+
+API key permissions let admins limit what a developer API key can do. Instead of one key with full access to every endpoint, you can issue keys that are scoped to specific operations, for example a key that can only translate text or a key that can only read glossaries.
+
+Permissions are implemented as scopes. Each scope groups a set of related operations into a single capability you can grant to a key. This page uses "permissions" for the user-facing feature and "scopes" for the technical mechanism.
+
+Permissions are currently supported only for developer API keys. An account can hold any mix of scoped and unrestricted developer keys.
+
+### How scopes work
+
+Developer keys can be turned into scoped keys by assigning them one or more scopes. Once a key is scoped:
+
+- It can call only the endpoints fully covered by its scopes.
+- Every other endpoint returns `403 Forbidden` including any endpoint that has no scope requirement of its own.
+- Some endpoints require more than one scope. A key must hold all of them; if any is missing, the request is denied and the response lists the missing scopes.
+
+<Warning>
+    Scopes are enforced only on scoped keys. Unrestricted keys retain full access to every endpoint. Existing keys remain unrestricted by default, but admins can assign them scopes at any time.
+</Warning>
+

+### Create a scoped key
+
+Open the [Keys](https://www.deepl.com/your-account/keys) page in your account. Click "Create key" and optionally name the key.
+
+Select **Custom permissions**, then choose one or more scopes from the list.
+
+Click "Create key" to confirm. The key is created with the chosen scopes and shown once in a popup so you can copy it.
+
+<Frame caption="Creating a scoped API key">

+</Frame>
+
+### Edit scopes on an existing key
+
+You can change scopes on any existing developer API key, including keys that were originally unrestricted.
+
+In the API keys table, open the key's menu and select "Edit permissions". Choose **All access** to make the key unrestricted, or **Custom permissions** to select specific scopes. Click "Save" to apply.

+
+### Identify scoped and unrestricted keys
+
+The API keys table includes a column showing each key's permissions. Hover over the badge to view the assigned scopes.

+
+### Error responses
+
+When a scoped key calls an endpoint outside its scopes, the API returns a `403 Forbidden` response. To resolve it, call an endpoint covered by the key's scopes, or add the missing scope to the key.
