Reskale terms

Connection — stored authorisation for a marketplace. Either OAuth or a browser session. More.

Import — pulling your existing live listings into Reskale.

Sync — pulling current sales, offers, messages and shipments.

Link existing listing — telling Reskale about a listing you posted by hand. Links only; never creates or edits.

Mark as sold — recording a sale that happened outside a connected marketplace, which also makes the item's other listings eligible for the auto-delist sweep.

Offer to likers — a discounted offer sent to the buyers who liked a listing, on Mercari and Depop. Reskale sends it from Buyer Discounts.

Offer to favouriters — Vinted's discount to people who saved your item.

Business policies — eBay's saved payment, shipping and returns terms, referenced by listings rather than restated on each.

Consolidated shipping — Mercari combining several items into one shipment, keyed by order rather than item.
