# Testing tool ## REST clients Any REST client may be used to test and consume our SCIM REST web service. ### RESTer In this case, we will show the usage with RESTer, a browser extension available for Chrome and Firefox.

This extension may be added from these links: [Chrome](https://chrome.google.com/webstore/detail/rester/eejfoncpjfgmeleakejdcanedmefagga), [Firefox](https://addons.mozilla.org/es/firefox/addon/rester/)

Once it's added to the browser, this tool is accessible from its toolbar icon: [![RestTer_1.png](https://bookstack.soffid.com/uploads/images/gallery/2021-05/scaled-1680-/restter-1.png)](https://bookstack.soffid.com/uploads/images/gallery/2021-05/restter-1.png) This is the RESTer application window: [![RESTer_2.png](https://bookstack.soffid.com/uploads/images/gallery/2021-05/scaled-1680-/rester-2.png)](https://bookstack.soffid.com/uploads/images/gallery/2021-05/rester-2.png)

Remember to use the HTTP headers specified in SCIM in [SCIM in Soffid-HTTPrequest](https://bookstack.soffid.com/link/114#bkmrk-http-request)

Remember to use a user with authorization. See 8. How to use SCIM in [How to use SCIM in Soffid-Confirmauthorization](https://bookstack.soffid.com/link/120#bkmrk-confirm-authorizatio)

### Postman Postman is another REST client, you can use it as an extension of the browser, but we recommend the operating system application.
