How the button works
The button opens a WhatsApp conversation with your chosen number and draft message. The visitor confirms sending in WhatsApp. The widget does not reply to messages, assign conversations or connect the WhatsApp API.
After publishing, open the page on a phone and computer. Check the country code and number, tap the button and check the draft message. If the icon is missing, check whether the editor kept the script and whether your site security policy allows tools.chatsac.com.
Frequently asked questions
Is the button free?
The generator and widget are free and include Chatsac Tools branding. Your website platform may restrict custom code based on its plan or your permissions.
Do I need the WhatsApp API?
No. The button uses a wa.me link to open WhatsApp. Automation, multiple agents and CRM connections require a separate service.
Does the button guarantee sales or send weekly reports?
There is no sales guarantee. The service records installation and click beacons, which do not prove that a message was sent. Weekly email reports are not available yet.
