# App Keys

App keys are used to authorize third-party applications to interact with KEYZY.

## Adding a New App Key

1. To go to the App Keys page, click the **App Keys** icon in the menu bar.
2. To create a new App Key, click the **“Add new App Key”** button. To edit an existing App Key, click on its ID.
3. This will open a pop-up box where you can modify:
   - The write permission setting for the respective app key
   - Whether the app key is active or not

## Applications with Write Access

Typical examples of applications with write access are **web apps**. They request new licenses and need write authorization. Besides confirming if the serial number is correct, they can modify information, for example, the time of purchase.

## Applications without Write Access

Typical examples of applications without write access are **desktop apps**. They can only query the server to confirm that the serial number is correct.

## Best Practices

We suggest you create a **read permission** App Key for each application and a **write permission** App Key for each e-commerce store you have.

The search bar allows you to search app keys by any term in the app key columns, by API key, or by app ID.
