<div id="bkmrk-interactive-call-to-">## Interactive Call-to-Action URL Button Messages

<div><span>Updated: Nov 3, 2025</span></div><div>WhatsApp users may be hesitant to tap raw URLs containing lengthy or obscure strings in text messages. In these situations, you may wish to send an interactive call-to-action (CTA) URL button message instead. CTA URL button messages allow you to map any URL to a button so you don't have to include the raw URL in the message body.</div><div>![](https://support2.chatarchitect.com/uploads/images/gallery/2026-04/embedded-image-6gc5fu9y.png)</div><div id="bkmrk-request-parameters"><div id="bkmrk-request-parameters-1"><div>### Request parameters
