Did anyone have any success creating an app in C# and creating new listings using Etsy API. I have developed an app that works great for retrieving data (HTTP GET), with or without permissions. The only part that I cannot figure out is how to write a valid code for HTTP POST.
Here is a fully working HTTP GET example for retrieving all inactive listings:
public EtsyListings GetAllStoreListingsInactive(string storeProviderStoreId, string consumerKey, string consumerSecret, string oAuthToken, string oAuthTokenSecret)
{
string url = "shops/" + storeProviderStoreId + "/listings/inactive";
var request = GenerateSecureRequest(url, RequestType.GET, consumerKey, consumerSecret, oAuthToken, oAuthTokenSecret);
var response = _restClient.Execute<EtsyListings>(request);
if (response.ResponseStatus != ResponseStatus.Completed)
throw new Exception("Retrieving AllStoreListingsInactive Failed");
return response.Data;
}
private RestRequest GenerateSecureRequest(string url, RequestType requestType, string consumerKey, string consumerSecret, string oAuthToken, string oAuthTokenSecret)
{
OAuthBase oAuth = new OAuthBase();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string relativeUri = url;
string sig = oAuth.GenerateSignature(new Uri(BASE_URL.ToString() + relativeUri), consumerKey, consumerSecret, oAuthToken, oAuthTokenSecret, requestType.ToString(), timeStamp, nonce, out normalizedUrl, out normalizedRequestParameters);
var request = new RestRequest(relativeUri);
request.Resource = string.Format(relativeUri);
request.Method = Method.GET;
request.AddParameter("oauth_consumer_key", consumerKey);
request.AddParameter("oauth_token", oAuthToken);
request.AddParameter("oauth_nonce", nonce);
request.AddParameter("oauth_timestamp", timeStamp);
request.AddParameter("oauth_signature_method", "HMAC-SHA1");
request.AddParameter("oauth_version", "1.0");
request.AddParameter("oauth_signature", sig);
return request;
}
And here is the code I have written so far for creating a new listing, it is not working:
public EtsyListings CreateListing(string storeProviderStoreId, string consumerKey, string consumerSecret, string oAuthToken, string oAuthTokenSecret)
{
string url = "listings";
var request = GenerateSecureRequestTestingCreatingListing(url, RequestType.POST, consumerKey, consumerSecret, oAuthToken, oAuthTokenSecret);
var response = _restClient.Execute<EtsyListings>(request);
if (response.ResponseStatus != ResponseStatus.Completed)
throw new Exception("Retrieving Creating Listing Failed");
return response.Data;
}
private RestRequest GenerateSecureRequestTestingCreatingListing(string url, RequestType requestType, string consumerKey, string consumerSecret, string oAuthToken, string oAuthTokenSecret)
{
OAuthBase oAuth = new OAuthBase();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string relativeUri = url;
string sig = oAuth.GenerateSignature(new Uri(BASE_URL.ToString() + relativeUri), consumerKey, consumerSecret, oAuthToken, oAuthTokenSecret, requestType.ToString(), timeStamp, nonce, out normalizedUrl, out normalizedRequestParameters);
var request = new RestRequest(relativeUri);
request.Resource = string.Format(relativeUri);
request.Method = Method.POST;
request.AddParameter("oauth_consumer_key", consumerKey);
request.AddParameter("oauth_token", oAuthToken);
request.AddParameter("oauth_nonce", nonce);
request.AddParameter("oauth_timestamp", timeStamp);
request.AddParameter("oauth_signature_method", "HMAC-SHA1");
request.AddParameter("oauth_version", "1.0");
request.AddParameter("oauth_signature", sig);
request.AddParameter("title", "Test Title");
request.AddParameter("description", "Test Description");
request.AddParameter("quantity", "1");
request.AddParameter("price", "1");
request.AddParameter("is_supply", "false");
request.AddParameter("state", "draft");
request.AddParameter("when_made", "2010_2017");
request.AddParameter("who_made", "i_did");
request.AddParameter("shipping_template_id", "43862539760");
var response = _restClient.Execute(request);
return request;
}
Does anyone see anything obvious wrong with the CreatingListing code above?
The error code on response object I receive is 'StatusCode' of 'Forbidden', and 'Content' of 'oauth_problem=signature_invalid...'
I have verified I have full permissions, and the signature was not a problem with HTTP GET example I have provided above.
Additional info: Posting without 'quantity' parameter, I receive a 'BadRequest' error stating that 'Expected param 'quantity'.'
And reworking the code, so I will pass the object in the body:
private RestRequest GenerateSecureRequestTestingCreatingListing(string url, RequestType requestType, string consumerKey, string consumerSecret, string oAuthToken, string oAuthTokenSecret)
{
OAuthBase oAuth = new OAuthBase();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string relativeUri = url;
string sig = oAuth.GenerateSignature(new Uri(BASE_URL.ToString() + relativeUri), consumerKey, consumerSecret, oAuthToken, oAuthTokenSecret, requestType.ToString(), timeStamp, nonce, out normalizedUrl, out normalizedRequestParameters);
var request = new RestRequest(relativeUri);
request.Resource = string.Format(relativeUri);
request.Method = Method.POST;
request.AddParameter("oauth_consumer_key", consumerKey);
request.AddParameter("oauth_token", oAuthToken);
request.AddParameter("oauth_nonce", nonce);
request.AddParameter("oauth_timestamp", timeStamp);
request.AddParameter("oauth_signature_method", "HMAC-SHA1");
request.AddParameter("oauth_version", "1.0");
request.AddParameter("oauth_signature", sig);
request.AddParameter("quantity", "1");
request.RequestFormat = DataFormat.Json;
var dataObj = new
{
title = "This is a test1",
description = "Test Description1",
quantity = "1",
price = "1",
is_supply = "false",
state = "draft",
when_made = "2010_2017",
who_made = "i_did",
shipping_template_id = "43862539760"
};
string dataObjJson = JsonConvert.SerializeObject(dataObj, Formatting.Indented);
request.AddBody(dataObjJson);
//request.AddParameter("title", "Test Title");
//request.AddParameter("description", "Test Description");
//request.AddParameter("quantity", "1");
//request.AddParameter("price", "1");
//request.AddParameter("is_supply", "false");
//request.AddParameter("state", "draft");
//request.AddParameter("when_made", "2010_2017");
//request.AddParameter("who_made", "i_did");
//request.AddParameter("shipping_template_id", "43862539760");
var response = _restClient.Execute(request);
return request;
}
is resulting with the same Forbidden error
