I'm just getting started with Vue and the use of APIs. On my VueJs component, I want to use this code that I retrieved from here Google Classroom API Javascript. I want to retrieve the lists of classrooms that I handle when I clicked a button and display them on my view template.

However, using this code results in numerous errors when attempted in my SynchButton.vue file inside methods. I also added the clientId and scope in my main.js file. I hope that you could all help me guys. Thank you all so much in advance!

I am threatened by Google to quit using the old (but very effective) "Google Sign-in" because it will be deprecated on 31 Mar 2023. It is fine, but when I go for the new "Sign in with Google", I find that there are no documents explaining how this new authorization flow can integrate with Google Sheet API.
Ironically, even in Google Sheet API's documentations, the demos there are all still based on the old "Google Sign-in". Can anyone provide demo cases of how to read and insert values into Google Sheet based on the new "Sign in with Google"?
The Google sheets api quickstart for javascript has been updated to use web authorization.
You dont want to use signin unless you are working with Authencation, for google sheets you need authorization. The new library splits these two concepts.

When I click Authorize, Google signs in, but when I refresh the page, it prompts me to sign in to Google once more. What can I do to stay signed in until the user signs out? Here I tried javascript calendar API to insert an event into Google Calendar.
I'm using the Google Calendar API and I'm trying to keep the user signed in when they reload the page but I'm having trouble with it. I can't find anything online about this.

Technically you can't stay signed in after the page reload - all state data is lost, so JS code have to redo all process of sign-in.
But to make life easier you can somehow save access token and use it to speed-up things after page reload. That's what Google lib should do behind scenes - save to cookies or something like that. And it looks like it fails to do so in your case, because of browser or Google security policy, some privacy tool, bug - there are many possible reasons. Did you check browser console for errors?

I believe your goal is as follows.
You want to create a new Google Document using Google Docs API with Javascript.
You have already been able to use Google Docs API.
In this case, how about the following modification?
Modified script:
First, please modify your scope from https://www.googleapis.com/auth/documents.readonly to https://www.googleapis.com/auth/documents.
And, please modify your script as follows.
From:
function printDocTitle() {
gapi.client.docs.documents.get({
documentId: '1Q0MGsSSqovVRiDadfnq9eCinoBnOuQn4hnh3-pOsbME'
}).then(function (response) {
var doc = response.result;
var title = doc.title;
appendPre('Document "' + title + '" successfully found.\n');
}, function (response) {
appendPre('Error: ' + response.result.error.message);
});
}
To:
function printDocTitle() {
gapi.client.docs.documents.create({
resource: {title: "sampleTitle"}
}).then(function (response) {
var doc = response.result;
var title = doc.title;
appendPre('Document "' + title + '" successfully found.\n');
}, function (response) {
appendPre('Error: ' + response.result.error.message);
});
}
When this script is run, a new Google Document with the title of "sampleTitle" is created to the root folder.

Therea are two buttons for sign in and for sign out.
Problem: this code doesn't work in firefox (when I click auth button, choose google account then nothing happens) and in chrome (I cant logout).
Maybe there is any error in this code?
How can I solve this problem?
In my console there are not any errors.
Thanks,
For the signing-out process try using GoogleAuth.disconnect(); to revoke the token which was mentioned here.
The calendar API sample is working as intended on my end. Make sure it's enabled in your Google Dev console and the localhost ports are indicated in your clientID

please reply me..........
You have to update your scope from https://www.googleapis.com/auth/classroom.courses.readonly to https://www.googleapis.com/auth/classroom.courses.
According to the document, courses.create requires the following OAuth scope:https://www.googleapis.com/auth/classroom.courses to work.
The scope https://www.googleapis.com/auth/classroom.courses.readonly is used for listing and getting data. If there is a need to create, update you have to use https://www.googleapis.com/auth/classroom.courses to gain full access to the API.
Hope this helps.
