Google Contacts samples are FOUR YEARS out of date (using OAuth V1)

[TheLimey]

While trying to learn how to use the Google Contacts API from python, I followed links from here:

https://developers.google.com/google-apps/contacts/v3/?csw=1#running_the_sample_code

...to this repo.

I worked out that gdata requires TLS Lite, and that TLS Lite needs m2crypto to stop it from erroring. However, having cleared all those hurdles, I found that your sample scripts are using OAuth V1 which YOU deprecated FOUR years ago!!! ....the four years is according to this page:

https://developers.google.com/identity/protocols/AuthForInstalledApps

Important: ClientLogin has been officially deprecated since April 20, 2012 and is now no longer available. Requests to ClientLogin will fail with a HTTP 404 response. We encourage you to migrate to OAuth 2.0 as soon as possible.

Please follow you own advice and upgrade the sample scripts to OAuth 2.0 as soon as possible.

Thank you =)

Now it does not work at all: just a 404 error on login. The docs just have a comment "Auth here" with no example of how to connect the gdata api to the oauth2 authorization. Here is an example for others who arrive here looking for information:

Thanks @rocketraman , I was exactly looking for that.
The repository samples should be updated at some point ...

The Calendar example does not work too.
Below is the output from latest Ubuntu 19.04:
