Customiser jackets
Update a jacket
Applies an RFC 7396 JSON Merge Patch to one jacket: properties omitted
from the body are unchanged, and null clears a nullable property
(description). Arrays are replaced wholesale, so sending
excluded_colour_ids replaces the whole exclusion list.
Overview
Read-only and
unknown fields are rejected. An empty object {} is a valid no-op.
Requires customisers:write.
jacket_type may be changed to a type no other jacket of this customiser
holds; switching to one that is taken is a 422 on /jacket_type.
An Idempotency-Key is optional here: sending one makes the update safe
to retry (an exact repeat replays the original response; the same key with
a different body is a 409). The update clears the customiser's cached
storefront configuration and runs the advisory language sync, and never
regenerates Shopify products, product images, or the product cache.
Authorisation
Bearer token required. Include it in theAuthorization header.
Required scope: customisers:write
Path parameters
The customiser id.
Example: 1
The jacket id.
Example: 9
