1. REST Parameters
1.1. Watch the video tutorial
1.2. Resource Parameters
In this section we take a more detailed look at the different types of REST Parameters available to you in SoapUI.
There are five types of parameters available: QUERY, HEADER, TEMPLATE, MATRIX and PLAIN.
All parameters can be defined either at the RESOURCE level or at the METHOD level. Defining a parameter at the RESOURCE
level means that it is inherited by all method nodes under it, and by all requests under the METHOD nodes. Defining
it on the METHOD level only propagates the parameters to the requests; it does not affect the RESOURCE level.
Now, let’s have a look at different parameter types (except the PLAIN type which is ignored) to see how they can be used for
parameterizing your resources.
1.3. QUERY Parameters
QUERY parameters are the most common type of parameter, which is appended to the path of the URL when submitting a
request. You can see them added to the path after a ‘?’ in the path preview at the top of the REST Request
If you are simulating HTML Form submits, you might want to them to use the POST method instead. If we create a
corresponding REST Method using the POST (or PUT) verb you will get an option to post query-parameters in the body
As you can see selecting the option removes the parameter from the path, and if you submit and look in the Raw tab
you will get:
As you can see the parameters have been added to the body of the message instead, with the corresponding
Content-Length set accordingly.
HEADER parameters are instead added as HTTP Headers to the outgoing request. Let’s define one at the Method
Setting a value and submitting the request gives the following in the Raw request tab:
1.5. TEMPLATE Parameters
TEMPLATE parameters are a flexible way of parameterizing the actual path of the request. For instance, if you
are using the FreeGeoIP REST API, which expects
the IP address as part of the path, defining a TEMPLATE parameter for the address is quite handy:
Now we can just change this parameter to run queries using different IP addresses:
NOTE: TEMPLATE parameters really only make sense on the RESOURCE level. It is technically possible to have them on the METHOD level, but we don't recommend it. If you define a TEMPLATE parameter on the METHOD level, it will not be automatically appended to the resource path — you will have to manage it manually.
Finally, if we instead use the From view of the request (in soapUI Pro only), we can now see what the extra metadata
added for the parameter is used for (besides for creating nicer WADLs):
Here the format is rendered as a drop-down with the "csv", “xml” and “json” options available.
1.6. MATRIX Parameters
MATRIX parameters are another way of defining parameters to be added to the actual path of the resource, but before
the query string. They are not as common but never the less specified in the WADL spec and thus supported by soapUI.
Add a MATRIX parameter to the weather method (as we did for the HEADER parameter above):
As you can see, the parameter is added to the path before the query string. Submitting the request now gives a 404

This is trustily added to the response representations for the method as a Fault Representation:
