Asc Subscription Localization

rudrankriyam/app-store-connect-cli-skills

If you've ever had to click through 38 different language settings in App Store Connect just to set the same subscription name everywhere, this will save you an hour of your life. It wraps the asc CLI to bulk-create localizations for subscriptions, subscription groups, and in-app purchases across all supported App Store locales. You still need to have your subscription groups and products already set up, and you'll need asc auth configured, but once that's done you can push a display name to every locale with a series of commands instead of the web UI nightmare. The skill provides the full locale list and handles the tedious check-then-create workflow to avoid duplicate errors.

asc subscription localization

Use this skill to bulk-create or bulk-update display names and, where supported, descriptions for subscriptions, subscription groups, and in-app purchases across all App Store Connect locales.

Preconditions

Auth configured (asc auth login or ASC_* env vars).
Know your app ID (ASC_APP_ID or --app).
Subscription groups and subscriptions already exist.

Choose the API scope first

API 4.4.1 adds discrete versions for IAPs, subscriptions, and subscription groups. A version ID is different from its product, subscription, or group ID.

Use asc ... versions localizations ... for all new localization work.
Do not use the product- or group-scoped v1 localization commands. API 4.4.1 deprecates those resources, and the CLI now emits migration warnings for their compatibility commands.
Never pass a product, subscription, or group ID to a version-scoped command.

Resolve or create versions before localizing them:
