## Why isn't my WhatsApp message being delivered? WhatsApp has a 24-hour customer service window. Recipients only receive messages within 24 hours of their last message to you. To message outside this window, use a template message. ## Why is my WhatsApp connection failing with "Missing required fields"? Ensure all required fields are provided when initiating the connection. See the [WhatsApp authentication details](https://docs.composio.dev/toolkits/whatsapp#authentication-details). ---
