mParticle JSON Schema Reference

The mParticle JSON schema defines the structure of all data sent to the mParticle customer data platform from the HTTP API or the platform SDKs (such as the Web, iOS, or Android SDKs).

This same JSON schema also defines the structure of data sent from mParticle to output integrations. There are some differences between the format for inbound and outbound data. For a complete list of these differences, see differences between the inbound and outbound JSON format.

The following document includes several additional explanations and examples. Use the following raw JSON schema definitions for programmatic JSON generation and validation:

See JSON schema validation for information about using these schemas to test and validate data structure.

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": {},
	"schema_version": 2,
	"environment": "production",
	"context": {},
	"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. This value is used internally by mParticle account representatives. It indicates the current schema version a message batch conforms to.
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. The IP address is stored on user profiles and is kept updated with the most recently seen value for each user. `ip` is only forwarded to connected outputs if the `Enrich IP Address` setting is available and enabled for the connection.

`events`

The event object consists of two required 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,
        "location": {},
        "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	Description
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 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.

`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_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:

Contacting mParticle.
Updating your Firehose module, if applicable. For more information, see Firehose — Partner Identities.

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.

`consent_state`

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": {
        "gdpr": {
            "location_collection": {
                "consented": true,

                "hardware_id": null
            }
        }
    }
}

`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
    }
}

Property	Data Type	Description
channel	string	Source the batch was received from. Valid values: “native”, “javascript”, “pixel”, “partner”, “server_to_server”, and “unknown”.
partner	string	If the channel is `Partner`, this field is the name of the partner feed
replay_request_id	string	If data is from a replay, unique ID for the replay request
replay_job_id	string	If data is from a replay, unique ID for the replay job
is_historical	string	If true, data was received via the historical endpoint.

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)
