Request

Use the value field matching the evaluator `score_value_type`: `numerical`/`percentage` -> `numerical_value`, `boolean` -> `boolean_value`, `single_select`/`multi_select`/`categorical` -> `categorical_value`, `text`/`comment` -> `string_value`, `json` -> `json_value`.
evaluator_idstringOptional

Evaluator ID. Provide either evaluator_id or evaluator_slug.

evaluator_slugstringOptional

Custom evaluator slug. Provide either evaluator_id or evaluator_slug.

Numeric score value. Use for numerical and percentage evaluators.

string_valuestring or nullOptional

Text score value. Use for text and legacy comment evaluators.

boolean_valueboolean or nullOptional

Boolean score value. Use for boolean evaluators.
