The builder is included free with your Fast2SMS account. You pay only standard per-message WhatsApp charges, with no platform fee.<\/p>\n<h3>Do I need to know coding?<\/h3>\n<p>No. The builder is drag and drop. The only technical block is the optional API request, and your developer can set that one up in minutes.<\/p>\n<h3>Can the bot send images and PDFs?<\/h3>\n<p>Yes. Media blocks send images, documents and more. List menus and buttons make replies one-tap easy.<\/p>\n<h3>What happens when the bot cannot answer?<\/h3>\n<p>Set a fallback message, or hand the chat to a human agent in the Live Chat inbox. The customer never hits a dead end.<\/p>\n<h3>Can it work with my existing WhatsApp Business number?<\/h3>\n<p>Yes. Connect your existing number with coexistence and keep using your app while the bot handles incoming chats.<\/p>\n<h3>Can I send bulk messages too?<\/h3>\n<p>Yes, same account.
