seo:write/api/v1/seo/keywords/fieldsRequest body
locationIdstringrequired
ID of the location whose field set you're changing. For AEO prompts, the website.
mutationIdstringrequired
A UUID you choose for this change. Resending it with the same command returns the first result without applying the change again; reusing it with a different command returns 409.
commandobjectrequired
One change. field_create adds a field with label, type and options. field_update renames a field, changes its options, or archives or restores it, and needs the field's current version as expectedVersion. values_update sets 1 to 1000 values, each with recordId, fieldId, value and expectedVersion, and applies all or none. An option that records still hold can't be removed; archive it instead. A field set holds at most 40 fields, archived ones included.
Response
