Returns

Create or Update (PUT)

Use PUT /v1/metrics to upsert a metric. If a metric with the same name exists, OpenMetadata updates it; otherwise, it creates a new metric. The request body is the same as for POST.

Bulk Create or Update

Use PUT /v1/metrics/bulk with an array of create requests. Add ?async=true to process the request asynchronously.

curl -X PUT "{base_url}/api/v1/metrics/bulk?async=false" \
  -H "Authorization: Bearer {access_token}" \
  -H "Content-Type: application/json" \
  -d '[
    {"name": "customer_retention_rate", "metricType": "RATIO"},
    {"name": "monthly_recurring_revenue", "metricType": "SUM"}
