401 Unauthorized error with correct credentials.

まず、getMyMerchantDetails() のプロパティを、動作する例である getMerchantDetails() と比較し、加盟店 ID、キー ID、シークレットキー、認証タイプ、実行環境に注目します。https://apitest.cybersource.com/pts/v2/payments に対するリクエストを再現し、修正後の設定が 401 Unauthorized ではなく、期待される 201 レスポンスを返すことを確認します。

I followed the documentation and set up my API credentials as below:

public static Properties getMyMerchantDetails() {
		Properties props = new Properties();

		// HTTP_Signature = http_signature and JWT = jwt
		props.setProperty("authenticationType", "http_signature");
		props.setProperty("merchantID", "my_web_au");
		props.setProperty("runEnvironment", "apitest.cybersource.com");
		
		props.setProperty("merchantKeyId", "my_merchant_id");
		props.setProperty("merchantsecretKey", "my_sercret_key");
		props.setProperty("useMetaKey", "false");
		props.setProperty("enableClientCert", "false");

		return props;

	}

it gives me 401 unauthorized error:
Response{protocol=http/1.1, code=401, message=Unauthorized, url=https://apitest.cybersource.com/pts/v2/payments}

public static Properties getMerchantDetails() {
		Properties props = new Properties();

		// HTTP_Signature = http_signature and JWT = jwt
		props.setProperty("authenticationType", "http_signature");
		props.setProperty("merchantID", "testrest");
		props.setProperty("runEnvironment", "apitest.cybersource.com");
		props.setProperty("requestJsonPath", "src/main/resources/request.json");

		props.setProperty("useMetaKey", "false");

		// HTTP Parameters
		props.setProperty("merchantKeyId", "ggggggggggg");
		props.setProperty("merchantsecretKey", "gggggggggg");
		props.setProperty("enableClientCert", "false");
	
		return props;

	}

The above gives which is me 201 proper response.

I am sure my credentials are correctly created. Is there anything else I should add or modify to get past authorization?
