eTermin

Let your customers book appointments through conversation, not forms

Customers want to schedule an appointment but hate filling out online forms. Your AI agent talks them through it, checks eTermin availability, creates the booking, and even applies a voucher, all within the chat. Bookings increase because the experience feels effortless.

Scheduling operations your agent handles live

Use Cases

Booking scenarios that reduce no-shows

Real examples of how conversational scheduling through eTermin increases bookings, reduces missed appointments, and keeps your calendar running smoothly.

After-Hours Appointment Booking for Clinics

A patient visits your clinic's website at 9 PM wanting to book a consultation. Your AI Agent checks eTermin working times, finds available slots for the next morning, and creates a new contact record for the patient. The appointment is booked and confirmed in the chat. The patient does not have to call during office hours, and your front desk arrives to a fully scheduled morning.

Service Selection for First-Time Customers

A customer contacts your spa asking about treatments but is unsure what to book. Your AI Agent retrieves the full service list from eTermin, describes each option with duration and pricing, and helps the customer choose. Once decided, the agent creates their contact and books the appointment. The customer goes from undecided to booked in a single conversation without visiting a separate booking page.

Promotional Voucher Distribution via Chat

You are running a holiday promotion and want to offer 20% off to engaged visitors. When a customer asks about pricing, your AI Agent creates a unique voucher in eTermin with a percentage discount and validity dates, then shares the code in the chat. The customer can apply it during checkout. Your promotions reach engaged prospects at the moment of highest intent.

FAQs

Frequently Asked Questions

How does the AI agent check available time slots in eTermin?

The agent calls the Get Working Times endpoint with a specific calendar ID. eTermin returns the defined working hours and available blocks for that calendar. The agent then presents open slots to the customer. Your buffer times, break periods, and calendar-specific rules are all respected.

Can the agent create contacts automatically when new customers book?

Yes. During the conversation, the agent collects the customer's first name, last name, and email. It then calls the Create Contact endpoint in eTermin to register them. This contact is linked to their appointment, so your booking records are always complete.

What authentication does eTermin require for the API?

eTermin uses HMAC-SHA256 signed requests. You provide your public API key, private secret key, and a randomly generated salt in the Tars dashboard. Each API request is signed with the private key and salt, ensuring secure communication. No OAuth flow is needed.

Does Tars store any of my eTermin appointment or contact data?

No. The agent queries eTermin in real time during conversations. Appointment details, contact records, service lists, and working times are fetched live from your eTermin account. Tars does not maintain a copy of your scheduling data.

Can the agent handle appointment cancellations and rescheduling?

Yes. For cancellations, the agent calls the Delete Appointment endpoint with the appointment ID. For rescheduling, it cancels the existing booking and creates a new one based on the customer's preferred time. The customer handles everything in the chat without calling your office.

Does the integration support multiple calendars for different staff or locations?

Yes. eTermin supports multiple calendars, and the agent can retrieve all calendars using the Get Calendars endpoint. When booking, the agent selects the appropriate calendar based on the requested service, staff member, or location, and checks working times for that specific calendar.

How is this different from eTermin's standard online booking widget?

The eTermin widget is a form-based booking page. Tars adds a conversational layer that guides customers through service selection, answers questions, and handles edge cases before booking. It also works on WhatsApp and SMS, not just your website, reaching customers wherever they prefer to communicate.

Can the agent create and distribute discount vouchers during conversations?

Yes. The Create Voucher endpoint lets the agent generate vouchers with custom codes, discount types (percentage or fixed amount), and validity periods. The agent can share the voucher code with the customer in the chat and even help them apply it to their booking.

“Powerful tool - and there's so much more still to explore!”
I love the flexibility of the TARS chatbot design tool. The ability to drop in a new gambit and easily de-link and re-link gambits before and after it saves HOURS of time lost if I had to regenerate from scratch. TARS stands out for its flexibility, consistent performance, and outstanding support.

“Best in class for lead generation”
TARS is an essential tool within our lead gen strategy. I started to use it a couple years ago, and the platform evolved to focus on results. You can integrate your Google Analytics, Facebook Pixel, and AdWords conversion tag to track results and measure your campaign. You can also integrate with Zapier, which opens a lot of possibilities. Compared with static landing pages, we have seen an increase in conversions and more engagement.

If you are building chatbots, you cannot go wrong with TARS. I have been with this company since their beginning. Seen how they have grown.
