Submit App Plan

Validates a mobile app plan and saves it for approval.

Returns the normalized plan with its revision and digest. Show this plan to the user and, once they approve it, call Approve App Generation with the same revision and digest.

To change a saved plan, call this method again with proposalId and a new requestKey. Each change creates a new revision, and approval of an earlier revision is refused. A plan can have up to 50 revisions. A saved plan expires 24 hours after it's created, at expiresDate.

Repeating a call with the same requestKey and the same plan returns the same result.
