# WhatsApp Business. From your agent. Source: https://corespeed.io/integrations/whatsapp Connect WhatsApp Business to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent checks which message templates Meta has approved, reads delivery status, and sends text, template and interactive messages from your business number. It acts on your own WhatsApp Business Account, and every send is a separate call that approvals can hold. ## Set up an agent Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)` It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect WhatsApp Business after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up ## Pick the right template. Before you send Outside the 24-hour reply window, WhatsApp accepts only approved templates. Have your agent check what Meta approved and show you the message first. You ask your agent: "Check which of our WhatsApp templates are approved. Pick one for a shipping notice and show me the message. Do not send it." It calls CoreSpeed: - `whatsapp__get_phone_numbers`: ok, 361 ms - `whatsapp__get_message_templates`: ok, 488 ms - `whatsapp__get_template_status`: ok, 302 ms It reads from: WhatsApp Business. ### Template check: Use order_shipped. It is approved as a utility template, so you can send it outside the 24-hour window. **Message preview** - Hi {{1}}, your order has shipped. It arrives on {{2}}. **Do not use** - delivery_delay was rejected. Edit it before you submit it again. - winter_sale is still pending review. _Illustrative templates · Fictional data · Nothing sent_ All connectors: https://corespeed.io/docs/connectors ## Know the template.

No. It connects a WhatsApp Business Account through Meta's Cloud API. It sends from your business number, not from a personal WhatsApp account. ### Why does my agent need a template? WhatsApp allows free-form messages only within 24 hours of the customer's last message. Outside that window, you must send an approved template. ### Will my agent message customers on its own? Only if you let it. Every send is a separate tool call, and approvals can hold it for a person. How approvals work: https://corespeed.io/solutions/agent-approvals ### Do I have to switch agents? No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once. ### Can my agent access every account in our organization? No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private. ### Does this work without connecting an account? No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data.
