Prepare. Review. Decide.
Pairwise narrows the work to a selected catalogue, shows the evidence it found, and leaves publication in the merchant’s hands.
Choose a catalogue scope
“Scan my store” starts preparation. If a result or scope failure appears, use “Change range” to choose the entire catalogue or an eligible collection.
Review the evidence
Inspect supported pairings and keep any unresolved case out of publication. A review cannot supply a missing fit detail.
Save, then publish
Save the Pairwise theme embed in Shopify. Publish reviewed offers separately when you are ready.
Open the theme editor, then use Shopify’s Save.
Return to Pairwise and use Publish all N for the offers you reviewed.

Evidence before a suggestion.
Sources are useful only when the details support the relationship. Here, the matching cap stays supported in the synthetic example; the Travel Cap remains held while its fit details are missing.
One pair, with its source details.

Check the catalogue and source boundaries.
The first pass is limited to a selected set of products and the eligible links in their descriptions.
Selected catalogue
Up to 40 variants and 30,000 UTF-8 bytes across the selected catalogue payload. A selected collection can include up to 40 products.
Sources
Eligible links contained in selected product descriptions. Product-page highlights and unlinked manufacturer pages are outside that source path.
Preparation
Preparation is subject to available service capacity.
Placement is checked by theme and surface.
Three separate checks cover the product page, cart page and cart drawer on Horizon 4.2.0. They do not establish behavior on every theme version or cart implementation.
Theme and placement supportProduct page
Checked on Horizon 4.2.0The optional add-on rendered on the product page, responded to keyboard input and was added with the main product action.
Cart page
Checked on Horizon 4.2.0One cart-page Add added the accessory; a page reload verified it and removal restored the earlier cart baseline.
Cart drawer
Checked on Horizon 4.2.0The drawer displayed Add and No thanks; one Add added the accessory, and quantity controls and removal were checked.
Other themes, versions and placements are not established by these Horizon checks. Verify the exact theme, version and placement before relying on it.
Know the plan and usage basis.
Review the plan terms before installation. Catalogue scope and preparation capacity are separate limits.
