Contacts API and OAuth2

[Rebecca Miller-Webster]

Hi,

I'm successfully authenticating via OAuth2 and am able to see user info via: 

https://www.googleapis.com/oauth2/v1/userinfo?access_token=XXXX''

However, if I try:

https://www.google.com/m8/feeds/contacts/default/full?access_token=XXXX

I get a 401 Token Invalid - AuthSub token has wrong scope

When I am redirected to authenticated, it says the app wil "Manage contacts," so I am pretty sure the scope is correct.  However, I'm obviously not using AuthSub.

Is OAuth2 not available at all for the Contacts API?

Thanks,

Rebecca

Hello Rebecca,

Sorry about the delay in getting back to you! I can assure you that Contacts API does support OAuth 2.0 but you might have to specify the token in the request header:

GET https://www.google.com/m8/feeds/contacts/default/full

Authorization: Bearer <OAUTH_2_0_ACCESS_TOKEN>

You can try this behavior on OAuth Playground.

Best,

Alain

Hi Alain,

Thanks for getting back to me.  

When I try it out in the OAuth2 playgroud with Step 3 hitting 'https://google.com/m8/feeds/contacts/default/full', I get:

Something bad happened: 500 HTTP error. Message: {"success": false, "error": "An error occured while processing the request, please retry"}

I did change the header in my code to Authorization: Bearer XXXX but I am still getting a 401 error with the message: "Token invalid - AuthSub token has wrong scope"

I do see a 302 redirect on https://accounts.google.com/o/oauth2/approval which I wasn't seeing before.  

Any ideas?

Thanks,

Rebecca

The below codes work for me, see if you are doing something different

    private static final String SCOPE = "https://www.google.com/m8/feeds";

    GenericUrl shortenEndpoint = new GenericUrl("https://www.google.com/m8/feeds/contacts/default/full/");
    HttpRequest request = rf.buildGetRequest(shortenEndpoint);
    GoogleHeaders headers = new GoogleHeaders();
    headers.setContentType("application/x-www-form-urlencoded");
    headers.setAuthorization("OAuth " + accessToken);
    request.setHeaders(headers);   
    request.getHeaders().set("GData-Version", "3.0");
    HttpResponse shortUrl = request.execute();
