How to retrieve an invoice with Quickbooks Online API using Java SDK and oAuth 2.0

How do I retrieve an invoice from Quickbooks Online using the Java SDK? I'm currently migrating from oAuth 1.0 to 2.0 and the library upgrades have removed the methods I had previously been using to retrieve an invoice in PDF format. The new libraries I'm using are:

  • oauth2-platform-api-6.0.2
  • ipp-v3-java-devkit-6.0.2
  • ipp-v3-java-data-6.0.2

Previously, I had been doing something like this:

OAuthConsumer consumer = new DefaultOAuthConsumer(consumerKey, consumerSecret);
consumer.setTokenWithSecret(accessToken, accessTokenSecret);  

String urlStr = String.format(
    "https://quickbooks.api.intuit.com/v3/company/%s/invoice/%s/pdf", realmId, invoiceId);

URL url = new URL( urlStr );
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Accept", "application/pdf");
connection.setUseCaches(false);

consumer.sign(connection);
connection.connect();

...but OAuthConsumer is gone now. Is there some replacement for this that I can use to sign the request, or alternatively is there someway to do it with the DataService object?

You can sign your request in the same way using oAuth2 with the OAuth2Authorizer object e.g. 

URL url = new URL(urlStr);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
OAuth2Authorizer oauth = new OAuth2Authorizer(accessToken);
oauth.authorize(connection);
