When a unit of each SKU is likely to be in hand
GET /restock-eta
When a unit of each SKU is likely to be in hand (sku, or skus comma-separated, up to 200): first the earliest open purchase order whose outstanding units are not already taken by the SKU's backorders (basis: inbound-po), at its projected arrival — a carrier ETA, the expected day moved by the supplier's lateness, or the SKU's own lead-time estimate from the day placed; else, if ordered today, the lead-time estimate of the SKU's priced supplier, or the soonest supplier (reorder-lead-time); else none.
A lead-time estimate weighs each past delivery by its age (the organization's leadTimeHalfLifeDays) and shrinks a SKU with little history toward its supplier's other SKUs (leadTime: expected days, p10/p50/p80/p90, effective sample, the factors used). availableOn with its band (earliestOn–latestOn), daysAway, confidence and the supplier; backordered is what the inbound supply was netted against, absent when inventory did not answer. Precomputed in the background as facts land and daily; a SKU never asked about is computed on the spot.

}The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web
page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: purchasing-manager.openapi.json. Base URL https://purchasing.getmanifold.io.
