Fill in your hours, your Twilio number and a test phone (your own mobile).\n2. Connect Twilio, Gmail and the AI model credentials.\n3. Copy the **Production URL** from the Webhook node. In Twilio, point your number's forwarding TwiML at it (see the page for the exact snippet), or have any phone system POST {\"from\",\"status\"} to it.\n4. While **testMode** is true, every text goes to your test phone, not the caller. Call yourself, let it ring out, check the text.\n5. Texting customers needs their permission and an opt-out.
