Changelog

Public API and documentation changes.

2026-06-25

Docs restructure (HF-291). Migrated from a flat concepts/guides/api tree to an entity-first information architecture (Stripe-style). Each resource now has an overview page and per-method generated pages in the same folder. Webhooks are three hand-written pages instead of per-event generated stubs.

  • New top-level pages: Response Format, Amounts & Precision.
  • Webhook events consolidated into a single Event Types reference page.
  • Signature verification page updated with Python and Node.js verifier examples.
  • All URLs updated to canonical api.thehalfin.com / api-sandbox.thehalfin.com.

Previous

  • Auth and checkout UI endpoints are hidden from public merchant documentation.
  • Merchant, public data, and webhook event references are generated from the public OpenAPI surface.

Event Types

All 13 subscribable webhook events with when they fire and their payload fields.
