Documented steps
POST .../applications/{packageName}/edits (edits.insert) to open an edit.
GET .../edits/{editId}/tracks/{track} (edits.tracks.get) to read the current Track resource before mutating it, because tracks.update is a full replace.
Start the rollout: PUT .../edits/{editId}/tracks/{track} with a release {"versionCodes":["<code>"],"status":"inProgress","userFraction":0.05}. userFraction must be strictly between 0 and 1.
POST .../edits/{editId}:commit to publish the rollout start.
To increase exposure, open a fresh edit and set the same release's userFraction higher (0.1, 0.5, ...) while status stays 'inProgress', then commit.
To halt a bad rollout, open a new edit, set that release's status to 'halted', and commit. This stops serving the release to new users.
To resume, set status back to 'inProgress' with a userFraction and commit.
To finish the rollout to all users, set status to 'completed' and clear userFraction, then commit.
To limit geography on a production staged rollout, set countryTargeting: {"countries":["US","CA"],"includeRestOfWorld":false} on the release object.
Each rollout change is its own edits.insert / tracks.update / commit cycle; there is no long-lived rollout handle.
Known gotchas
Release status enum values are exactly: statusUnspecified, draft, inProgress, halted, completed.
userFraction is valid only while status is inProgress or halted, and must be cleared once status is completed.
countryTargeting is only allowed when the release is inProgress on the production track; it is not supported on internal or closed testing tracks.
inAppUpdatePriority cannot be modified once the rollout has started; set it when the release is first created.
A release acting as the track's serving fallback cannot be halted in certain fully-rolled-out scenarios.
tracks.update (PUT) replaces the entire Track resource. Omitting an existing release removes it. Prefer edits.tracks.patch for a partial change.
Form-factor tracks need a prefix in the identifier, e.g. wear:production, wear:beta, wear:qa, automotive:production, tv:production, android_xr:production, google_play_games_pc:production.
A stale or invalidated edit (from expiry or a concurrent Play Console change) must be reopened with edits.insert; you cannot extend an edit.
