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 Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
