connectToSalesJet.js

// USE THIS FUNCTION TO CONNECT ANY EXTERNAL APP TO SALES JET:

async function submitToSalesJet(api_key, event_name, email, first_name, last_name) {
      try {
        const response = await fetch("https://sj-api.com/externalapp/track", {
          method: "POST",
          headers: {
            "Content-Type": "application/json",
            Authorization: api_key // YOUR API KEY GOES HERE
          },
          body: JSON.stringify({
            event_name: event_name, // YOUR EVENT NAME GOES HERE,
            contact: {
              email: email, // Your email field 
              first_name: first_name, //Your first name field
              last_name: last_name // Your last name field
              phone_number: phone_number // Your phone number field
              custom_attributes: {
                  "dc7627c8-b33f-eb11-a9a9-c26375d3e59f": data.subject, // Custom attribute UUID goes here
                  "451d9d75-b43f-eb11-a9a9-c26375d3e59f": data.message  // Custom attribute UUID goes here
              }    
            },
          }),
        });
  
        // YOU CAN GET HOLD OF THE RESPONSE OBJECT FROM SALES JET TO CHECK IF THE CONNECTION WAS SUCCESSFUL:
        console.log(response);
    }
    

This function uses native fetch to connect any external app to Sales Jet. Feel free to refactor this with any AJAX util you like.
