ClickSend uses username and API key based authentication. Your end users connect their ClickSend account through Truto's connected-account flow, and Truto handles credential storage and injection into every request — you never touch the API key. ### Can I isolate each of my customers into their own ClickSend environment? Yes. Truto exposes ClickSend's subaccount endpoints, so you can programmatically create a subaccount per tenant, fetch usage with the account usage endpoint, regenerate API keys, and delete subaccounts on churn. ### Which communication channels are supported? All of ClickSend's channels are covered: SMS, MMS, voice, email, fax, letters, and postcards — including their campaign, template, history, and receipt endpoints. ### Can I show users the cost of a campaign before sending it? Yes. Every send-capable channel has a matching calculate-price tool (SMS, MMS, voice, email, fax, letters, postcards, and campaign variants), so you can render an accurate cost preview in your UI before dispatching. ### How do I handle inbound messages and delivery receipts? You can list inbound SMS, mark them as read individually or in bulk, and pull SMS/voice/fax/email receipts. For event-driven flows, ClickSend's inbound and receipt automations can be created and managed via the corresponding automation tools to route events to your own webhook endpoints. ### Does the integration support physical mail address validation? Yes. Before sending letters, you can call the address-detection endpoint to validate a postal address, upload the PDF asset via the upload endpoint, and then trigger the letter or postcard send. ### Can users manage sender IDs and phone numbers from my app? Yes. Truto exposes tools to search and purchase numbers, register them, manage alpha tags, configure default senders, and handle own-number verification — enough surface area to build a full sender-identity settings page. ## Related reading - [Connect ClickSend to ChatGPT: Manage SMS, Voice, and Physical Mail](https://truto.one/blog/connect-clicksend-to-chatgpt-manage-sms-voice-and-physical-mail/) — Learn how to connect ClickSend to ChatGPT using a managed MCP server.
