Events API

JSON Reference

Edit this Page

This document details the mParticle JSON Events format. This format is used to post events to mParticle via the HTTP API. This format is also used to send events to output integrations which accept raw JSON, however there are a few differences between the inbound and outbound JSON format.

JSON Schema

As a supplement to the JSON documentation below, mParticle hosts JSON Schema documents that you can use as a reference and for programmatic JSON generation and validation:

See the validation section for more information on using these schemas.

Overall Structure

{
    "events" :
    [
        {
            "data" : {},
            "event_type" : "custom_event"
        }
    ],
    "device_info" : {},
    "source_request_id":"7fa67be4-f83a-429f-9d73-38b660c50825",
    "user_attributes" : {},
    "deleted_user_attributes" : [],
    "user_identities" : {},
    "application_info" : {},

    "mpid":7346244611012968789,
    "ip" : "172.217.12.142"
}

All properties are optional and support both input and output unless specified otherwise in the Description.

Property Data Type Description
events array An array of JSON objects, each representing an event. The event object consists of two nodes: data, and type. The type indicates the entity structure of the data node.
schema_version integer Output only. Indicates the current schema version that this message batch conforms to. mParticle is currently on version 2.
device_info object A JSON object containing information about the device pertaining to this message batch.
application_info object A JSON object of information about your app.
source_request_id string A value to uniquely identify this request. This is used to deduplicate inbound requests. De-duplication is scoped by API key, found in Organization/Account/Workspace/Inputs, and remains in the system for enforcement anywhere from 30-60 days. Any valid string is accepted.
user_attributes object map String key-value pairs of demographic information about the user that generated the app events.
deleted_user_attributes string array An array of JSON strings describing previously provided user attributes which should be forgotten.
user_identities object map String key-value pairs of user ID information, such as email address and social IDs.
partner_identities object map String key-value pairs of partner identities.
integration_attributes object map String key-value pairs of integration attributes indexed by module.
environment enum string Default value: production. Must be either “production” or “development.”
context object Data planning and location information.
mpid long If known, the unique mParticle identifier for the user, calculated based on user and device identities in the batch, according to your Identity Strategy.
ip string Input only. The IPv4 / IPv6 address of the consumer device.

events

The event object consists of two nodes: data, and event_type. 

{
    "data" : {},
    "event_type" : ""
}

The following event_type are allowed. These values are specified in the type fields within the events node.

event_type Description
custom_event A Custom event with a name and optional attributes.
commerce_event A Commerce event.
session_start Session Start event.
session_end Session End event.
screen_view Screen View.
uninstall App was uninstalled.
crash_report Crash Report.
opt_out User Opt-Out.
push_registration Registration of the device push token.
application_state_transition An event fired when the application starts, exits, comes into foreground, or enters background.
push_message A push message is received.
network_performance An event containing network performance details on external http calls made from the application.
breadcrumb Breadcrumbs are used for crash reporting to understand which events lead up to a crash.

The type indicates the entity structure of the data node in the event. There are also some common elements to all data nodes.

Common event data node properties

{
  "data" :
    {
      "event_id" : 6004677780660780000,
      "event_num" : 0,
      "source_message_id" : "e8335d31-2031-4bff-afec-17ffc1784697",
      "session_id" : 4957918240501247982,
      "session_uuid" : "91b86d0c-86cb-4124-a8b2-edee107de454",
      "timestamp_unixtime_ms" : 1402521613976,

      "device_current_state" : {},
      "custom_attributes": {},
      "custom_flags": {}
    },
  "event_type" : ""
}
Property Data Type Required Description
event_id Int64 Read only Unique ID generated by mParticle server as each event is received.
event_num Int64 Read only, optional for S2S Zero-based number indicating an event’s place within the current session. In a session with a single event, event_num will be 0. The iOS and Android SDKs populate event_num automatically, but for S2S connections developers should manually calculate and populate this value if desired.
source_message_id string suggested Unique Id of source event. Generated by mParticle client-side SDKs for platform data. For session start events, SDKs set this value to session_uuid. If sending data via Events API it is suggested to generate a UUID for each event.
session_id Int64 Read only Unique Id of session.
session_uuid string suggested An optional universally unique identifier for the session. The session_id will be derived from a hash of this value.
timestamp_unixtime_ms Int64 suggested Timestamp of event. The current server time will be used if not specified.
location location JSON optional The location the event occurred in.
device_current_state device_current_state JSON optional An object with a number of properties describing the state the device was in at the time the event was logged. See below for further details.
custom_attributes JSON key value pairs optional A dictionary of custom attributes. If the Event API is called using Custom or Partner feed credentials, the mParticle Source Feed custom attribute is included which contains the name of the input feed configuration. This attribute cannot be filtered.

The details on location and device_current_state will be detailed after additional information on the event_type and the corresponding data nodes.

Attribution custom events

Attribution events are sent to mParticle as custom events with:

Property Value
event_type custom_event
custom_event_type attribution

The custom event_name depends on the Attribution Type:

Attribution Type event_name Desription
Install attribution Install attribution events allow you to attribute the install of your app to a specific publisher and campaign. The publisher and campaign information is stored on the user’s profile and the events are available in the audience builder. Install attribution events require campaign and publisher custom attributes representing the campaign and publisher which are credited for the installation. You should also include as many device and user identifiers as you can.
Re-engagement re-engagement Re-engagement attribution events are typically created when a user opens an app which has already been installed as a result of clicking a deep link. Re-engagement attribution events can also accept campaign and publisher attributes. Re-engagement attribution information is not stored on the user profile.
Engagement any Engagement attribution events allow you to attribute actions (i.e. add to cart, purchase, etc) a user takes in the app to a specific publisher and campaign. Engagement attribution events can also accept campaign and publisher attributes. Engagement attribution information is not stored on the user profile.

custom_flags

{

	{
		"Google.Category": "pageview",
		"Google.Label": "main:mktg:personal::home",
		"Google.Value": "123"
	}
}

Custom flags are:

  • used to trigger behaviors for predefined data-points to a specific integration.
  • sent to the specific integration, and to all raw data event integrations (i.e. Amazon Kinesis, Amazon S3, Amazon SNS, Amazon SQS, Apache Kafka, Google Cloud Storage, Google Pub/Sub, Microsoft Azure Blob Storage, Microsoft Azure Event Hubs, Slack, and Webhook). This differs from custom_attributes, which are will sent to all connected integrations which support generic key/value attributes.
  • cannot be used within an audience definition.

Reference the guide for each integration to see if you need to instrument custom flags. Custom flags are supported by the following partners:

user_attributes

The properties with the prefix ”$” are reserved attributes that drive specific behaviors in our platform. This object can also contain any number of custom user attributes that you can define from within your app. Custom attributes also allow for lists of values instead of scalar values, but in general a given attribute should not change between a scalar and a list in subsequent calls.

"user_attributes":
{
    "$age": "18",
    "$gender": "M",

partner_identities

Partner Identities are unique identifiers associated with a user, but specific to a partner system. They can be ingested by mParticle via Partner Feed or our S2S API, and can be sent to downstream connections associated with the given partner. A Partner Feed can only send in their registered partner identity, whereas a S2S request can include any partner identity.

"partner_identities":
{
   "partner_id": "1234",
}

Registering a new Partner Identity

Before a partner’s unique identity can be ingested, it must be registered with mParticle. Partners can register a new identity by either:

The naming convention for these identities is as follows: PartnerName_IdentityName. An example for mParticle could be: mParticle_mpid

integration_attributes

Integration attributes are unique values associated with a given user, for a given integration. They are generally required for the integration to function properly.

The JSON blob is indexed by Module ID, meaning each integration can have its own values:

"integration_attributes": {
  "123": {
    "someIntegrationAttribute":"value"
  }
}

In order to find out a given integration’s ID, you can check the corresponding URL from the mParticle Directory.

Used to communicate the GDPR consent state for the user. For GDPR, you must define the purposes (shown here as location_collection and parental) in the mParticle UI. For CCPA, only the below purpose is allowed and it does not need to be defined. Pass consented: true to register a users opt-out to CCPA data sale.

"consent_state": {

source_info

This node is populated automatically by mParticle on receiving a batch. You do not need to send source_info.

This node is available in the mParticle Rules environment, but all values are immutable.

"source_info": {
	"channel": "server_to_server",
	"partner": null,
	"replay_request_id": null,
	"replay_job_id": null,
	"is_historical": true
}

Differences between incoming and outgoing JSON

Described above is the format required for sending data to mParticle via the Events API. A very similar format is used to send data to event outputs that accept raw JSON, including:

For these forwarders, mParticle makes our output as complete as possible, including fields only used internally or fields that are set automatically by mParticle and not part of the inbound JSON reference. The most important difference between incoming and outgoing JSON is that the user_identities field is expanded in the outgoing JSON to include additional information. In most other cases, additional fields added in the outgoing JSON are intended for internal use or to support edge cases and should be ignored unless you have a special need for these fields.

Some notable differences include:

  • mParticle may add identifiers for the batch (batch_id), and each event (message_id). These are used by mParticle for internal processing tasks like de-duping.
  • mParticle adds a message_type field to each event, which is used for internal processing.
  • mParticle may add session management fields to each event: session_id, session_uuid and session_start_unixtime.
  • Outbound JSON will include an event_start_unixtime_ms field. In almost all cases this will be the same as the main event timestamp_unixtime_ms field. It exists to support timed event use cases.
  • mParticle adds a top-level batch timestamp — timestamp_unixtime_ms — representing the time the batch was received by mParticle. This field is created by mParticle and should not be set manually when sending data via the Events API.
  • Some fields are set automatically by one or more native SDKs. For example, the Android SDK automatically sets an activity_type of activity_started or activity_stopped on Screen View events. This field is used by some event integrations to determine how to forward the event.
  • The system_notifications field is currently used by mParticle to forward changes in consent state to some partners. In outbound JSON this field is present but empty unless you are instrumenting data privacy controls.
  • mParticle may add a top-level batch unique_id field if you enter a value for the Unique ID connection setting.

Outgoing User Identities

In outgoing JSON, the user_identities node is an array of identity objects. Each object contains the identity type, the value, and a timestamp showing when the identity was last updated. For example:

 "user_identities": [
   {
     "identity_type": "customer_id",
     "identity": "h.jekyll.md",
     "timestamp_unixtime_ms": 1540483995196
   },
   {
     "identity_type": "email",
     "identity": "h.jekyll.md@example.com",
     "timestamp_unixtime_ms": 1540483995196
   }
 ],

JSON Schema Validation

mParticle’s server-side SDKs are designed to generate correct JSON in all cases. If you are unable to use mParticle’s SDKs, you can use the mParticle Events API JSON schema documents to validate your JSON prior to upload.

Python

The following example uses the popular jsonschema library and performs the following:

  • Downloads the latest Event API schemas (both the single and bulk variations)
  • Creates an arbitrary example upload as a dictionary
  • Validates both the single and bulk instance objects
from jsonschema import validate, exceptions
import urllib.request, json

schema_url = "https://docs.mparticle.com/schema/mparticle.inbound.eventsapi.schema.json"
url = urllib.request.urlopen(schema_url)
schema = json.loads(url.read().decode())

bulk_schema_url = "https://docs.mparticle.com/schema/mparticle.inbound.eventsapi.bulk.schema.json"
bulk_url = urllib.request.urlopen(bulk_schema_url)
bulk_schema = json.loads(bulk_url.read().decode())

# Create a dictionary to be validated
instance = {
    "source_request_id":"769D83CB-8C60-48F9-A0C1-C38CF1B40A4F",
    "device_info": {
        "ios_advertising_id":"1cc8138f-8aaf-410a-b0b9-6465cfb2af6a",
        "ios_idfv":"0f129dcb-d5b9-450b-9003-a38a7b7e946d",
        "att_authorization_status":"authorized",
        "att_timestamp_unixtime_ms":1614187122051
    },
    "user_attributes":{ "Test attribute":"Test value" },
    "user_identities":{ "customer_id":"123456" },
    "environment":"production"
}

# You can also load an existing JSON string into a dictionary
# instance = json.loads("{}")

# If you're sending via the bulk endpoint, create an array of batches
bulk_instance = [instance]

try:
    # If your JSON is badly formed, this will throw a ValidationError
    validate(instance=instance, schema=schema)
    validate(instance=bulk_instance, schema=bulk_schema)
except exceptions.ValidationError as e:
    # Read more on ValidationError objects here:
    # https://python-jsonschema.readthedocs.io/en/stable/errors/
    print(e.message)
    print(e.path)
