Questions

Asked & answered.

Still curious? Talk to a human.

Yes — completely free, no account and no credit card. You customize the button, copy the code and paste it on your site. It opens a WhatsApp chat with your number; nothing is billed.

No. The free button uses the standard wa.me click-to-chat link, so it works with any WhatsApp or WhatsApp Business number. The API is only needed if you later connect Sendiee to auto-reply with AI.

No. The widget is a single self-contained script under 6 KB gzipped with zero dependencies, loaded asynchronously. It renders inside a Shadow DOM, so it can never clash with your site’s CSS or JavaScript.

Enter your number, customize the look, copy the generated <script> tag and paste it just before the closing </body> tag of any page. It works on plain HTML, WordPress, Shopify, Webflow, Wix and any other site that lets you add custom code.

Yes. Set a pre-filled message with placeholders like {{page_url}} and UTM tags, and optionally add your Meta Pixel or GA4 ID to fire a conversion event in your own analytics whenever someone clicks.

The free button just opens WhatsApp so a human can reply. Connecting Sendiee adds an AI agent that answers instantly, qualifies leads, verifies payments and follows up automatically — across WhatsApp, Instagram and Messenger.
