Frequently asked questions
What is the difference between a session message and a template message?
Session messages can only be sent if the user has messaged you in the last 24 hours. Template messages are pre-approved by WhatsApp and can be used to initiate a conversation at any time.
How do I see the approved templates in my account?
Use the list_message_templates query. Your agent will retrieve the complete list of pre-approved WhatsApp templates available in your Wati dashboard.
Can I retrieve the last messages from a specific customer?
Yes! Use the list_chat_history tool and provide the customer's WhatsApp number. The agent will return the message history for that specific conversation.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
