Reopen a cancelled campaign
Reopens a cancelled campaign within the 60-day reopen window. The audience, template, channel, and steps are preserved, so reopening flips the row back to draft, zeroes the runtime counters, clears the lifecycle clock, and snapshots the prior run under metadata.previous_runs. Use it to relaunch a recently cancelled campaign without recreating it. Past 60 days the route returns 409 REOPEN_WINDOW_EXPIRED and you must clone the campaign instead. No request body is required.
