status. Read one release with GET /delivery/releases/{releaseId}, or many with GET /delivery/releases.
delivered and live are set as soon as the first store has the release. Other stores can take longer, so not every store link appears at once.
Identifiers
upc and each track’s isrc are null until assigned. If you didn’t send them, they’re assigned when the release is approved, and appear once it moves to delivering.
Listing releases
Only releases sent through the API are listed. Releases created in AMM Distro can be looked up by UPC or ISRC with the ingestion check.
Checking for changes
There are no notifications yet; check for changes by polling. Check releases in review or delivery a few times a day; once a release islive, there’s no need to check it often. Stay within your rate limit.
