# Call Web Service

Use the Call Web Service component to call REST web services. Assign the result to a control on the page to show what the service returned.

**When to use a Web Service *****connector***** instead?**

Using a [connector](https://docs.stadium.software/connectors) is the preferred way of working with web services. However, the Call Web Service action is better suited to web service calls when authentication is dynamic, i.e. the credentials, like API keys, change for every call you make.

**More on REST API's**

Popular service providers, including Yahoo, Google and Facebook, have implemented the REST model of API's to expose their services. Read more about REST [here](http://en.wikipedia.org/wiki/Representational_state_transfer).
