SDK for Unity (PC, web)

Error when calling authentication method

Issue description

The issue appears when you call user authentication method from the code, or when starting the application and trying to authenticate the user. When this occurs, the following error message is displayed:

Copy
Full screen
Small screen
    Request is missing required parameter, includes invalid parameter value, includes parameter more than once, or is malformed.
    

    The problem occurs in the following cases:

    • The user redirect URI is not specified in Publisher Account.
    • There are different user redirect URIs in Publisher Account and in the SDK settings.

    Issue status: Can’t be fixed on the SDK side.

    Fix

    To set up the new OAuth 2.0 client, follow the instructions.

    To specify or change the redirect URI for an already configured OAuth 2.0 client:

    1. Open your project in Publisher Account and go to the Login section.
    2. Click Configure in the pane of a Login project.
    3. Go to the Security block and select the OAuth 2.0 section.
    4. Click on the pencil icon in the line of the required OAuth 2.0 client.
    5. Specify OAuth 2.0 redirect URIs (a path in the application the user is redirected to after successful authentication, email confirmation, or password reset). You can specify multiple valid URIs.
    Notice

    For desktop or web applications, the URI must start with https://. By default, the SDK uses https://login.xsolla.com/api/blank. Specify this URI or use your own.

    The URI must match the value specified in the SDK settings (Window > Xsolla > Edit Settings > Inspector) in the Callback URL field.

    1. Click Save changes.
