List environments

Retrieve the environments within an app.

Use this to enumerate every environment in an app. Identify the app by its project slug and app slug. Results are ordered by environment id. An app has only a handful of environments, so all of them are returned in a single response.

Required Permissions

Your root key must have the following permission:

environment.*.read_environment (to read environments in any app)

Authorization

Authorizationstringheaderrequired#

Unkey uses bearer tokens for authentication. Public integrations use root keys, while the dashboard proxy uses short-lived JWTs.
To authenticate, include the token in the Authorization header of each request:

Authorization: Bearer unkey_123

Root keys have specific permissions attached to them, controlling what operations they can perform. Legacy permissions use tuple strings like api.*.create_key; resource permissions use Unkey Resource Names plus actions, like unkey:v1:ws_123:keyspaces/*#create_key.
Security best practices:

Keep root keys secure and never expose them in client-side code
Use different root keys for different environments
Rotate keys periodically, especially after team member departures
Create keys with minimal necessary permissions following least privilege principle
Monitor key usage with audit logs.

Body
