Prewave

This document contains the changelog and release notes for the Prewave Public API for March 2026. This month’s update is headlined by the upcoming launch of the Feed API v2, designed to provide more structured alert data with enhanced performance.

___________________________________________________________

Endpoint: <code>GET /public/v2/feed</code>

The new Feed API delivers the same alert data as the dashboard feed but with a cleaner contract and better throughput.

Tier Control: New <code>minTier</code> and <code>maxTier</code> parameters allow you to scope alerts to specific supply chain levels (e.g., Tiers 1–3).

Standardized Dates: Uses UTC ISO 8601 format for the <code>from</code> parameter.

Structured Metadata: Replaces the flat <code>infotags</code> list with structured fields like <code>eventTypes</code>, <code>eventTypeGroups</code>, and <code>alertTypes</code>.

Automatic Lookback: If the date is omitted, the API now defaults to returning the last 90 days of data.

Response Timestamps: All response timestamps (e.g., <code>createdAt</code>) are now returned as ISO 8601 strings rather than numeric milliseconds.

Existing integrations should note the following changes when moving to the V2 endpoint:

Feed v1 remains supported, but we recommend all new integrations use Feed v2 starting 19 March 2026.

The following features are currently in development:

📊 External Score Ingestion API: Push external scores to Prewave in an auditable way.

🔍 Supplier Screening (V2): Request history screening and check status via Supplier Site V2 endpoints.

✅ Supplier Validation (V2): Improved flow for requesting supplier discovery and validation.

📂 Enhanced Supplier Lookup: Find-by-identifier responses will be expanded to include industries, collections, and connections in a single call.
