galaxy_store_upload_metadata

The Galaxy Store fastlane plugin action galaxy_store_upload_metadata reads app metadata from the local fastlane/metadata/galaxystore/ directory, uploads any image assets (icon and screenshots), and submits everything to Galaxy Store using the Content Publish API.

Action

galaxy_store_upload_metadata(
    content_id: "000007654321"
)

Parameter	Description	Required	Default
access_token	Galaxy Store Content Publish API access token	Yes*
service_account_id	Galaxy Store service account ID	Yes*
content_id	12-digit app content ID	Yes
default_language_code	Language code for the default listing	No	ENG
metadata_path	Path to the metadata folder	No	fastlane/metadata
upload_hero_image	Upload hero_image.<ext> if present. Only enable for Game-category apps — the API rejects hero images for other categories	No	false

*May also be set using environment variables or explicit parameters — see Authentication.

The action scans the galaxystore/ directory for:

icon.png (or other image extension) at the top level
hero_image.png at the top level (uploaded only when upload_hero_image: true)
youtube_url.txt at the top level
title.txt, short_description.txt, long_description.txt, new_feature.txt in each language directory
Images in each language's screenshots/ subdirectory

Only languages and fields that exist locally are included in the update payload.

NoteThe Content Publish API exposes additional listing fields (for example, support email, privacy policy URL, copyright holder, age limits, categories) that this action does not touch. You can manage them through Galaxy Store Seller Portal. The local directory format is additive-only: new top-level files or per-language files for these fields can be added in future releases without breaking existing setups.
