## Initialize the SDK

Before using the SDK, you need to initialize the SDK with your API key. Please find your account API key in[ social.plus Cloud Console.](https://portal.amity.co/login)

After logging in Console:

1. Click **Settings** to expand the menu.
2. Select **Security**.
3. On the **Security** page, you can find the API key in the **Keys** section.

You can specify endpoints manually via optional parameters. API endpoints for each data center are different so you need to adjust the endpoint accordingly.

We currently support multi-data center capabilities for the following regions:

|     Region    |         Endpoint         |   Endpoint URL  |
| :-----------: | :----------------------: | :-------------: |
|     Europe    | AmityRegionalEndpoint.EU | api.eu.amity.co |
|   Singapore   | AmityRegionalEndpoint.SG | api.sg.amity.co |
| United States | AmityRegionalEndpoint.US | api.us.amity.co |

## Authentication

You must first register the current device with a `userId`. A device registered with a `userId` will be permanently tied to that `userId` until you deliberately unregister the device, or until the device has been inactive for more than 90 days. A device registered with a specific `userId` will receive all messages belonging to that user.
