get data from api in nodemailer node.js config

Question

I'm trying to create a sender config nodemailer node.js, that is fetched dynamic data coming from API, example:

let transporter = nodemailer.createTransport({
host: fromAPI,
port: fromAPI,
secure: fromAPI,
auth: {
    user: fromAPI,
    pass: fromAPI
}});

"fromAPI" it's dynamic data coming from api

I tried to build from axios but it doesn't work, any suggestions?

axios.get('http://localhost:4500/api/email_config', {
        headers: {
            'Content-Type': 'application/json',
            Authorization: `Bearer mytoken`,
        },
    }) 
 .then(function (response) {
    console.log(response.data); 
})
.catch(function (error) {
    console.log(error);
});
