VAS Costs

Per-VAS, per-tag pricing. Updates propagate to channel_value_added_service and listing_channel_value_added_service. Supports single, bulk, and CSV upload/export.

📄️ List VAS costs (paginated)

Returns a page of VAS cost rows. Default size is 20. When `vasId` is supplied, all matching rows are returned without pagination (cardinality is naturally small — one row per tag × optional variant).

📄️ Upsert one VAS cost

Sets the (vasId, variantId?, tagName) row. For simple strategies (FIXED / PER_PERSON / PER_ITEM / PER_QUANTITY / PER_HOUR / PER_KM) the `price` column alone is enough. Complex strategies (BASE_PLUS_OVERAGE, TIERED, ON_ACTUALS) carry their parameters in `pricingConfig`. Updates propagate to listing_channel_value_added_service via FK.

📄️ Export all VAS costs as CSV

Streams `vas_costs.csv`.

📄️ Download a CSV template

Streams `vas_costs_sample.csv`.
