+
+All [service token](/docs/dbt-cloud-apis/service-tokens) traffic is subject to IP restrictions.
+
+When using a service token, the following 403 response error indicates the IP is not on the allowlist. To resolve this, you should add your third-party integration CIDRs (network addresses) to your allowlist.
+
+The following is an example of the 403 response error:
+
+```json
+        {
+            "status": {
+                "code": 403,
+                "is_success": False,
+                "user_message": ("Forbidden: Access denied"),
+                "developer_message": None,
+            },
+            "data": {
+                "account_id": <account_id>,
+                "user_id": <user_id>,
+                "is_service_token": <boolean describing if it's a service token>,
+                "account_access_denied": True,
+            },
+        }
+```
