After you installed the MacroDroid app, it is time to install the macros, first use the following link to download the macro file.
Now that you have the macro file downloaded, click on the 'Export/Import' tool on the 'Home' page of the Macrodroid app. On the next screen click on the button under 'Import' (circled in the picture below) and select the downloaded macro file.

Note: The variable name is case sensitive and needs to be spelled EXACTLY how it is in the image above to work.

Make sure everything is similar to the above picture. Now you can access your private link, click the copy symbol (Circled in green in the picture) to copy it to your clipboard.
Now with your private link copied, go to the next page using the link down below, paste it in the box and submit. This will generate a unique public link which you can copy and send to other people. Your public link will take them to a web page where they can submit links to be opened on your phone through the macros.
