Webhooks

React when participants complete assessments. HI Platform sends signed HTTPS POSTs to a URL you control, so you can sync results, trigger automation, or update dashboards without polling.

How it works

Register an HTTPS endpoint in HI Platform. When an event happens, we send a signed JSON payload. Your service verifies the signature, returns a 2xx response, and processes the event.

Webhook delivery flow An event in HI Platform triggers a signed HTTPS POST to your endpoint. Platform event in HI Platform Signed HTTPS POST JSON body X-Webhook-Event X-Webhook-Timestamp X-Webhook-Signature X-Webhook-Delivery-Id Your endpoint verify & process
Each delivery carries four headers your service uses to identify and verify the event.
Respond with 2xx to acknowledge. Anything else — non-2xx, timeout, transport error — is treated as a failure and retried.
