Need help integrating webhook with existing script

For a while now, I've been using a script to help create various folders on my hard drive based on the types of projects I'm working on. In short, it asks me about the artist's name, year, song/album name, and type of project, and then creates the corresponding folders based on those details.

I'd now like to update it so that I can create a new project inside of Samply based on the artist name. To do so, I figured I'd need to use a webhook with Zapier to integrate it with Samply. That said, I've never used webhooks before so I think that's the solution. I just have no clue how to code that in. Any suggestions?

the following is my webhook URL: https://hooks.zapier.com/hooks/catch/1603543/2dwpxpx/

The following is my existing macro script:

// Set the root directory to the desktop
let rootDirectoryPath = "/Volumes/Rocksteady/Pro Tools Sessions";

// Ask user for the artist's name
const artistName = sf.interaction.displayDialog({
    prompt: "Please enter the artist's name",
    title: "Artist Name",
    defaultAnswer: "",
    buttons: ["Ok", "Cancel"],
    defaultButton: "Ok"
}).text;

// Ask user for the year
const year = sf.interaction.displayDialog({
    prompt: "Please enter the year",
    title: "Year",
    defaultAnswer: "",
    buttons: ["Ok", "Cancel"],
    defaultButton: "Ok"
}).text;

// Ask user for the album name
const albumTitle = sf.interaction.displayDialog({
    prompt: "Please enter the album title",
    title: "Album Title",
    defaultAnswer: "",
    buttons: ["Ok", "Cancel"],
    defaultButton: "Ok"
}).text;

// Ask user for the song title
const songTitle = sf.interaction.displayDialog({
    prompt: "Please enter the song title",
    title: "Song Title",
    defaultAnswer: "",
    buttons: ["Ok", "Cancel"],
    defaultButton: "Ok"
}).text;

// Define popup the options
const projectTypes = ["Mixing", "Mastering"]

// Popup window with option selection
const projectType = sf.interaction.popupSearch({
    items: projectTypes.map(projectType => ({
        name: projectType,
    })),
}).item.name;

// Project Folder Name and path
const projectFolderName = `${artistName}`;
const projectFolderPath = `${rootDirectoryPath}/${projectFolderName}`;

// Create Project Directory
sf.file.directoryCreate({ path: projectFolderPath });

if (projectType === "Mixing") {
    
    // Create Sub Folder named "To Mix"
    sf.file.directoryCreate({ path: `${projectFolderPath}/${year}/${albumTitle}/${songTitle}/To Mix` });
    sf.file.directoryCreate({ path: `${projectFolderPath}/${year}/${albumTitle}/${songTitle}/Reference Tracks` });

    //Add script for making pro tools session here.

} else if (projectType === "Mastering") {

    // Create render folders
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/44.1k Renders` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/44.1k Renders/${songTitle}_24441_WAV_V1` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/44.1k Renders/${songTitle}_16441_WAV_V1` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/48k Renders` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/48k Renders/${songTitle}_2448_WAV_V1` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/96K Renders` });
    sf.file.directoryCreate({ path: `${projectFolderPath}//${year}/${albumTitle}/${songTitle}/To Master` });
}

sf.file.open({path:projectFolderPath});
