Set up AMS configuration - Game server integration - (Unreal Engine module)

Last updated on September 28, 2026

About​

AccelByte Multiplayer Servers (AMS) is a dynamic dedicated game server manager that enables you to serve dedicated game servers as close to your players as possible. You can learn more about what AMS has to offer in the AMS documentation.

To start using AMS, you need to create an AMS account and link your game namespace to it. You also need an IAM Client to manage your game server on AMS, such as upload your game server build and claim your dedicated servers from your fleet.

Create AMS IAM client​

To manage your dedicated servers on AMS, such as uploading new server build and claiming dedicated servers from your backend, you need an IAM client with enough permission to do those actions. In this tutorial section, you will learn how to create that IAM client.

  1. Log in to the Admin Portal and go to your game namespace dashboard.

  2. Go to Foundations > Identity & Access > IAM Clients and click Create New.

  3. In the What is this client for? window, select Custom and click Continue. The New IAM Client page appears.

  4. In the Client Type section, select Confidential.

  5. In the Basic Info and Client Settings sections, use the configuration below to create a new server IAM client.

    • Client Name: the name of the IAM client. Set it to ByteWars-AMS.
    • Secret: the secret or password for the IAM client. You can use your own secret or click Generate to generate a random one.
    • Redirect URI: the URI used to redirect once the IAM client authorization is successful. Select Localhost, which sets it to http://127.0.0.1.

  6. In the Permissions section, enable the permission below. This permission allow you to upload game server build to AMS and simulating AMS server locally.

    • AMS > Dedicated Server Toolkit: enable Read, Create, and Update permissions.

  7. Click Continue. The Save your client secret window appears. Click Copy secret and save the secret somewhere secure. Then, tick I have copied and stored this client secret securely and click Create to create your IAM client.

    warning

    The Secret will not be shown again after you create the IAM client. Be sure to copy and save it before you click Create.

Configure the AGS SDK​

Before using the AGS Game SDK, you will need to configure it to use the IAM client you just created.

  1. Open /Config/DefaultEngine.ini in a text editor.

  2. Find the [/Script/AccelByteUe4Sdk.AccelByteServerSettings] and [/Script/AccelByteUe4Sdk.AccelByteSettings] section inside DefaultEngine.ini and replace the values with a dummy value. This setup is used for AccelByte Gaming Services (AGS) integration, since you won't be using that in this module, set it to any value.

    [/Script/AccelByteUe4Sdk.AccelByteServerSettings]
    ClientId=DUMMYCREDS
    ClientSecret=DUMMYCREDS
    Namespace=DUMMYCREDS
    PublisherNamespace=DUMMYCREDS
    RedirectURI="http://127.0.0.1"
    BaseUrl=DUMMYCREDS

    [/Script/AccelByteUe4Sdk.AccelByteSettings]
    bServerUseAMS=true

  3. Save the DefaultEngine.ini file and rebuild your Byte Wars project.
