Shopify store URLs

storeUrls

Required

Store base URLs, e.g. https://www.allbirds.com. Paths are ignored; only the public /products.json catalog is read.

Max products per store

maxProductsPerStore

Optional

Stop after this many products per store (250 per request). If a store has more, that store's run is marked truncated and removed variants are not reported for it.

Type:integer

Maximum:50000

Default:5000

Fields to track

trackFields

Optional

Which variant fields produce change rows. New and removed variants are always reported. Default: all.

[
  "price",
  "compare_at_price",
  "available",
  "title",
  "sku"
]

Snapshot key

snapshotKey

Optional

Optional name for the saved snapshot this run compares against. Leave empty to derive it from the store list, so the same list always compares with its own previous run. Set it to keep history when you edit the list.

Type:string | null

Webhook URL

webhookUrl

Optional

Optional. When a run finds changes, POST the run summary and up to the first 500 changes as JSON here (10 s timeout; a failure is logged, the run still succeeds). Baseline runs do not call it.

Include unchanged variants

includeUnchanged
