# Versions and availability

> Read webhook schema versions, OpenAPI files and endpoint availability.

Read the version supplied by the interface you use. SDK package versions and webhook schema dates identify their respective interfaces.

## Webhook versions

Each webhook includes `event_type` and `schema_version`. Use both fields to select the event model. See the examples for [`identification.scored`](https://docs.shieldlabs.ai/api/webhook-identification#example-payload) and [`hre.multi_account.changed`](https://docs.shieldlabs.ai/api/webhook-multi-account).

For `identification.scored`, schema `2026-10-13` exposes [20 public detection flags](https://docs.shieldlabs.ai/features/risk-signals.md#source-signals).

## OpenAPI and SDKs

Download the [OpenAPI YAML](https://docs.shieldlabs.ai/references/openapi.yaml) or [JSON](https://docs.shieldlabs.ai/references/openapi.json). SDK packages are installed and upgraded separately.

The [SDK index](https://docs.shieldlabs.ai/api/sdks.md) links to installation guides. Prefer its supported package entrypoints over generated transport examples.
