Field mapping and sync direction

Integrations work by matching records between Fiddle and the other platform, then moving data in a defined direction for each type.

How records are matched

Products are matched by SKU. Each product on the channel is linked to the Fiddle item whose SKU is identical. If a SKU has no match, that product won’t link and its orders may not draw from the right item.

Keep SKUs identical on both sides — same casing, no extra spaces. Mismatched SKUs are the most common reason products fail to link.

Sync direction

Most integrations sync in both directions, but each data type flows one way.

Data	Direction	Notes
Orders	Into Fiddle	Channel orders become sales orders
Available inventory	Out of Fiddle	Stock is pushed to the channel
Products / SKUs	Matched	Linked by SKU, not overwritten

Fiddle is the source of truth for inventory. Available stock is pushed out to each connected channel so the same units aren’t sold twice across stores.

“Available” — not on-hand — is what gets pushed, since reserved stock is already committed to other orders.

Choosing a stock location

Each sales-channel integration draws from, and pushes back, one location. Pick the location that actually fulfills that channel’s orders so availability stays accurate.
