Configuration
3 fields, 3 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
inventory_item_id Inventory item id, taken from the variant's 'inventory_item_id'. | string | Yes | — | — | 808950810 |
location_id Location whose stock is being adjusted, from shopify.list_locations. | string | Yes | — | — | 655441491 |
available_adjustment How much to add to the current count; negative removes stock. | number | Yes | — | -2147483648–2147483647 | -1 |
Example configuration
Every value below is the contract’s own example or default — nothing invented.
{
"available_adjustment": -1,
"inventory_item_id": "808950810",
"location_id": "655441491"
}Output
One shape.

}Notes
- The store and the API version come from the connection: 'shop' (your-store.myshopify.com) and an optional 'api_version' that defaults to 2026-07. Auth is the Admin API access token, sent as X-Shopify-Access-Token.
- Lists page on an opaque cursor from Shopify's Link header, not on page numbers. Pass the 'page_info' a call returns back into the next call while 'has_more' is true; a request carrying page_info may only carry 'limit' and 'fields', so every other filter is ignored once you are paging.
- Shopify rate-limits with a leaky bucket (X-Shopify-Shop-Api-Call-Limit). A 429 fails the step with the bucket state and the Retry-After seconds in the message: put a control.delay in front of the node or lower 'limit'.
- Each write node also accepts the raw resource object for fields it does not model; that object is merged last and wins on a conflict.
- The delta is applied to whatever the count is when the call lands, so two systems adjusting the same item cannot overwrite each other.
See Adjust Inventory Level run in a workflow.
In a technical demo we add the Shopify connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
