## How to update the user avatar?&#x20;

1. Get an avatar link from the input
2. [Use the Update Avatar action](#update-avatar) to change it
3. Save the updated avatar in the user data global variable

## Updating username&#x20;

The **Update Username** action is used to update the username for the logged-in user. If a new username is provided, it updates the user's profile with the new name; otherwise, it removes the username field. It sends a `PATCH` request to update the user's personal details using the `x-account-userid` and `Authorization` headers, which contain the user's ID and access token.

Once the username is successfully updated, the **On Username Updated** condition is triggered. The new username can be retrieved by calling the **Get Username** expression from the plugin.

## Update avatar

The **Update Avatar** is used to update the avatar for the logged-in user. If a new avatar URL is provided, it updates the user's profile with the new avatar; otherwise, it removes the avatar field. It sends a `PATCH` request to update the user's personal details using the `x-account-userid` and `Authorization` headers, which contain the user's ID and access token.

Upon successful avatar update, the **On Avatar Updated** condition is triggered. The new avatar URL can be retrieved by calling the **Get Avatar** expression from the plugin.
