On this page, you can add/edit/remove environment variables that are used by your application.
### Add Environment Variable
1. Click **Add Variable**
2. Enter variable name (1), variable value (2) and click **Save** (3).
After the environment variable is added, redeployment will be required for changes to be applied.
### Edit Environment Variable
Click on "**Pencil" icon** to open the environment variable edit modal.
When finished editing the value, click **Save**.
After the environment variable is added, redeployment will be required for changes to be applied.
### Remove Environment Variable
Click on **Trash Icon**(1) near the variable you want to remove then click on **Delete** button (2).
In the opened modal, confirm that you want to delete a variable by clicking the **Yes, Delete** button.
If the variable is new and has not been deployed yet, it will be removed **immediately**.
If the variable was already deployed, you will see in **See Changes** that it will be removed **after** deployment.
## Raw Editor
Open Raw Editor modal
Raw Editor ENV view
Inside the Raw Editor modal, you can copy all environment variables, add/edit/delete them in bulk. And view them in JSON.
## Hyva Credentials
The Variables Management page also includes **Hyva Credentials** modal.
Here you can enter the **Hyva License Key** and the **Hyva Composer Repository** directly. Portal will also perform a check to see if the provided license key has access to the Hyva theme.
## Packagist
To install packages from Packagist, you need to provide **Composer Credentials** environment variable or have `auth.json` file in the repository. It is generally **recommended against** committing `auth.json` into the source code.
Instead, use `COMPOSER_AUTH` environment variable.
