We should use a different API then. The point of this example is to illustrate 3-legged OAuth, and it's the only example we have for that.

Also, the path in examples/index.php needs to be updated

[grant]

I've updated examples/index.php as mentioned.

To resolve the linked bug, would you like to either:

• Keep this sample that uses a discontinued API
  or
• Delete this sample

For showing OAuth, perhaps we can cross link the G Suite samples which use OAuth:
https://github.com/gsuitedevs/php-samples

There are ~12 OAuth samples there.

Is there a third option of updating it to use another service? I only took a quick glance, but it looks like there is only a single insert call.

More than happy to link to one of the gsuitedevs samples!

[grant]

I added a link in the examples/ folder to the G Suite samples.

The docs seem to show an example of OAuth with Drive:
https://github.com/googleapis/google-api-php-client#authentication-with-oauth

So I'm not sure exactly why there's the comment of we should be using a different API as Drive already shows OAuth.

@bshaffer Please review.

@grant tests are failing. Change this line to look for 8 instead of 9.

[grant]

Done.
That's a super fragile test...
