Example Tracker Requests

note

This page gives examples of requests to the Snowplow collector. However, there is no need to perform these requests manually. Instead, we recommend using our Snowplow trackers that do them for you. The requests on this page are only relevant if you plan to write a new tracker implementation.

Below are a number of example Tracker Protocol requests. All examples are POST requests with a JSON body.

All requests are sent to https://<your-collector-host>/com.snowplowanalytics.snowplow/tp2 unless you have specified a custom POST path when configuring your Collector.

All payloads should be wrapped in a payload_data Self Describing JSON.

    {

Self Describing Event​

This is an example of a viewed_product event from the web (using the recommended Base64 encoding and the ue_px property):

Custom Entities​

An array of entities can be sent with each event. Entity payloads should be wrapped in a contexts Self Describing JSON.

  "data": [
    {
      ...
