Don't settle for passive chatbots that only answer questions. Equip your AI agents to book appointments, generate payment links, query CRMs, and trigger backend webhooks live during conversations.
Action execution across Phone, WhatsApp & Web
Whether a customer asks on a phone call, in WhatsApp chat, or through your website widget, your backend tools execute with identical precision and security.
The agent executes the booking API while continuing conversational speech, holding caller engagement with natural filler words.

Tool Calling & Webhooks FAQs
How does latency impact tool calling during live phone calls?
Voice requires sub-second turn-around. ThinnestAI uses parallel tool execution and proactive speculative calling. When an API call is made, the voice agent naturally says 'One moment while I check our calendar...' so the conversation never feels laggy or robotic.
How are webhooks secured?
Every webhook request includes an HMAC-SHA256 signature header, mutual TLS support, and strict timeout boundaries. Your API credentials and headers are encrypted at rest with envelope encryption.
Can we define tools visually without coding?
Yes. In the ThinnestAI dashboard, you can define tools either by providing an OpenAPI / Swagger JSON spec, or by entering endpoint URLs, headers, and parameter definitions in our visual tool builder.
