  - Allowed values: `text`, `number`, `boolean`, `date`, `color`, `url`, `image_url`, `rss_feed_url`, `json`
- `value_source` (enum, required) — Where the value for each publication comes from.
  - Allowed values: `static`, `fetched`
- `response_keys` (list of PublicationFieldResponseKey, required) — The keys declared within the fetched JSON response body. Empty unless `kind` is `json`.
