How do I auth in google api with my credentials or special generated id and password?

I want to get all my events from my personal calendar. I have tried for hours all kind of auth types: I did successfully auth with callback, where I should login to my google account and then google redirects back to my website. - but this is not what I need. Also I have tried with default credentials, and on my surprise, I don't have access to my calendar, what kind of logic is this.

Basically, how its working for me in Spotify: in Spotify it is possible to generate client id and password in my account. After that I send HTTP with base64(client:password) in my header from my code and receiving token, which I use to query some entities.

But in google API I didn't find such solution. Maybe someone could advice how to authenticate?

You could use the Google client library for PHP. It's marked beta, but I found it easy to use and it works just fine for simple Calendar use cases.

I put a working example out on GitHub.

If you would rather code directly against the OAuth 2.0 APIs, I'd recommend checking out the Google Developers OAuth 2.0 Playground.

  • Select the Calendar API v3 at step 1.
  • At step 3, click List possible operations and select List Events. Replace {calendarId} with your gmail.com email address.

This allows you to observe the auth flow, starting with the redirect back to your application after the user authenticates and grants permissions with Google:
