Update Metric

(v2)

PUT

Updates a custom metric and returns it. Only the fields you send are changed; send null to clear criteria or evaluationSteps, as long as one of them remains. Every update creates a new metric version.

Response

Update Metric succeeded.

- idstring
  This is the unique id of the metric.
- namestring
  This is the name of the metric, unique within your project.
- algorithmenum | null
  The algorithm the metric is evaluated with. GEVAL scores against criteria or evaluation steps, DAG walks a decision graph, JEVAL asks a decision model bounded questions, PROMPT sends your own judge prompt to the evaluation model, CODE runs your own code, and DEFAULT is a built-in metric.
