You probably don’t need this endpoint. The recommended path is the inline product field on POST /try-on — same upsert semantics, one less call. Use this endpoint only when you want:
  • a lifetime TTL by default (inline upserts default to 15 days),
  • the product listed in GET /products and visible in the dashboard,
  • to pre-register a catalog without immediately running a generation.
Creates or updates a product, matched on (account, externalId). The same endpoint handles both — pass full fields the first time, then partial fields to edit later. Products created via this endpoint default to lifetime (no expiry); pass validForDays to opt into a TTL.

​
Content types

  • application/json — when all images are URLs.
  • multipart/form-data — when you ship image bytes inline. The JSON payload arrives in a data form field; each images[].fileKey references a file field by name.

​
Request

​
externalId
string
required
Your product ID. Reused on subsequent calls to update the same product. Don’t start it with _anon_ — that prefix is reserved for IDs we generate.
​
title
string
Optional. Helps the AI classify the product category more accurately. Preserved on updates if omitted.
​
description
string
Optional. Helps the AI classify the product category more accurately. Preserved on updates if omitted.
​
images
array
Replaces the full image list on update. Each entry has a source object holding exactly one of:
  • url — remote URL.
  • fileKey — name of a multipart file field in the same request.
An optional classifications object can sit alongside source.
The old flat shape — { url } / { fileKey, classifications } with the fields at the top level — is still accepted but deprecated. Prefer { source: { url | fileKey }, classifications? }.
​
validForDays
integer | null
How long the product lives between uses, in days. Defaults to null (kept forever) when created via this endpoint. Pass a number (1–365) to set a custom lifetime, null to opt back into “kept forever” on an existing product, or omit to preserve the existing value.
​
metadata
object
Free-form JSON returned on GET /products/:externalId.
​
imageUrls
string[]
deprecated
Legacy alias for images: [{ source: { url } }, …]. Still accepted; will be removed in the next major. Prefer images.

Response

Returns the full product state after the upsert. See List Products for the field-by-field reference.
