM-WS-20431, 6,842
Example message Motor insurance renewal reminder
For customers whose policy was arranged through the dealership, a renewal reminder goes out 30 and 7 days before expiry, and a licensed staff member handles questions about cover.
utility template
Business: Hi {{1}}, the motor insurance policy for {{2}} expires on {{3}}. Reply RENEW and our insurance desk will share the renewal quote. Sample: Priya, MH12 XY 9087, 2 Nov 2026
Example message Launch and exchange-offer campaigns
New model launches, festive exchange offers and accessory deals go as marketing templates only to contacts who opted in to offers, segmented by the model they own or enquired about.
marketing template
Business: Hi {{1}}, the new {{2}} arrives at Sai Motors this Saturday. Book an early test drive and get a free accessories kit worth ₹{{3}}. Reply STOP to opt out. Sample: Kunal, Creta facelift, 8,000
Example message
A rollout playbook
Move every consultant onto one number
Connect the showroom number under Channels → All Channels and give consultants logins in the shared inbox. If the number is already on the WhatsApp Business app, coexistence lets you keep using the app while the API runs alongside.
Build the qualification bot first
Capture model, variant, city, timeline and exchange vehicle on the first chat. These five fields decide which consultant gets the lead and what they say first.
Put test drives on a calendar
Create a Test drive event type with the number of demo vehicles as bookings per slot, so the bot never books two buyers into one car at the same time.
Import the service base
Import owners with registration number, model, last service date and next due date as custom fields. This is the list your service reminders run on.
Automate the workshop close-out
Trigger the vehicle-ready template from your DMS through the API or a workflow when the job card closes, with the invoice PDF attached.
Add campaigns after the utility flows run cleanly
Once reminders and confirmations are steady and the quality rating is healthy, start launch and exchange campaigns to opted-in owners only.
Compliance notes
- Keep separate consent for service updates and for offers. An owner who gave a number for the job card has not agreed to receive launch campaigns.
- Do not promise finance approval, exchange values or discounts that are subject to OEM or lender conditions; state that terms apply and give the conditions in chat.
- Insurance renewal advice about cover, add-ons or claims should come from staff licensed under your IRDAI-registered arrangement, not from the chatbot.
- Share registration documents and invoices only with the registered owner's number; confirm identity before sending documents to a new number.
- Give every automated flow a path to a person, and honour STOP replies across sales and service campaigns.

Frequently asked questions
Can one WhatsApp number serve both the showroom and the workshop?
Yes. Use one number with a menu at the start and departments in the inbox, so sales consultants and service advisors each see their own chats. Larger groups with separate outlets often use one number per outlet instead, so the display name matches the location.
Is a service due reminder a marketing or utility message?
A reminder about a scheduled service for a vehicle the customer owns is usually utility. If it adds offers, discounts or accessory promotions, Meta treats it as marketing, so keep promotions in a separate template.
Can we stop two buyers being booked into the same demo car?
Yes. In the Native Calendar, set bookings per slot to the number of demo vehicles available for that model. Once a slot is full, the chatbot stops offering it.
Can customers pay the workshop invoice on WhatsApp?
Yes. Send the invoice PDF with a payment request through Razorpay or PayU WhatsApp payments, or a PhonePe payment link. Card details are never typed into the chat.
Our consultants already use WhatsApp on their own phones. What changes?
Chats move to a shared inbox on the dealership number, so history stays with the business when someone leaves. Consultants can still reply from the mobile app, and managers can see response times per person.
