App Store Connect API signing key and JWT jwt discovered Get key ↗

In App Store Connect API docs, create an App Store Connect API key from your organization's App Store Connect account, download the private key once, then sign your own JWTs for API requests. Apple notes there are team and individual keys, and calls to the API use the signed JWT in the Authorization: Bearer header.
