Customiser colours
Update a colour
Applies an RFC 7396 JSON Merge Patch to one colour: properties omitted
from the body are unchanged, and null clears a nullable property
(description, hexcode, multi_colour_hexcodes, min_width_cm,
min_height_cm). Arrays are replaced wholesale.
Overview
Read-only and unknown
fields are rejected — sending one at all is a 422, whatever its value. An
empty object {} is a valid no-op. The patched result must still be
renderable: clearing the last hex value of a single colour, or switching
to multi/flow without hex values, is a 422 colour_value_required,
and switching to the custom_texture finish is refused with a 422
texture_image_required unless the colour already carries a texture
image. Requires customisers:write.
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
