Using Claude to Automate App Store Connect Metadata Updates for 33 Languages

An indie iOS developer shared on Reddit how they used Claude to automate App Store Connect (ASC) metadata updates across 33 languages. The manual process of switching locale by locale and pasting copy for each update was taking 1–2 hours. Claude helped generate a Python script that handles the entire pipeline with no manual coding.

What the Script Does

• Authenticates with the App Store Connect API using JWT signing (Issuer ID, Key ID, and .p8 file)
• Translates app name, subtitle, description, and keywords into 33 languages, including competitive keyword suggestions per locale
• Pushes localized “What’s New” copy to all locales in a single run
• Handles edge cases automatically: Apple’s 30-character subtitle limit and 409 conflict errors

Key Technical Details

All code was generated through chat with Claude — the developer didn’t write a single line themselves. Claude explained the relevant endpoints and JWT signing process. After generating the script, the developer only reviews the copy, approves it, and runs it. The script is saved in a reusable folder and has been used across three apps in one week.

Who It's For

Indie iOS developers who localize their apps and want to cut down repetitive App Store Connect data entry.
