Credentials Error When Integrating Google Drive With

Google Drive API - Invalid Credentials

The result of the link below is an Authorization code.

https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&client_id=735795831119-kcpkamhiaojavqrt67mti7thcaa6ce87.apps.googleusercontent.com

You need to exchange it to https://accounts.google.com/o/oauth2/token to generate an Access Token:

curl \
--request POST \
--data "code=[Authentcation code from authorization link]&client_id=[Application Client Id]&client_secret=[Application Client Secret]&redirect_uri=urn:ietf:wg:oauth:2.0:oob&grant_type=authorization_code" \
https://accounts.google.com/o/oauth2/token

The result of the curl above is something like this:

{
  "access_token": "access token here",
  "expires_in": 3599,
  "refresh_token": "refresh token here",
  "scope": "https://www.googleapis.com/auth/drive",
  "token_type": "Bearer"
}

Now you have the access token, you can paste it in the code below alongside with your API key.

curl \
  'https://www.googleapis.com/drive/v3/files?corpora=user&q=createdTime%20%3E%20%272021-11-23T12%3A00%3A00%27&key=[YOUR_API_KEY]' \
  --header 'Authorization: Bearer [YOUR_ACCESS_TOKEN]' \
  --header 'Accept: application/json' \
  --compressed

Note:

Make sure you enable the Drive API in GCP
Application Client Id and Application Client Secret can be found after you created an OAuth 2.0 Client ID in GCP.

Google Drive API Service Account Authentication fails

I have solved the problem..... I was wrong the authentication token

code: 401, message: Invalid Credentials -Google drive connection error

problem was been in the code -> wrong way to grab the refresh token, the correct code is:

 } else {
                
                try{
                    $token = json_decode($accessToken, true);
                    $this->client->setAccessToken($token);
              

                if ($this->client->isAccessTokenExpired()) {
                         if ($this->client->getRefreshToken()) {
                 $this->client->fetchAccessTokenWithRefreshToken($this->client->getRefreshToken());
    }
               
                    }
             
                }catch(Exception $e){
                    
                    $accessToken = null;
                    $auth_url = $this->client->createAuthUrl();
                 

                }

Now app works perfetly, nomore disconnection!

Authentication problem with google drive API in python

I found the answer here
You need to add these 2 SCOPES together:

SCOPES = ['https://www.googleapis.com/auth/drive.appdata','https://www.googleapis.com/auth/drive.file']

Google Drive API - Invalid service account credentials

Invalid service account credentials

Normally means that the key fine you are using is invalid. You need to create a service account key file.

If you open the json key file it should look something like this

{
  "type": "service_account",
  "project_id": "Redacted-305109",
  "private_key_id": "Redacted",
  "private_key": "-----BEGIN PRIVATE KEY-----Redacted---END PRIVATE KEY-----\n",
  "client_email": "Redacted@testapikey-305109.iam.gserviceaccount.com",
  "client_id": "Redacted",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/Redacted-305109.iam.gserviceaccount.com"
}

how to create a service account key file

Docs: google-api-nodejs-client#service-account-credentials

const {google} = require('googleapis');

const auth = new google.auth.GoogleAuth({
  keyFile: '/path/to/your-secret-key.json',
  scopes: ['https://www.googleapis.com/auth/cloud-platform'],
});
