Standard… Reference for the POST /fulfillments endpoint in the Vault by Stashtab API API. sidebar: badge: POST label: Create a fulfillment title: Create a fulfillment type: openapi-operation --- Address inventory by exact QIDs or SKU-and-quantity lines. Standard fulfillment uses a recipient shipping address; withdrawal uses the organization's primary verified address or a `verified_address_id` and never accepts a free-form address. Everything downstream — allocation, warehouse order, pick, pack, verification, label, and carrier handoff — happens on our side, and progress flows back through `GET /fulfillments/{fulfillment_id}` and the `fulfillment.status.changed` webhook. Send an `Idempotency-Key` header; retries with the same key return the original fulfillment instead of shipping twice.
