Request a send approval

Holds a direct send, campaign send, or schedule for the account owner's approval in Migma and sends nothing. Migma checks the send as it would go out now and returns a summary with an approval link. The owner sends, schedules, or declines it on migma.ai; Migma checks it again then and refuses it if anything that decides who gets it, from whom, or when changed. Direct sends are marketing unless transactional is true, which is refused for tag and segment sends and needs a verified transactional sending identity. Requires API key with email:send (send_email) or campaign:write (campaign actions).
