Use Cases

Conversations that reach every channel

See how businesses extend AI agent conversations into SMS, voice, and postal channels using ClickSend, ensuring customers receive the right message on the right medium.

Appointment Confirmations via SMS in Real Time

A patient books a dental appointment through your website chatbot. Your AI Agent collects the preferred date, confirms availability, and then triggers ClickSend to send an SMS with the appointment date, time, and office address to the patient's mobile. The patient receives a text within seconds, and your front desk never has to pick up the phone to confirm bookings.

Multichannel Order Updates Across Geographies

An international e-commerce customer asks 'Where is my package?' Your AI Agent retrieves the shipping status, then sends a ClickSend SMS update to the customer's local number in their country, formatted with the tracking link and estimated delivery window. Customers in 190+ countries get timely updates on the channel they actually check, their phone.

Physical Mail Triggered by Digital Conversations

A financial services customer requests a formal account statement. Your AI Agent gathers their verified address, generates the statement content, and dispatches a physical letter through ClickSend's postal API with address detection and formatting. The customer gets an official document by mail while the entire request was handled in chat, no human processing required.

FAQs

Frequently Asked Questions

Which messaging channels can the AI agent use through ClickSend?

The agent can send SMS, MMS (with media attachments), voice messages using text-to-speech, fax documents, transactional emails, and physical post letters through ClickSend's unified API. Each channel is triggered based on the conversation context and your configured rules.

Can the agent send messages to international phone numbers?

Yes. ClickSend supports messaging to 190+ countries. The agent uses the appropriate country code and ClickSend routes through direct carrier connections. You can configure country-specific sending rules using the Global Sending settings, and the agent can retrieve supported country lists and pricing before sending.

How does the agent manage opt-outs and compliance?

The agent can check opted-out contacts within ClickSend lists before sending messages and remove opted-out recipients using the dedicated endpoint. ClickSend handles carrier-level compliance. You configure opt-out rules in your ClickSend account, and the agent respects them automatically during every send operation.

Does Tars store the SMS messages or phone numbers sent through ClickSend?

No. Tars passes the message content and recipient details to ClickSend's API in real-time and does not retain copies. Your message history, delivery receipts, and contact data are stored in your ClickSend account only. Tars acts as the trigger, ClickSend handles delivery and storage.

Can the agent calculate messaging costs before sending a campaign?

Yes. ClickSend provides price calculation endpoints for SMS, MMS, and postal campaigns. The agent can call these before dispatching to estimate total cost based on recipient count, destination countries, and message length. This allows cost approval workflows before committing to large sends.

How is this different from using ClickSend's web dashboard to send messages?

The ClickSend dashboard requires someone to log in, compose a message, select recipients, and hit send. With Tars, messages are triggered automatically by conversation events. A customer books an appointment, and the SMS goes out. A lead qualifies, and the follow-up text fires. No manual steps, no dashboard logins.

Can the agent send physical postal letters through ClickSend?

Yes. The agent uses ClickSend's Post Letters API to send physical mail. It can detect and format addresses from raw text, calculate postage costs, and dispatch letters including return address configuration. Useful for legal notices, account statements, or welcome packets that require a physical document.

What authentication does ClickSend require for the Tars integration?

ClickSend uses Basic authentication with your account username and API key. You find both in your ClickSend dashboard under API Credentials. Enter them in the Tars tool configuration, and all ClickSend channels become available to your AI agent immediately. No OAuth flows or token refreshes needed.

“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.

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.

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. I have tested a lot of bots, but this one is still the best out there. We use WhatsApp a lot for our business.
