How to Use Argument Ports to Generate URL Parameters

You can use argument ports to generate parameters in the URL to filter the data that you request from the web service. For example, if you use the Get method, you cannot configure a method input definition or an input mapping, but you still want to use a filter in the Get request. You can use argument ports to create a filter in the request message. Build a URL such as

https://sample.com?arg1=val1&arg2=val2

by using argument ports to generate the URL parameters.

To configure an argument port after you create the REST Web Service Consumer transformation, complete the following steps:

Select the REST Web Service Consumer transformation.

Navigate to the

Properties

view and select the

Advanced

tab.

To configure the base URL, complete one of the following steps:

To configure the

URL

property, enter the base URL.

To configure the

Connection

property, select the HTTP connection.

Navigate to the

Ports

tab.

Highlight the

RequestInput

group and select

New

. Select

Argument Ports

from the drop-down menu.

This image shows the Ports tab of the REST Web Service Consumer transformation. The RequestInput group is highlighted. New is selected and the drop-down menu is shown. In the drop-down menu, Argument Ports is selected.

Enter values for

Argument Name

and

Port Name

If the port name contains characters that the Data Integration Service cannot process, change the port name.

The following image shows the argument port nested under RequestInput:

This image shows the Ports tab of the REST Web Service Consumer transformation. The URL port appears under the group RequestInput.

Repeat steps 3 and 4 to add a second argument port.

The second argument port appears under the first argument port:

This image shows the Ports tab of the REST Web Service Consumer transformation. There are two argument ports nested under RequestInput. The first argument port has a value of arg1 and the second argument port has a value of arg2.

The argument port values are appended to the URL in the format

http://sample.com?arg1=val1&arg2=val2

. The port name is not used in the URL. The Data Integration Service uses the port name to identify the argument ports.

To use the argument ports

arg1

and

arg2

as parameters in the base URL, link ports from an upstream mapping object to the argument ports in the REST Web Service Consumer transformation.

The ports linked from an upstream object define

val1

and

val2

in the URL

https://sample.com?arg1=val1&arg2=val2
