The Contentsquare tracking tag sends HTTP requests to several endpoints to collect pageviews, events, transactions, errors, and Session Replay data. Endpoints written as `<...>` are set per project in the Tag configuration rather than being fixed domains. ## Pageview **Endpoint** `https://c.contentsquare.net/pageview` **Trigger** Tag execution and when the `trackPageview` command is called **Method** `POST` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/sending-pageviews/#verifying-the-sending-of-pageviews) ## Events **Endpoint** `https://c.contentsquare.net/v2/events` **Trigger** [See dedicated section for more details](https://docs.contentsquare.com/en/web/events-handling/#verifying-the-sending-of-events) **Method** `POST` **Protocol** `HTTP/2` **Type** `xhr`, and `beacon` when the batch is flushed as the page unloads **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/events-handling/#verifying-the-sending-of-events) ## Quota **Endpoint** `https:///.json` The dynamic configuration domain is set per project in the Tag configuration. **Trigger** For projects with quotas enabled, at the beginning of the session. The Tag reads the project's quota file to decide whether the project still has credits to collect the current session for analytics and for Session Replay. **Method** `GET` **Protocol** `HTTP/2` **Type** `json` **Additional information** There are no request parameters for the quota request. The response is cached for 15 minutes, so the file is not re-fetched on every pageview. If the request fails or times out, the Tag falls back to collecting the session rather than dropping it. ## Transaction **Endpoint** `https://c.contentsquare.net/transaction` **Trigger** When the `ec:transaction:send` command is called **Method** `GET` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/sending-ecommerce-commands/#verifying-the-sending-of-transactions) ## Dynamic variable **Endpoint** `https://c.contentsquare.net/dvar` **Trigger** When the `trackDynamicVariable` command is called **Method** `GET` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/sending-dynamic-vars/) ## Page Event **Endpoint** `https://c.contentsquare.net/pageEvent` **Trigger** When the `trackPageEvent` command is called **Method** `GET` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/custom-page-events/#verifying-the-sending-of-page-events) ## Session Replay Data Collection **Endpoint** * Projects on Advanced Data Collection Pipeline: * `https://k-aeu1.contentsquare.net/v2/recording` (Europe) * `https://k-aus1.contentsquare.net/v2/recording` (US) **Trigger** When session data collection is enabled according to ratio defined in the settings **Method** `POST` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** [See dedicated section for more details](https://docs.contentsquare.com/en/web/personal-data-handling/#session-replay-testing) ## Non publicly accessible resources collection The collection of data URL, non-public, or remote resources by the Tag triggers these requests during session data collection. **Endpoint** * `https://srm.ba.contentsquare.net/exist` (Europe/AWS) * `https://srm.ba.contentsquare.net/putTag` (Europe/AWS) * `https://srm.aa.contentsquare.net/exist` (Europe/Azure) * `https://srm.aa.contentsquare.net/putTag` (Europe/Azure) * `https://srm.bf.contentsquare.net/exist` (US/AWS) * `https://srm.bf.contentsquare.net/putTag` (US/AWS) * `https://srm.af.contentsquare.net/exist` (US/Azure) * `https://srm.af.contentsquare.net/putTag` (US/Azure) **Trigger** When data URL resources or resources behind authentication are found on the website. **Method** `POST` **Protocol** `HTTP/2` **Type** `fetch` ## E-Merchandising **Endpoint** `https://c.contentsquare.net/display` **Trigger** When the E-merchandising tracking is enabled for the project. **Method** `POST` **Protocol** `HTTP/2` **Type** `xhr` **Additional information** 1 request per pageview ## JS Errors **Endpoint** `https://c.contentsquare.net/errors` **Trigger** When JS Error tracking is enabled for the project.
