set_coupon_listed
shallowdev.sparkpay/sparkpay · Verify this server
Show, hide or SCHEDULE an EXISTING coupon on the public pricing pages by setting its `listed` flag and optional `listed_from` start date. WRITE, human-gated: a real write requires an elicitation-capable client and the human sees the code, the discount, which way it is moving and any start date; clients without elicitation are refused (dry_run works anywhere). These are deliberately the ONLY fields an agent can change on a live coupon: the percent, expiry and tier scope are terms somebody may already have been quoted, while `listed`/`listed_from` are purely a display decision. Together they decide whether the public coupons API returns the code today, which is what every app's promo bar draws from; the discount itself does not move and no Stripe object is touched. `listed_from` in the future STAGES a seasonal coupon so it appears on its own date with no cron: it never blocks anyone holding the code from redeeming it, it only holds the code back from the promo bar. Listing with no `listed_from` clears any existing schedule (lists now). Listing an INVITE-ONLY coupon is refused outright, since that would advertise a near-free code to people who cannot redeem it. A `listed_from` with listed:false is refused as a contradiction. Listing an expired/maxed coupon, or scheduling a start at or after expiry, is allowed but warns. A coupon already in the requested state reports `noop`. Use list_coupons first to see codes and their current visibility.
