How do I send a thank-you message after a customer dines?

Type it in the chat while the 24-hour window is open. Later, on the API, it needs an approved template, and a general thank-you counts as a marketing message.

• Inside the 24-hour window, write freely. On the API, from 1 October 2026, each number gets 1,000 free replies a month, then pays utility rates.
• After 24 hours, the API allows only approved templates. Meta files a general thank-you under marketing: ₹0.8631 per delivered message in India.
• A thank-you with a discount is marketing too. Meta's own example is a thank-you for the last order with a percentage off the next one.
• A message about one specific order or visit that asks for feedback, with no promotion, can be approved as utility (₹0.115 in India).
• In the free Business app, save your thank-you as a quick reply. You can store up to 50.
