Google GMail API - users.messages.import() not in INBOX Why? - gmail

Question

I am importing directly a message using the GMAil API
When I look in to the GMail user account ( browser GMail app) I can see th message received in All Mails , but not in the INBOX
Google GMail API states : Users.messages.import()
Imports a message into only this user's mailbox, with standard email delivery scanning and classification similar to receiving via SMTP. Does not send a message
As the message is laying there I cannot get it from a Mail.app (OSX) or Outlook (MS) since it's not considered as a new message ... is that true ? anyway to solved this issue ?
Here is the function I am using to import a new message
unction gMailInserMessage (sender_name, sender_email, msg_text) {
// Create a new JWT client using the key file downloaded from the Google Developer Console
const jwtClient = new google.auth.JWT(
postoffice_key.client_email,
null,
postoffice_key.private_key,
_.values(config_key.scopes.postoffice),
config_key.contact_email // subject (or sub) impersonated user
);
return jwtClient.authorize().then(tokens => {
// Obtain a new gmail client, making sure we pass along the auth client
const gmail = google.gmail({
version: 'v1',
auth: jwtClient
});
const subject = '🤘 CONTACT 🤘';
const utf8Subject = `=?utf-8?B?${Buffer.from(subject).toString('base64')}?=`;
const messageParts = [
'From: ' + sender_name + '<' + sender_email + '>',
'To: Contact Box <' + config_key.contact_email + '>',
'Content-Type: text/html; charset=utf-8',
`Subject: ${utf8Subject}`,
'',
'A new contact message just to say hello.',
'So... <b>Hello!</b> 🤘❤️😎'
];
const message = messageParts.join('\n');
// The body needs to be base64url encoded.
const encodedMessage = Buffer.from(message)
.toString('base64')
.replace(/\+/g, '-')
.replace(/\//g, '_')
.replace(/=+$/, '');
//Make an authorized request to import a User Messages
return gmail.users.messages.import({
userId: 'me',
resource: {
raw: encodedMessage
}
});
}).then(res => {
// console.log('RES: ', res)
return res.data;
});
}
Here is the Response I get from the requets

Solved all the issues raised upon trying to use a Firebase function to handle a site Contact Form.
1 - Using GCP, in my Firebase project, I created a Service Account named 'postoffice', with Domain Wide Delegation, downloaded the credentials in JSON format into functions/postoffice-key.json
2 - I enabled GMail API for the project
3 - I handle the scopes and email addresses in another functions/config-key.json
4- In My GSuite Admin console ( Security>Advanced settings > Manage API Client Access , I added the clientId from the postoffice-key.json file with the authorized scopes
5 - I wrote a new Firebase HTTPS Function : newContactMessage()
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const { google } = require('googleapis');
const path = require('path');
const _ = require('lodash');
var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
// KEY FILES
const postoffice_key = require('./postoffice-key.json');
const config_key = require('./config-key.json');
function gMailInsertContactMessage (sender_name, sender_email, msg_text) {
// Create a new JWT client using the key file downloaded from the Google Developer Console
const jwtClient = new google.auth.JWT(
postoffice_key.client_email,
null,
postoffice_key.private_key,
_.values(config_key.scopes.postoffice),
config_key.admin_email // subject (or sub) impersonated user
);
return jwtClient.authorize().then(tokens => {
// Obtain a new gmail client, making sure we pass along the auth client
const gmail = google.gmail({
version: 'v1',
auth: jwtClient
});
const subject = '🤘 CONTACT 🤘';
const utf8Subject = `=?utf-8?B?${Buffer.from(subject).toString('base64')}?=`;
const messageParts = [
'From: "Administrator" <' + config_key.admin_email + '>',
'To: "Contact Box" <' + config_key.contact_email + '>',
'Reply-To: "' + sender_name + '" <' + sender_email + '>',
'Content-Type: text/html; charset=utf-8',
'MIME-Version: 1.0',
`Subject: ${utf8Subject}`,
'',
'<h2>MESSAGE</h2>',
'<p>' + msg_text + '</p>'
];
const message = messageParts.join('\n');
// The body needs to be base64url encoded.
const encodedMessage = Buffer.from(message)
.toString('base64')
.replace(/\+/g, '-')
.replace(/\//g, '_')
.replace(/=+$/, '');
//Make an authorized request to import a User Messages
return gmail.users.messages.send({
userId: 'me',
resource: {
raw: encodedMessage
}
});
}).then(res => {
// console.log('RES: ', res)
return res.data;
});
}
// FIREBASE HTTP FUNCTIONS ==================
exports.newContactMessage = functions.https.onRequest((req, res) => {
const sender_name = 'Mrs Jenny Doe'
const sender_email = 'jenny.doe#example.com'
const sender_msg = 'Hello, how are you overthere ?'
gMailInsertContactMessage(sender_name, sender_email, sender_msg).then((res) => {
return { status: 200, infos: res };
}, error => {
return {status: error.status, infos: error.message};
}).then(response => {
return res.send(response);
}).catch(console.error);
});
test request:
curl -v https://us-central1-myproject.cloudfunctions.net/newContactMessage
Firebase function returns :
{"status":200,"infos"
{"id":"163a5738080e3ee9","threadId":"163a5738080e3ee9","labelIds":["SENT"]}}
In the Mail.app on my computer, I can see the From: being the project owner ( Administrator ) the To: being the Contact box ( contact#mysite.org and the Reply-To: being the Contact Form sender email... easy to reply..!
and the message content !
Hope this help... ( should I edit the question title ? )
