Error: invalid_client when following five minute quick start for PHP?

0 like 0 dislike
233 views

I am trying the "Five minute quick start" ( https://developers.google.com/drive/ ) and have followed all instructions up to step 4 "Run the sample". (I have changed the client ID and secret in the sample php code - I've followed the instrictions in text and watched the video to be sure I didn't miss anything). When I run the script from command line, I am indeed provided with a link to follow - such as this:

https://accounts.google.com/o/oauth2/auth?response_type=code&redirect_uri=http%3A%2F%2Flocalhost&client_id=938259907386.apps.googleusercontent.com&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&access_type=offline&approval_prompt=force

But when I point my browser there (logged into Google console) I consistently get an error:

Error: invalid_client ... and the details are:

response_type=code
scope=https://www.googleapis.com/auth/drive
redirect_uri=http://localhost
access_type=offline
approval_prompt=force
client_id=938259907386.apps.googleusercontent.com

I've tried deleting the client ID and re-creating, but I keep running into the same error. Any suggestions on what could be going wrong? Thanks.

It's strange, if I simply replace the client ID in this URl with one of my test client ID it works correctly. Could you take a screenshot of your client ID credentials in the APIs Console and upload it online please? (just make sure your hide the secret... or simply delete that credentials afterwards) PS: you are not the forst one to repport this so something must be wrong somewhere...
Not sure how to upload screenshot - but here's a copy/paste from Console:Client ID for installed applications Client ID: 938259907386.apps.googleusercontent.com Client secret: *** Redirect URIs: urn:ietf:wg:oauth:2.0:oob localhost
Issue on our side! We'll keep you updated!
Just wanted to let you know we're aware of the issue and working to resolve it
Not working for me yet, though the interaction has changed. Now I get an allow/deny page and I allow. It then redirects me with a URL like this: localhost/?code=4/… ... and when I try to use parts of the URL in answer to the prompt "Please enter the auth code:", I get fatal errors [Google_authException - Google_OAuth2.php:113]
