Use `event_id` as the URL path parameter. This API method is scoped to a request, i.e. all returned information is by `event_id`. ## OpenAPI ````yaml get /events/{event_id} openapi: 3.1.1 info: title: Server API description: > Fingerprint Server API allows you to get, search, and update Events in a server environment. It can be used for data exports, decision-making, and data analysis scenarios. Server API is intended for server-side usage, it's not intended to be used from the client side, whether it's a browser or a mobile device. The API also supports collection of Automation Intelligence for requests to your server in edge, pre-origin, or middleware contexts. version: '4' contact: name: Fingerprint Support email: support@fingerprint.com license: name: MIT url: >- https://github.com/fingerprintjs/fingerprint-pro-server-api-openapi/blob/main/LICENSE servers: - url: https://api.fpjs.io/v4 description: Global - url: https://eu.api.fpjs.io/v4 description: EU - url: https://ap.api.fpjs.io/v4 description: Asia (Mumbai) security: - bearerAuth: [] tags: - name: Event description: | Get, update, or search for information about events. paths: /events/{event_id}: get: tags: - Events summary: Get an event by event ID description: > Get a detailed analysis of an individual identification event, including Smart Signals.
