Frequently asked questions
What is the difference between a Lead and a Prospect?
In Zenvia Conversion, a Lead is an initial contact entry. Once a lead is processed or created via the API, it becomes a Prospect in your CRM pipeline.
Can I start a WhatsApp conversation with a new number?
Yes, but you must use an approved HSM template to initiate a new conversation. Free-text messages can only be sent to active conversations within the 24-hour window.
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.
