Environment variables

About environment variables

Create sets of environment variables for your notebooks. Such variables can store passwords, API tokens, and other kinds of sensitive data for your notebooks to integrate with other services.

You can set up an environment variable for just one specific notebook or create one in a specific workspace and add it to any associated notebook.

Collaboration and permissions

This is how collaborators can manage environment variables:

Environment variable owners (creators) can manage them on the workspace and notebook level
Workspace collaborators with editor rights can attach already existing environment variables to, and detach them from, notebooks
Workspace collaborators with viewer right can view environment variables

Migrate secrets to environment variables

Environment variables are the new alternative to Secrets (soon deprecated). To preserve your secrets, migrate them to environment variables.

Click the avatar in the upper-right corner of the screen.
Select Account settings from the menu.
Switch to the Secrets tab.
Click the ellipsis for the secret you want to migrate.
Select Migrate secret to environment variable.

Example: Using an envrironment variable to pass a GitHub token

In the example below, information about the notebook owner's GitHub account is requested using an API token.

r = requests.get('https://api.github.com/user',
                auth=('user_name', os.environ["github_token"]))

The token is passed in an environment variable with the github_token key. Users with viewer rights can use the code below to view the secured value :

print(os.environ["github_token"])
