Get the sizes section

Retrieve the sizes section of the customiser: the heading (title) and the text under it (description) that the customer customiser shows above the sizes. It also publishes border_margin_cm, the default border margin every size uses unless the size sets its own, with its inch twin border_margin_in and authored_units. The sizes themselves are a separate resource. A customiser that has never saved this section reads the defaults (title and description null, border_margin_cm 0) with updated_at null, and the read does not create the section. The operation is read-only, has no side effects, and is always safe to retry. Requires the `customisers:read` scope. A 404 problem with code `resource_not_found` means the customiser does not exist on the store your API key belongs to. A 401 problem means the key is missing, invalid, or expired; a 403 problem with code `insufficient_scope` means the key lacks `customisers:read`; a 429 problem means too many requests: wait `retry_after` seconds, then retry. Error responses use RFC 9457 problem+json with a machine-readable `code` and a `request_id` to quote when contacting support.

Overview

The sizes themselves are a separate resource. A customiser that has never saved this section reads the defaults (title and description null, border_margin_cm 0) with updated_at null, and the read does not create the section.

A 404 problem with code resource_not_found means the customiser does not exist on the store your API key belongs to. A 401 problem means the key is missing, invalid, or expired; a 403 problem with code insufficient_scope means the key lacks customisers:read; a 429 problem means too many requests: wait retry_after seconds, then retry. Error responses use RFC 9457 problem+json with a machine-readable code and a request_id to quote when contacting support.
