Why send notifications over WhatsApp instead of SMS?

WhatsApp messages support longer text, images, files and buttons, and customers read them where they already chat every day. Many businesses use WhatsApp for rich notifications and SMS as a fallback.

Is there an API for developers?

Yes — an HTTP API with API-key authentication for sending messages, media and templates from your own software, with full documentation in the client panel.

Can I send Bengali messages with attachments?

Yes. Bengali and English text, images, PDFs and other files are all supported, ideal for sending invoices and receipts.
