customAttributes property
A list of custom (merchant-provided) attributes.
It can also be used for submitting any attribute of the data specification
in its generic form (for example, { "name": "size type", "value": "regular" }). This is useful for submitting attributes not explicitly
exposed by the API. Maximum allowed number of characters for each custom
attribute is 10240 (represents sum of characters for name and value).
Maximum 2500 custom attributes can be set per product, with total size of
102.4kB. Underscores in custom attribute names are replaced by spaces upon
insertion.
Optional.
Implementation
