Use this endpoint to populate or extend the fixed list of allowed values for a content property. The target property must already have a domain of values defined — this endpoint cannot create a new domain. Property values are case-sensitive: Brochure and brochure are treated as distinct values. A maximum of 100 values can be added in a single request.

Warning: Adding values to a content property that does not have a domain of values defined can result in data loss. To enable this functionality, first create a domain of values by logging into Seismic before using this API endpoint.

Glossary: content property — A metadata attribute that can be attached to library content items for classification and filtering. domain of values — The fixed enumerated list of allowed values for a content property.

End of Life

Content Properties are being phased out in favor of the more robust Custom Properties. We will continue to support Content Properties for many months, but you should be using Custom Properties moving forward.
