Error while accessing Access Token

[singhal425]

Hi,

I'm getting (java.lang.String) Cannot extract an access token. Response was: {"error_type": "OAuthException", "code": 400, "error_message": "Matching code was not found or was already used."} while accessing access token.

The piece of code I've written to get the access token:

InstagramService service = new InstagramAuthService().apiKey(this.instagramClientId) .apiSecret(this.instagramClientSecret).callback(this.instagramCallbackUrl).build(); String authorizationUrl = service.getAuthorizationUrl(); Verifier verifier = new Verifier(authorizationUrl); try { return service.getAccessToken(verifier); }catch(OAuthException authException) { authException.getMessage(); }

Here, the verifier which is passed is not the code after redirection but the complete authorization URL which I think is the reason of error mentioned at the top. In the verifier, I should be passing the authorization code which I will be getting after hitting https://api.instagram.com/oauth/authorize/?client_id=<CLIENT_ID>&redirect_uri=<CALLBACK_URL>&response_type=code but it asks for credentials which nowhere we're passing. So, I wanna know is there any piece of code written code which I can use to generate the Authorization code or I need to write separate code for that?

I've got the same issue wiht the example. I try to use Java Lib but i've got the Insta page where i have to fill username/password info to get the code afterwords...
Some has resolve this point?

I didn't find resolution of that problem. So, as a workaround I generated the access token (since there's no expiry of it) and passed access token to fetch account data.
