 ## Create NinjaOne API Credentials
 
-1. Log in to your NinjaOne portal
-2. Navigate to **Administration** > **API** > **Add Application**
-3. Configure the application:
-    - **Application Name**: Enter a descriptive name (e.g., "SquaredUp Integration")
-    - **Allowed Grant Types**: Ensure "Client Credentials" is enabled
-    - **Scopes**: Select the following scopes:
-        - `monitoring` - Required for device monitoring data
-        - `management` - Required for management operations
-        - `control` - Required for control operations
-        - `offline_access` - Required for refresh tokens

+    - **Allowed grant types**: `Refresh token` is **not** required by the plugin and can be left unticked.
+5. Save the application. NinjaOne will then show the **Client ID** and **Client Secret** — copy both, as you'll need them when configuring the plugin in SquaredUp. (The Client Secret is only shown once on creation; if you lose it, use **Generate new secret** to issue a new one.)

-**Authentication Failed**: Ensure your Client ID and Client Secret are correct and that "Client Credentials" is enabled as an allowed grant type in your NinjaOne API application.
+**Authentication Failed**: Verify your Client ID and Client Secret are correct. Also check that your NinjaOne client app was created with the **API Services** application platform — this is what makes Client Credentials the active grant type. There is no separate "Client Credentials" checkbox in the client app screen; if you picked a different platform (e.g. Web app), the OAuth token request will fail.
 
 **No Data Returned**: Verify that the selected API Region matches your NinjaOne instance region.
