c# - (13) The merchant login ID or password is invalid or the account is inactive

Question

I want to implement Authorize .net payment gateway in my website using asp.net. I am a beginner in this. Can someone give me a sample code from where I can be redirected to the Authorize.net page to complete payment process. I have created a sandbox account. Redirection URL - https://test.authorize.net/gateway/transact.dll but I get an error

(13) The merchant login ID or password is invalid or the account is inactive.

My account is active and in test mode.

My Code:

protected void Button_pay_Click(object sender, EventArgs e)
    {
        string value = TextBox_amt.Text;
        decimal d = decimal.Parse(value);
        Run("abc", "abcq234", d);
     }
 public static ANetApiResponse Run(String ApiLoginID, String ApiTransactionKey, decimal amount)
    {
        Console.WriteLine("Create an Accept Payment Transaction Sample");

        ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = AuthorizeNet.Environment.SANDBOX;

        // define the merchant information (authentication / transaction id)
        ApiOperationBase<ANetApiRequest, ANetApiResponse>.MerchantAuthentication = new merchantAuthenticationType()
        {
            name = ApiLoginID,
            ItemElementName = ItemChoiceType.transactionKey,
            Item = ApiTransactionKey,
        };

        var opaqueData = new opaqueDataType
        {
            dataDescriptor = "COMMON.ACCEPT.INAPP.PAYMENT",
            dataValue = "119eyJjb2RlIjoiNTBfMl8wNjAwMDUyN0JEODE4RjQxOUEyRjhGQkIxMkY0MzdGQjAxQUIwRTY2NjhFNEFCN0VENzE4NTUwMjlGRUU0M0JFMENERUIwQzM2M0ExOUEwMDAzNzlGRDNFMjBCODJEMDFCQjkyNEJDIiwidG9rZW4iOiI5NDkwMjMyMTAyOTQwOTk5NDA0NjAzIiwidiI6IjEuMSJ9"

        };

        var billingAddress = new customerAddressType
        {
            firstName = "John",
            lastName = "Doe",
            address = "123 My St",
            city = "OurTown",
            zip = "98004"
        };

        //standard api call to retrieve response
        var paymentType = new paymentType { Item = opaqueData };

        // Add line Items
        var lineItems = new lineItemType[2];

        var transactionRequest = new transactionRequestType
        {
            transactionType = transactionTypeEnum.authCaptureTransaction.ToString(),    // charge the card

            amount = amount,
            payment = paymentType,
            billTo = billingAddress,
            lineItems = lineItems
        };

        var request = new createTransactionRequest { transactionRequest = transactionRequest };
