## CORS mechanism

{% hint style="warning" %}
**Important.** Without doing this, requests from the browser will be blocked.
{% endhint %}

In case you are making requests to CodeMash from a browser, you will need to setup allowed origins in your project settings.

### Setting up allowed origins

* Go to your project settings
* Find a setting called **Allowed origins**.
* Add all allowed domains separated by comma (,).
