Preview Trace

August 3, 2026 · View on GitHub

Use case

Returns rule/volume decision traces captured from /routing/evaluate. The route name remains /analytics/preview-trace for transport compatibility even when the UI labels these as decisions.

Authentication

Protected. Send either Authorization: Bearer <jwt_token> or x-api-key: <api_key>. In sandbox, also send x-feature: decision-engine.

For local development, start with:

export BASE_URL=http://localhost:8080
export AUTH_HEADER="Authorization: Bearer <jwt_token>"
export TENANT_HEADER="x-tenant-id: public"
# Sandbox only:
# export BASE_URL=https://sandbox.hyperswitch.io
# export FEATURE_HEADER="x-feature: decision-engine"

Example

Rule decision traces

curl "$BASE_URL/analytics/preview-trace?range=1d&page=1&page_size=10&route=routing_evaluate" \
  --header "$AUTH_HEADER" \
  --header "$TENANT_HEADER"

Open one decision trace

curl "$BASE_URL/analytics/preview-trace?range=1d&payment_id=volume_decision_001" \
  --header "$AUTH_HEADER" \
  --header "$TENANT_HEADER"

Response

/analytics/preview-trace returns the same envelope as /analytics/payment-audit (a PaymentAuditResponse), scoped to rule/volume preview events (route defaults to routing_evaluate).

Notes

  • Analytics reads are ClickHouse-backed and merchant-scoped by the authenticated context.
  • Use range=15m|1h|12h|1d|1w or start_ms plus end_ms for a custom window.
  • Freshly inserted ClickHouse events can take a short moment to become queryable.
  • This endpoint is used for rule/volume decision inspection, not auth-rate transaction scoring.
