(Javascript How to use a function result as a parameter in another function [duplicate]

I’m currently trying to write a script to be embedded in a HTML file that:

1. Calls an API for a ticket
2. Uses the ticket in a subsequent function to display a dashboard

I’m kinda new to Javascript and learning as I go, but I’m getting a bit lost on this one 🙂

Function1 below shows my efforts to store the ticket as a variable. However, when I try to use the ticket in Function2, it appears that the API call hasn’t finished yet.

How can I make Function2 wait for Function1 to complete before processing?

Function1

function getTix() {
    return new Promise(function (resolve) {
        axios.get(api_url)
            .then(response => {
                resolve(response.data.ticket);
                console.log(response.data.ticket);
                myticket = response.data.ticket;
            })
            .catch(error => console.error(error));
    });
}

Function2

function showDashboard() {
    const dash_div = document.getElementById('displaydash');
    const dash_url = "https://server.com/" + myticket;
    
    viz = new Viz(dash_div, dash_url);
}
