HI Developers

Guides, references, and contracts for integrating with HI Platform from your own systems. Start with the section that matches what you're building.

What you can build

Webhooks — Receive signed HTTPS events when participants complete assessments. Useful for syncing results into your ATS, updating dashboards, or triggering downstream automation. No polling required.

Conventions

• All endpoints and webhooks use HTTPS.
• JSON payloads with ISO-8601 timestamps in UTC.
• UUIDs are rendered as strings.
• Receivers must tolerate unknown fields — new fields are added without bumping the contract version.
