Hello Pesce,

Thank you for reaching out to us.

You can use placeholder %appointment_cancel_url% in the Notifications section, this is a programmatically generated URL, and if you want to create a hyperlink to this URL, this needs to be added as a placeholder, not a direct URL.

More about Custom Notifications in Amelia you can find here: https://tmsplugins.ticksy.com/article/17674/.

Here is also the list of Amelia's placeholders with explanations: Notification Placeholders

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.

Have a nice day!

You're welcome, Pesce,

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.

My apologies if I already asked this before, but may I ask you for a small favor if you don’t mind? 

Can you, please, leave a review on the Lite version of Amelia if you have an account at wordpress.org and have a couple of minutes? No need to write any specific text.

If it's not too much of a trouble, an additional review on Capterra would be greatly appreciated!

It’d mean a lot to us, and as a token of our appreciation, we would like to offer you a $10 credit for SMS notifications.

Thanks in advance.
