What are connections?

Connections (also called tools) are external services your agent can invoke during a phone call. When a caller asks a question that requires live data — like looking up an address, checking availability, or creating a booking — the agent calls the connected tool and uses the result in its response.

​
How tools work

  1. You configure a tool with its API endpoint and parameters.
  2. You link the tool to your agent.
  3. During a call, the AI model decides when to invoke the tool based on the conversation context.
  4. The tool is called, and the result is fed back into the conversation.

​
Available tools

Google Maps

Look up addresses, get directions, and find nearby locations.

Custom API tools

Connect any REST API endpoint as a tool your agent can use.

​
Linking tools to an agent

  1. Go to your agent’s settings.
  2. Open the Tools tab.
  3. Browse available tools or create a custom tool.
  4. Click Add to link a tool to the agent.
  5. Configure any required settings (API keys, endpoints).
Tools are invoked automatically by the AI model when relevant. You can control this behavior with the tool choice setting — see AI models.

​
Tool execution

When a tool is invoked during a call:
  • The agent pauses briefly while the tool executes.
  • The tool’s response is returned to the agent as context.
  • The agent incorporates the result into its spoken response.
  • Tool calls are logged in the call transcript.
Tools that take longer than 10 seconds to respond may cause noticeable pauses in the conversation. Keep your API endpoints fast.
