Unable to get access token

0 Votes
I believe I've followed the docs, but am getting a 400 status code when trying to get an access token.  I've created the API code and call the following URL to get the auth code:   

// https://api.cc.email/v3/idfed?client_id=22c<redacted>2c3b&redirect_uri=https%3A%2F%2Flocalhost&response_type=code&scope=account_read+account_update+contact_data

private HashMap< String , String > headersMap = new HashMap<>();

public static void main( String[] args ) throws IOException {

ConstantContactUtilities constantContactUtilities = new ConstantContactUtilities();


public ConstantContactUtilities() {

// apiKey and clientId are the same field. Stupid ConstantContact uses both terms for the same thing
String apiKey = "22c<redacted>2c3b";
String clientSecret = "RPd<redacted>jCQ";

String credentials = apiKey + ":" + clientSecret;
String authorization = "Basic " + Base64.getEncoder().encodeToString(credentials.getBytes());

headersMap.put( "Authorization" , authorization );

public void getAuthCodeFromAccessTokenAndRefreshToken() throws IOException {

String authCode = "Bo090<redacted>8NQAEt";

HttpUtilities httpUtilities = HttpUtilities.getInstance();
String url = "https://idfed.constantcontact.com/as/token.oauth2?code=" + authCode +
HttpResponse httpResponse = httpUtilities.doPost( url , headersMap , new HashMap< String , String >() );
System.out.println( httpResponse.getStatusLine() ); <-- 400 status code

What am I doing wrong?
