Artifacts

Upload a catalog artifact

Uploads a catalog CSV as multipart form data and returns an artifact_id for use when starting an optimization workflow.

The HTTP client must set the Content-Type: multipart/form-data header with the appropriate boundary; the header should not be set manually. The domain header is required and must be a brand domain (for example, vessel.com) that the authenticated principal is authorized to access.

Each request creates a new artifact, even when the file content is identical to a previously uploaded file. Retain the returned artifact_id for the workflow that will reference it.

For catalogs larger than approximately 100 MB, contact fabric support to enable the presigned-URL upload flow.

Catalog CSV format

The uploaded file must be UTF-8 encoded, comma-delimited, and include a header row. The supported columns are:

Column	Required	Description
`title`	Yes	Product display name as shown on the product detail page.
`sku`	Yes	Unique product identifier within the brand catalog.
`description`	Yes	Full product description from the product detail page.
`category_id`	Conditional	The brand’s category identifier. Each row must provide either `category_id` or `breadcrumb`.
`breadcrumb`	Conditional	Full category hierarchy separated by `>` (for example, `Mens > Clothing > Pants`). Each row must provide either `breadcrumb` or `category_id`.
`category`	No	Free-text category label. Used as a hint when neither `category_id` nor `breadcrumb` resolves to a known category.
`product_group_id`	No	Identifier shared by product variants that belong to the same family.
`price`	No	Numeric price value for the product.
`currency`	No	Currency code corresponding to `price`.
`url`	No	Canonical product detail page URL.
`images`	No	One or more image URLs separated by the pipe character (`\|`).
`attribute.<name>`	No	Custom attribute value. Free-form string, single value per cell. The `<name>` segment must match an attribute key configured for the brand.

For a worked end-to-end example including auth and workflow creation, see the Product Import Developer Guide.
