How do I use Google's “Simple API Access key” to access Google Calendar info (PHP)?

Question

I\'m trying to use the Google API v3 to access one google calendar and according to the documentation here : http://code.google.com/apis/calendar/v3/using.html#intro and her

Answer 1

I got to this thread when trying to do the same today. Although this is way late, but the answer is YES, there is actually simple API key for those apis that does not need user authorizations, and the official client library support this.

The api library do this by Options, which is key, value pair.

Take the example of get information of a given youtube video, you would use this api: https://godoc.org/google.golang.org/api/youtube/v3#VideosListCall.Do

To use api key, simply make a type that implements the CallOption interface, and let it return the api key:

type APIKey struct {
}

func (k *APIKey) Get() (string, string) {
    return "key", "YOU API KEY HERE"
}

Then when calling the API, supply the APIKey to it:

youtube, err := youtube.New(&http.Client{})
call := youtube.Videos.List("snippet,contentDetails,statistics").Id(id)
rsp, err := call.Do(opt)

This way, you can construct the youtube client with the vallina http client, rather than oauth client, and enjoy the simple api key.

The first answer said you can use http GET directly, but then you will need to handle the errors and parse the result yourself.

Answer 2

You cannot access your calendar information using API Key. API keys (or simple API acess key) are not authorized tokens and can only be used for some API calls such as a Google search query etc; API keys will not let you access any user specific data, which I am assuming is your objective through this calendar application.

Also, from what I see in your code, you are creating a client object which is going to use OAuth 2.0 authentication and hence you are getting authentication error messages.

Answer 3

There is no such a thing called Simple API Access key.

Normally OAuth 2.0 is used for authorization. But since you have your reason not to use it.

• If you want to use OAuth1.0 for authorization. You need an API key in Simple API Access section on the API Access page.
• If you want to use username & password login instead of OAuth, you can refer to ClientLogin, but this is not recommanded.

See below link which is helpfull to you. The Google API Client Library enables you to work with Google APIs such as Analytics, Adsense, Google+, Calendar, Moderator, Tasks, or Latitude on your server, in the language of your choice.

(i know this is an old question but i would've been glad if someone gave a real answer here so i'm doing it now)

I came on the same problem, Simple API access is not well documented (or maybe just not where i searched), but using the Google API Explorer i found a way to get what i need, which is in fact pretty straightforward. You don't need specific lib or anything : it's actually really simple.

In my case i simply needed to search a keyword on G+, so i just had to do a GET request:

https://www.googleapis.com/plus/v1/activities?query={KEYWORD}&key={YOUR_API_KEY}

Now, for a calendar access (see here), let's pretend we want to fetch access control rules list. We need to refer to calendar.acl.list which give us the URI :

https://www.googleapis.com/calendar/v3/calendars/{CALENDAR_ID}/acl?key={YOUR_API_KEY}

Fill in the blanks, and that's pretty much all you need to do. Get a server key (API Access submenu), store it somewhere in your project and call it within URIs you're requesting.
