## Operations

| Operation | Kind | What it does |
| --- | --- | --- |
| [addSegmentMembers](/reference/pricing/addSegmentMembers/) | mutation | Add up to 48 shoppers to a segment in one call — already-present shoppers are skipped, not errors. |
| [cancelMarkdownPlan](/reference/pricing/cancelMarkdownPlan/) | mutation | Cancel a markdown plan — scheduled price cuts over time. |
| [createCouponBatch](/reference/pricing/createCouponBatch/) | mutation | Mint a batch of unique single-use codes (up to 48) that all unlock one existing coupon’s terms. |
| [refreshSegment](/reference/pricing/refreshSegment/) | mutation | Recompute a rule-based segment’s membership from its rule — shoppers who now match join, shoppers who no longer match leave. |
| [removeSegmentMembers](/reference/pricing/removeSegmentMembers/) | mutation | Remove up to 48 shoppers from a segment in one call. |
| [scheduleMarkdownPlan](/reference/pricing/scheduleMarkdownPlan/) | mutation | Schedule a markdown plan — the price cuts will fire on their dates. |
