YouTube Music — Direct

1. Capture your refresh token

1. Install Proxyman on your Mac or iPhone/iPad (or Charles Proxy works too).
2. In Proxyman: Certificate → Install Certificate on iOS. Trust it on your iPhone in Settings → General → About → Certificate Trust Settings.
3. Enable SSL Proxying for oauthaccountmanager.googleapis.com: in Proxyman, tap the More tab (bottom right) → SSL Proxying List → Add Include Entry, then enter oauthaccountmanager.googleapis.com and save.
4. Open the YouTube Music app on your iPhone (force-quit and reopen if it was already running).
5. In Proxyman, find any POST /v1/issuetoken request on oauthaccountmanager.googleapis.com and tap it → Raw tab.
6. Look for the Authorization: Bearer 1//0... line in the request headers. The long string starting with 1//0 is your refresh token — copy everything after Bearer (no spaces, no line breaks) and paste it below.

2. Generate your addon URL

FAQ

Can I revoke it? Yes. Revoke device access at myaccount.google.com/device-activity — this invalidates the refresh token immediately and you can re-run setup with a fresh one.

How long does it last? Google refresh tokens typically work for 12+ months unless you change your password or revoke device access.
