You can upload all of your game's assets and provide game information in the Instant Games section of the App Dashboard. Please note that all assets are mandatory. Your game will be rejected if all the assets are not provided. Additionally, the game may not display correctly without all of the assets, so we recommend uploading them all before testing your game.
We need the following information about your game:
Small App Icon (16 x 16) and App Icon (1024 x 1024) will appear in native dialogs on top of the game before and after each game session and in several other surfaces and entry points. It's important to have both game icons, otherwise the game will be shown with a default application icon.
Important note: Make sure to upload a square image without transparent background as App icon (1024 x 1024).
Similar to the assets above, the Cover Image (800 x 150) and the Banner (1200 x 627) are pieces of artwork that our platform needs to load in order to display our native dialogs, News Feed posts, and Messenger attachments correctly.
This image will be shown to players while they wait for the game to load. The image's resolution should be 750x1334.
You should provide a short - and ideally looped - video showcasing gameplay. We recommend 16:9 or 1:1 aspect ratios. Even if your game is in portrait mode, consider optimizing your video for these aspect ratios because News Feed stories are rendered in a landscape-oriented space. In those cases, consider cropping the gameplay video to a rectangular landscape portion of the screen or adding extra information to fill the sides of the video.
Remember, the video needs to showcase gameplay and should not look like an advertisement.
Find more information for Instant Games asset sizes under App Center documentation.
You can localize your game information and provide localized game's assets in the Localize tab under Instant Games section of the App Dashboard. This isn't mandatory but highly recommended to ensure the best experience for your users.
