costumize different whatsapp message for each page

Hi Starmilo ,

Thanks for reaching out to us! I hope that you had a great weekend.

You could perhaps duplicate your button and change the icons of the duplicates.
Then you can use the page rule feature to make the buttons show up on the pages you would like to show the button.

Let me know what you think of this.

Sorry I misunderstood the question.

Yes, you could also use the same method by duplicating the button then show it on the correct page using page rules to have a different pre-filled message in your WhatsApp button.

Or if the text that's different per page is already on the page, you could maybe use a Javascript button action instead and get that info from the page when the button is clicked.
This will make it so that you don't have to create multiple buttons in Buttonizer but you will need to add the info on the page instead. You will also need to understand Javascript a bit
