+## 10 Test
+The first version of the new test environment is ready for the Subscriptions facade. All features except Refund is available.
+
+### 10.1. Test credentials
+**Test merchant**: Find a guide to create test merchant [here](https://developer.vippsmobilepay.com/docs/developer-resources/portal/#how-to-create-a-test-sales-unit). The test credentials consist of a client id, client secret and subscriptions key. 
+
+**Test user**: Find a guide to create test users [here](https://developer.vippsmobilepay.com/docs/test-environment/#test-users) 
+
+*For partners*: Please contact [email protected] to request a DK or FI test merchant and user.
+
+Please note: If you want to reuse your Subscriptions test data you will need to recreate your test data. Please note that all test data, including payments, refunds, and so on, created on the old platform will not be migrated from the sandbox to the merchant test environment.
+
+### 10.2. Authentication 
+
+You will  have to integrate with the new and simplified Access Token API designed for the merchant test environment. The old MobilePay OpenId consent flow for the sandbox will cease to function. [Access token API guide](https://developer.vippsmobilepay.com/docs/APIs/access-token-api/).

+### 10.3 Headers and endpoints
