"icon": "Webhook",
"schema": {
"properties": {
"key": {

"icon": "DefaultProperty"
"environment_id": {
"icon": "DefaultProperty",
"title": "Environment Id",

"type": "string"
"sdk_version": {
"title": "SDK Version",
"type": "string",
"description": "the SDK version"
"required": []
"mirrorProperties": {},

"relations": {}

Create the following webhook configuration using Port's UI

Split webhook configuration
  1. Basic details tab - fill the following details:

    1. Title : Split Mapper;
    2. Identifier : split_mapper;
    3. Description : A webhook configuration to map Splitio impressions to Port;
    4. Icon : Jenkins;
  2. Integration configuration tab - fill the following JQ mapping:

    "blueprint": "splitImpression",
    "itemsToParse": ".body",
    "entity": {
    "identifier": ".item.key + \"-\" + .item.time",
    "title": ".item.split",
    "properties": {
    "environment_id": ".item.environmentId",
    "environment_name": ".item.environmentName",
    "label": ".item.label",
    "sdk": ".item.sdk",
    "sdk_version": ".item.sdkVersion"
  3. Click Save at the bottom of the page.

Create a webhook in Split

  1. Go to Admin Settings.
  2. Click Integrations.
  3. Select your workspace.
  4. Click Add next to Outgoing Webhook (Impressions).
  5. Check the environments where you would like data sent from.
  6. Enter the value of the url key you received after creating the webhook configuration.
