+# How to Quickly Fix the 401 Error code?
+![401 Unauthorized Overview](./../../../asset/image/faq/auth-401-illustration.svg)
+
+After submitting an API call to Midtrans, it is possible to receive HTTP 401 Unauthorized error code response. This article discusses ways to troubleshoot a 401 (unauthorized) error code.
+
+## What is the 401 Error Code?
+The 401 (Unauthorized) error code indicates that the merchant server’s request was not verified. When accessing the Midtrans API, 
+your backend sends a request, which in this case was not verified. You will receive a simple message telling you that the 
+request is unauthorized, like the sample bellow.
+
+<!-- tabs:start -->
+#### **Response 401 Snap**
+```json
+{
+   "error_messages": [
+      "Access denied due to unauthorized transaction, please check client or server key",
+      "Visit https://snap-docs.midtrans.com/#request-headers for more details"
+   ]
+}
+```
+#### **Response 401 Core API**
+
+```json
+{
+   "status_code": "401",
+   "status_message": "Transaction cannot be authorized with the current client/server key.",
+   "id": "2e3d5c81-f80c-4aed-a40c-1298b4abfd93"
+}
+```
+<!-- tabs:end -->
+
+This means that an incorrect Server-Key/Client-Key are being used or server-key and client-key being used in the 
+incorrect environment. In order to verify the request, you need to use it with valid server-key and client-key.
+
+## How to Fix the 401 Error Code?
+
+The 401 Unauthorized error can be fixed by using any of the following ways:
+
+1. Check Server-Key and Client-Key: 
+   - Ensure that the **server-key and client-key are being passed correctly**. Please copy directly the value of server-key and client-key [from Midtrans Dashboard.](/en/midtrans-account/overview.md#retrieving-api-access-keys) 
+   - Ensure there are **no spaces** at the start or end of your server-key and client-key. 
+   - Check that your Apps/Backend **authenticating for the correct environment**. The credentials for Sandbox and Production are unique.
+
+2. Check The Endpoint API URL and Correct Environment:
+   - Sandbox and production are separate environments. **Make sure that you are not mistakenly executing your request in the incorrect environment.**
+   - **Use the correct URL for your environment**, See Sandbox base URLs and Production base URLs for more information.
+
+<!-- tabs:start -->
+#### **Base URLs**
