**Fill in the information to create the application.** > The application details you create will be displayed on the frontend page.

**Note: When registering as a merchant, please add the UID of your developer to the whitelist. This allows you to test authorized login in the production environment:** > Whitelist UID format (comma-separated English characters, no spaces): UID1,UID2,UID3,… After adding to the whitelist, you can use a whitelisted UID account to log in to the Gate App. You will then see your merchant mini-program App in the Pay App application list and can proceed to test the authorization process. **4. Authorization login integration:** **Please refer to the API documentation for integration and testing of authorized login (using the authorization key and corresponding client ID):** https://www.gate.com/docs/miniapp/manual/en/ **5.

After completing payment feature integration, delete the application corresponding to the test payment client_id2. Deploy the code for client_id1, which has successfully passed all process tests, on your own server (replace client_id2 with client_id1). Apply for your App to go live in the Merchant Dashboard. All subsequent authorization and payment operations will use client_id1.**
