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.
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.
