SSIS Web Service Task

The SSIS Web Service Task is used to execute the web service methods. For instance, if you want to store the weather report as an SQL extra column, then consume the Web service provided by the Yahoo or MSN weather, and store the output in a variable so that you can pass the variable to Data Flow Task.

In this article, we show you how to consume the web service methods using the SSIS Web Service Task with example. Before we start configuring the Web Serve Task in SSIS, let us see the list of the available method in our service.

NOTE: The SSIS Web Service Task uses the HTTP Connection Manager to connect with the Web service and to send or receive Files.

The below screenshot shows you the Methods available in this SSIS web service Task. Our task is to consume the GetCityForecastByZip method available in this web service. Please visit https://wsf.cdyne.com/WeatherWS/Weather.asmx website to use the same service.

Once you click on the <New Connection..> option, HTTP Connection Manager Editor will be opened to configure it.

  • Server URL: Please specify the URL of the web service. If you are planning to download the WSDL file using the Download WSDL button, type the URL of the WSDL file; otherwise, choose the service URL.

  • Chunk size(in KB): Please specify the chunk size for the writing data.
  • Test Connection: This button will help us to check whether we successfully established the connection to web service or not. Based on the result, we can alter the connection settings.
SSIS Web Service Task 5

In this example, we are selecting the Web service from a free source. So, we don’t have to configure the credentials and proxy settings. From the below screenshot, you can observe that we are providing the Service URL: https://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL because we want to download the WSDL file.

SSIS Web Service Task 6

Click OK to close the HTTP Connection Manager.

WSDL File: If you already downloaded the WSDL file, then we have to select the .wsdl file from your local file system. Otherwise, create an empty file with WSDL extension in your local hard drive and then click on the …. button beside the WSDLFile option.

Once you click on the …. option, a new window will open. Using this, we can create a New WSDL file in your local file system or select the Existing File from the file system. From the below screenshot you can observe that we are choosing the existing file called web.wsdl

SSIS Web Service Task 7

OverwriteWSDLFile: This SSIS Web Service Task property has two options: True and False. If we set this property to true, the Web Service Task will overwrite the existing WSDL files in the local file system.

SSIS Web Service Task 8

Next, click on the Download WSDL button to download the WSDL file, and if it exists, it will overwrite the existing file.

SSIS Web Service Task 12

Since this method accepts the Zip code as a parameter, we are providing the Zip code of California. Here we have an option to choose the variable also.

SSIS Web Service Task 13

Next, click on the SSIS Web Service Task Output tab to configure the Output data.

If we set the OutputType to File connection, we have to configure the Output Connection as File Connection Manager. It means the output XML data stored in a local file system.

SSIS Web Service Task 14

If we set the OutputType to Variable, then we have to configure the Output Connection as Variable. It means the output XML data stored in a variable. This option is handy because we can use this XML data in other tasks or transformations.

Once you click on the <New Connection..> option, a new window called File Connection Manager Editor opened. Using this, we have to configure the Output Connection.

SSIS Web Service Task 16
