Oracle CrowdTwist Commerce (POS) API is one of 2 APIs that [CrowdTwist](https://apis.io/providers/crowdtwist/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Commerce, Point-of-Sale, Receipts, and Fulfillment. The published artifact set on APIs.io includes API documentation.

The point-of-sale side of CrowdTwist, served from a separate templated host. Purchase posts a receipt with line items, tenders and coupons and returns the per-item point breakdown including bonus-campaign multipliers; Fulfillment marks a redemption shipped; Return reverses points for a returned purchase. Authentication is the client API key in an X-CT-Authorization header — HMAC signing is explicitly NOT supported on this host. The receipt_id field is documented as a unique identifier per request and duplicates are rejected, which makes Purchase the only de-duplicated write in the platform.
