Transfer checklist

Before you start

API access is on for your account and you have a Send releases key.
An export of your catalog from your previous distributor, with every release’s UPC and every track’s ISRC.
The original release date of each release.
Each artist’s Spotify and Apple Music profile IDs, and legal names.
Songwriter names (legal first and last), shares, and IPI numbers where you have them.
Performer and production credits for every track.
The original masters (WAV or FLAC) and artwork (square, at least 1400×1400), on a host we accept.

Send one release first. Send it, wait for its files, and validate it. Fix anything your export gets wrong before sending the rest.
Send the rest under one transfer ID. Keep each release’s ID the same as in your system, so you can re-send corrections.
Validate every release. Use GET /delivery/transfers/{transferId} to list them and POST …/validate on each.
Submit the transfer. Nothing is submitted until every release is ready.
Wait for live. Follow each release’s status (see Release status). Store links appear as stores go live.
Then take down at your previous distributor. Only after the releases are live here, so they’re never missing from stores.

Problem	What to do
A track’s ISRC is missing from the export	Ask your previous distributor; don’t create a new one, or stores will see a new recording.
A release went to a new, empty artist profile	Send the artist’s store profile IDs, and contact your AMM Distro representative.
`upc_in_use` or `isrc_in_use`	The code is on another account on AMM Distro. Contact your representative.
Artwork smaller than 1400×1400	Get the original artwork; small images are refused.
