Amplitude provides product analytics that helps companies leverage cross-platform behavioral data to drive user growth.

Supported Features

• Analytics
• Data Export
• Real-Time Dashboards
• Retroactive Funnels

Prerequisites

To activate mParticle’s integration with Amplitude, you need the Amplitude API Key for each app that you’d like to set up. Your API key is listed on the Amplitude Project Settings page.

Data Processing Notes

mParticle will forward User Identities and Attributes to Amplitude, even if there are no events in the batch.

Device/User ID Mapping

Every event in Amplitude has a main Device ID field. mParticle populates this field as follows:

• For Android, the Android ID (falling back to the Android Advertising ID if unavailable)
• For iOS, the IDFA (falling back to the IDFV if unavailable)
• For Roku, the Roku Advertising ID (falling back to the Roku Publisher ID if not available)
• For FireTV, the Fire Advertising ID.

Amplitude also has dedicated fields for particular Device IDs, such as IDFA and Android ID. These will be populated if the ID is available. See Field Mappings, for more information.

Amplitude requires either a Device ID or a User ID. User ID can be mapped as Email, Customer ID or mParticle ID. If no accepted identifiers are present, data will not be forwarded.

Forwarding Web Data

By default, mParticle forwards web data to Amplitude client-side, by directly invoking Amplitude’s Javascript methods. Optionally, you can choose to forward web data server-to-server in the Connection Settings. Note that if you choose this option, your incoming data must have your selected User ID to be forwarded.

Data Localization

By default, mParticle sends data to the Amplitude organization’s US endpoint for the HTTP API, but Amplitude offers a different endpoint for EU organizations. In mParticle, the Amplitude Organization Configuration Setting allows you to select a target Amplitude organization location.

Event Data Mapping

Screen Views

mParticle will forward all screen views to Amplitude with the Amplitude Event Type set to “Viewed ScreenName”, where ScreenName is the screen name passed to the logScreen SDK method (or the name of the screen’s Activity class if you’re using automatic screen tracking on Android).

Session Forwarding

mParticle will forward all session start and session end events to Amplitude with the Amplitude Event Type set to session_start and session_end.

eCommerce Event Forwarding

Each valid eCommerce event sent to mParticle is expanded into multiple events before being translated and forwarded to Amplitude. While this expansion applies to all eCommerce transactions, the resulting events are dependent on the type of eCommerce event being forwarded and the number of products in the event.

Note: mParticle will not attempt to forward eCommerce Events to Amplitude which contain no Products.

The eCommerce events resulting from the expansion that may be forwarded to Amplitude are:

• Transaction level events (e.g. eCommerce - Purchase)
• Item level events (e.g. eCommerce - Purchase - Item)
• Revenue events (e.g. [Amplitude] Revenue)

Transaction Event

• One Transaction Event is forwarded to Amplitude for every valid eCommerce event provided.
• Contains a summary of the transaction, including a JSON array of the products sent in the initial eCommerce event.

Item Events

• One Item Event is forwarded to Amplitude for every product inside the provided eCommerce event.
• Each Item event contains information about one of the products in the provided eCommerce event.

Revenue Event

• One Revenue Event is forwarded to Amplitude for every valid Purchase or Refund eCommerce event provided. Otherwise none is sent.
• The name of the Revenue Event is set by Amplitude, and contains revenue information about the Purchase or Refund event.

eCommerce Event Naming

Each valid eCommerce event sent to mParticle will result in a transaction level event being sent to Amplitude. This event contains a summary of the transaction, including a JSON array of the products sent in the initial eCommerce event.

The name given to the Transaction and Item Level Events is determined from the Product Action provided on the eCommerce Event sent to mParticle.

Event Product Action	Transaction Level Event Name	Item Level Event Names	Revenue Event Name
add_to_cart	eCommerce - AddToCart	eCommerce - AddToCart - Item	N/A
remove_from_cart	eCommerce - RemoveFromCart	eCommerce - RemoveFromCart - Item	N/A
checkout	eCommerce - Checkout	eCommerce - Checkout - Item	N/A
checkout_option	eCommerce - CheckoutOption	eCommerce - CheckoutOption - Item	N/A
click	eCommerce - Click	eCommerce - Click - Item	N/A
view_detail	eCommerce - ViewDetail	eCommerce - ViewDetail - Item	N/A
purchase	eCommerce - Purchase	eCommerce - Purchase - Item	[Amplitude] Revenue
refund	eCommerce - Refund	eCommerce - Refund - Item	[Amplitude] Revenue
add_to_wishlist	eCommerce - AddToWishlist	eCommerce - AddToWishlist - Item	N/A
remove_from_wish_list	eCommerce - RemoveFromWishlist	eCommerce - RemoveFromWishlist - Item	N/A

Custom Event Forwarding

Custom events logged via mParticle’s logEvent SDK method and their attributes will be forwarded to Amplitude, with the event name passed to logEvent as the Amplitude Event Type. An event name must be specified or an error will be returned.

Attribution Custom Event Forwarding

Attribution Custom events will be forwarded to Amplitude prefixed with the attribution provider in the event name. For example, [AppsFlyer] attribution. Event Attributes that are included with the event are forwarded to Amplitude in user_properties, also prefixed with the attribution provider.

Push Registration

mParticle will forward all push registration events to Amplitude with the Amplitude Event Type set to Push Registration. All Field Mappings defined in this documentation will be forwarded too.

Application State Transition Forwarding

If the Send Application State Transitions setting is enabled, Application State Transition events will be forwarded to Amplitude as follows:

Application State Transition	Amplitude event type
initialized, is_first_run = true	Install
initialized, is_upgrade = true	Upgrade
initialized	Application Initialized
exit	Application Exit
background	Application Background
foreground	Application Foreground

Server to Server Web Requests

Only for web requests, mParticle will extract OS and browser info from HTTP user agent. Similar to Amplitude’s SDK behavior, os_name and os_version will be populated with browser info. For that reason, mParticle will send 2 additional Custom User Properties, web_os_name and web_os_version, that will contain OS info. See Amplitude’s doc.

mParticle will also populate device_brand and device_model from the HTTP user agent if the Extract Device Family from User Agent setting is enabled. With this setting enabled, if mParticle cannot determine the device brand or model, it will populate device_brand with the same value as is set for web_os_name. Note, the device values may differ slightly between S2S events and events sent through the Amplitude web kit.

Configuration Settings

Setting Name	Data Type	Default Value	Description
API Key	string	NULL	The Amplitude API Key for each app that you set up.
Amplitude Organization	string	US Organization	The Amplitude datacenter that is configured for your Amplitude organization.
Use Batch API Endpoint	bool	False	If enabled, the Amplitude batch API endpoint will be used. The endpoint has a higher rate limit but may have a slight delay in delivering events. Please note that if the request is replayed, the batch API endpoint will always be used regardless of this configuration value.

Connection Settings

Setting Name	Data Type	Default Value	Platform	Description
User Identification	string	customerId	All	To identify users, choose “Customer ID” to send Customer ID if provided, “Email” to send Email addresses if provided, or “MPID” to send mParticle ID. You can map other IDs by selecting any of the “Other” fields from the User Identification drop-down. These fields can be used to map Other IDs as Customer IDs.
Anonymous ID forwarding	enum	Unselected	All	If enabled, mParticle will send an identifier derived from either Device Application Stamp or a combination of Device Application Stamp and MPID when another device ID does not exist on the batch. This setting is only supported for server-side forwarding. Note, for partner feeds, the value of Device Application Stamp is the same for all MPIDs.
Include Email in User Properties	bool	False	All	If enabled, the email user identity will be forwarded in the Amplitude user_properties.
Allow unset user attributes	bool	True	All	Allow user attributes to be removed in Amplitude using the $unset operation.
Prefix Attribution with Source	bool	True	All	If enabled, the attribution source name will be prefixed for attribution events.
