Selloff works with it through CSV files, so no API key is needed. ## Before the sale - **Catalogue export.** From the catalogue or the sale, open **Export (Templates)** and choose **AuctionMobility - Pre-Auction (CSV)**. Each lot comes with its number and letter suffix, title, description, estimates, reserve, starting price, category, buyer's premium and image links. Columns such as artist, medium or provenance can be mapped to your own fields in the template. - **Registrations.** Under **Import bids**, choose **Auction Mobility Registrations** and upload the registrations file: each bidder is linked to a client, or created as one, and receives a bidder number for the sale. ## After the sale Choose **Auction Mobility Results** and upload the registrations and lots files of the same Auction Mobility sale. Every sold lot is recorded as a sale for its winning bidder at the sold price, ready for [automatic invoicing](https://www.selloff.auction/features/automatic-invoicing.md); fees set on the Auction Mobility bid origin are added to the buyer's invoice. The **AuctionMobility - Post-Auction (CSV)** template then exports prices realised and lot status (sold, passed, withdrawn). ## Bidder matching A review screen comes before every import. Selloff matches each bidder by the Auction Mobility customer ID stored on the client record, then by email address, and otherwise suggests similar clients or a new contact. The Auction Mobility paddle number can be kept as the Selloff [bidder number](https://www.selloff.auction/features/bidder-management.md). An administrator sets the bidder type, bid origin and client external reference once in **Settings › Integrations › Auction Mobility**; the imports appear once that reference is chosen.

No. The integration works with CSV files. You export your lots from Selloff with the Auction Mobility templates and upload the file to Auction Mobility, then import the registrations and lots files exported from Auction Mobility into your Selloff sale. No API key is needed. ### What is the difference between the Auction Mobility registrations import and the results import? The registrations import brings in the bidders registered for your sale, without bids, so that they have a client record and a bidder number before the sale. The results import is used after the sale: it reads the registrations file and the lots file of the same Auction Mobility sale and records every lot sold to an Auction Mobility bidder as a sale, ready for invoicing. ### Can Selloff keep the paddle numbers used on Auction Mobility? Yes. With **Preserve platform bidder number**, each bidder created from an Auction Mobility import keeps their Auction Mobility paddle number as their Selloff bidder number, so numbers match on both sides. If that number is already held by another client in the sale, the import reports it for that bidder instead of creating a duplicate.
