Hi.
When I use the code locally, it works well, but when I try using it online,
I get this error: Looks like your application is not configured to use
OAuth2 properly. Required OAuth2 parameter RefreshToken is missing.
I think this is caused by not adding the online domain to the "Authorized
links" somewhere in the configuration. I remember putting the localhost
link somewhere there, but I cannot find it now.
I am using Targeting Idea Service.
Here's my code:
[HttpGet]
public IEnumerable<string> Get(string kword)
{
var user = new AdWordsUser();
using (TargetingIdeaService targetingIdeaService = (
TargetingIdeaService)user.GetService(AdWordsService.v201802.
TargetingIdeaService))
{
// Create selector.
TargetingIdeaSelector selector = new TargetingIdeaSelector
();
selector.requestType = RequestType.IDEAS;
selector.ideaType = IdeaType.KEYWORD;
selector.requestedAttributeTypes = new AttributeType[] {
AttributeType.KEYWORD_TEXT,
AttributeType.SEARCH_VOLUME,
AttributeType.AVERAGE_CPC,
AttributeType.COMPETITION,
AttributeType.TARGETED_MONTHLY_SEARCHES,
AttributeType.IDEA_TYPE,
};
// Set selector paging (required for targeting idea
service).
Paging paging = Paging.Default;
selector.paging = paging;
// Create related to query search parameter.
var relatedToQuerySearchParameter = new
RelatedToQuerySearchParameter { queries = new String[] { kword } };
var searchParameters = new SearchParameter[] {
relatedToQuerySearchParameter };
//searchParameters.Add(relatedToQuerySearchParameter);
var page = new TargetingIdeaPage();
selector.searchParameters = searchParameters;
try
{
page = targetingIdeaService.get(selector);
}
catch (Exception e)
{
return new string[] { e.ToString() };
}
// Display related keywords.
if (page.entries != null && page.entries.Length > 0)
{
foreach (TargetingIdea targetingIdea in page.entries)
{
Dictionary<AttributeType, Google.Api.Ads.AdWords.
v201802.Attribute> ideas =
targetingIdea.data.ToDict();
var keyword = (ideas[AttributeType.KEYWORD_TEXT] as
StringAttribute).value;
var averageMonthlySearches =
(ideas[AttributeType.SEARCH_VOLUME] as
LongAttribute).value;
var averageCpc = (ideas[AttributeType.AVERAGE_CPC]
as MoneyAttribute).value;
var competition = (ideas[AttributeType.COMPETITION]
as DoubleAttribute).value;
var monthlySearchVolume = (ideas[AttributeType.
TARGETED_MONTHLY_SEARCHES] as MonthlySearchVolumeAttribute).value;
var ideaType = (ideas[AttributeType.IDEA_TYPE] as
IdeaTypeAttribute).value;
var res1 = "{" +
"keyword: " + keyword +
", volume: " + averageMonthlySearches +
", averageCPC: " + averageCpc?.microAmount +
", competition: " + competition +
//", monthlySearches: " + monthlySearchVolume +
//", ideaType: " + ideaType +
"}";
return new string[] { res1 };
}
}
return new string[] { "test" };
}
}
Again: It works on localhost. I believe there is just some configuration
I'm missing.
