# Registration

### App Registration and Key Issuance

To use Wepin's RESTful API, you must first register your app in the [Wepin Workspace](https://workspace.wepin.io/login). Navigate to the Wepin Workspace, register your app, and obtain the necessary keys. For detailed instructions, refer to the [**App Registration and Key Issuance** page](/en/wepin/workspace/app-registration-and-key-issuance.md).

Once the app registration is complete, you will receive the following information:

* **App ID**: App identifier number
* **App Key**: Connection key for Wepin's RESTful API

**Requesting API Access**

Next, go to the **Platform** tab under the Developer Tools menu and click the **Request RESTful API Access** button.

When you click the **Request Access** button, a "Request REST API Access" window will appear. Complete the short survey about your intended API use, select the platforms you want to use the API with (Web, Android, iO&#x53;**;** multiple selections are allowed), enter a name, and then click the **Submit Request** button.

After completing the RESTful API application, check your registered email for an application confirmation message from Wepin Workspace. Once you receive the confirmation email, your registration process is complete.
