# Activities Generated from Web Services

> **Studio** enables you to generate activities directly from web services by using the **New Service** wizard, as explained [here](https://docs.uipath.com/studio/docs/loading-web-services-in-libraries). After being generated and loaded into the project library, the activities can be easily browsed in the **Activities** panel.

**Studio** enables you to generate activities directly from web services by using the **New Service** wizard, as explained [here](https://docs.uipath.com/studio/docs/loading-web-services-in-libraries). After being generated and loaded into the project library, the activities can be easily browsed in the **Activities** panel.

These activities have a dual structure, one part being standardized, while the other depends on the actual web services you generate the activities from.

First, the class of the activity has the structure `UiPath.WebClient.[ServiceName].[RequestName]`, where `[ServiceName]` is the name of the web service, and `[RequestName]` is the name of the API call based on which the activity is generated.

The properties in the **Client** property section vary according to what kind of web service the activity was generated from. The two main properties they can have are **Request** and **Response**. The **Request** property can contain sub-properties as they are defined in the web service you are using.

:::note
Activities generated from **SOAP** and **Swagger** services cannot be localized in Studio.

A typical property structure looks like this:

## Client

* **Request** - The request that you want to send to the web service.
* **Response** - The response received from the web service.

## Client Certificate Authentication

* **ClientCertificate** - The full path to the client certificate file on your hard drive. This field supports only strings and String variable.
* **ClientCertificatePassword** - The password for the specified client certificate file. This field supports only strings and String variable.

## Common

* **DisplayName** - The display name of the activity.
* **TimeoutMS** - Specifies the amount of time (in milliseconds) to wait for the activity to run before an error is thrown. The default value is 30000 milliseconds (30 seconds).

## Misc

* **Headers** - Enables you to include custom headers in the HTTP request. Click the **Ellipsis** button to open the **Headers** window.
* **Private** - If selected, the values of variables and arguments are no longer logged at Verbose level.

## Simple Authentication

* **Username** - Indicates that the web service uses simple authentication and enables you to input your username. Adding a password is also required. This property supports strings and string variables.
* **Password** - Indicates that the web service uses simple authentication and enables you to input your password. Adding a username is also required. This property supports strings and string variables.

## Windows Authentication
