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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
