plan.sold_out
A plan hit its sales cap, or a pass series filled its last seat, and Subscriby paused it automatically.
When this fires
A plan carrying a sales cap records its last allowed successful purchase, or a pass_series plan with a seat cap seats its last holder. Subscriby switches the plan off on the spot, records the reason, and fires this event once. The plan disappears from the portal and the bot until the creator switches it back on; existing subscribers are untouched.
A plan.deactivated event fires alongside it, carrying the same reason, so automations that only watch availability still see the change. Subscribe to this event when you care specifically about "sold out": a waitlist, a restock reminder, a celebratory post.
Switching the plan back on from the dashboard, the API (publish) or the
publish_plantool clears the reason and, for a sales cap, restarts the counter at zero, so the same cap sells another batch. Raising or clearing the cap while the plan is on sale also restarts the counter. A seat-capped series keeps its seats taken; raise the seat cap before publishing it again.
