Without any information on the error you getting or why it's not working, I can't be certain what you need, but I have two working solutions that will hopefully help.
If you're sending from the browser:
function sendMgEmail(pFrom, pTo, pSubject, pText, mgApiKey){
const formData = new FormData();
formData.append('from', pFrom);
formData.append('to', pTo);
formData.append('subject', pSubject);
formData.append('text', pText);
const qXhr = new XMLHttpRequest;
const qMethod = 'POST';
const qUrl = 'https://api.mailgun.net/v3/{{YOUR_DOMAIN}}/messages';
qXhr.open(qMethod, qUrl);
qXhr.setRequestHeader('Authorization', 'Basic ' + window.btoa('api:' + mgApiKey));
qXhr.send(formData);
qXhr.onload = function() {
if(qXhr.status == '200' || qXhr.status == '201') {
console.log('email queued', qXhr.status, qXhr.responseText);
} else {
console.log('ERROR ', qXhr.status, qXhr.responseText);
}
}
}
If from a Nodejs application, the XMLHttpRequest approach does not seem to work:
First, refer to https://www.npmjs.com/package/mailgun.js?utm_source=recordnotfound.com#messages
Then, install form-data and mailgun.js
npm i form-data
npm i mailgun.js
Lastly, the code...
const FormData = require('form-data');
const Mailgun = require('mailgun.js');
exports.sendMgEmail(pFrom, pTo, pSubject, pText, mgApiKey) {
const mailgun = new Mailgun(FormData);
const mg = mailgun.client({username: 'api', key: mgApiKey})
mg.messages.create('{{YOUR_DOMAIN}}', {
from: pFrom,
to: pTo,
subject: pSubject,
text: pText
})
.then(msg => console.log(msg))
.catch(err => console.error(err));
}
