HTTP API

This page document the HTTP APIs. These APIs are used by websites, servers or mobiles application to produce events.

You may want to take a look at the tracking script to add analytics to your website instead of directly interacting with the HTTP API.

Events API​

Request to events API are rate limited by IP address (max 60 events per minute) and standard 429 Too Many Requests responses are returned if limit is exceeded.

Page View Events​

You can create page view events using the following operation: POST /api/v1/events/pageviews.

  • Origin header MUST contain origin of request. This is automatically added by browsers.

  • X-Prisme-Referrer or Referer (with single r typo) header MUST contains URL of viewed page.

  • X-Prisme-Document-Referrer header MUST contains client referrer, URL from which viewer comes from, if present.

  • User-Agent header MUST contains client User-Agent. This is used to determine browser and device.

  • X-Forwarded-For or value of PRISME_PROXY_HEADER option header (if PRISME_TRUST_PROXY is true) to determine client IP address. This is used to determine clients location. Typically, reverse proxies (such as Envoy used by Prisme Cloud) adds this header.

  • X-Prisme-Visitor-Id header MUST contains a unique visitor id, if present.

NOTE: Do not use personal information such as an email address as visitor ID.

Server return 400 Bad Request if URLs from headers are invalid or origin is not registered.

  • X-Prisme-Referrer or Referer (with single r typo) header MUST contains URL of page that triggered the event.
