# Amplitude Destination Config Reference

Amplitude is a product analytics destination. RudderStack sends events to Amplitude’s HTTP API from its servers, or loads Amplitude’s own SDKs in device mode on web, Android, iOS, React Native, and Flutter.

In an Amplitude destination spec:

Sample configuration

yaml 
version: rudder/v1
kind: destination
metadata:
  name: amplitude-prod
spec:
  id: amplitude-prod
  display_name: Amplitude Production
  type: am
  definition_version: 1
  enabled: true
  config:
    api_key: "{{ .AMPLITUDE_API_KEY }}"
    api_secret: "{{ .AMPLITUDE_SECRET_KEY }}"
    residency_server: standard

    track_all_pages: false
    track_categorized_pages: true
    track_named_pages: true

    group_type_trait: company_type
    group_value_trait: company_name
    traits_to_set_once:
      - signup_date
    traits_to_increment:
      - login_count

    track_products_once: false
    track_revenue_per_product: true

    sdk_version:
      web: 2
    attribution:
      web: false
    track_session_events:
      web: true
      ios: true
    auto_capture:
      page_views:
        web: false
      web_vitals:
        web: true
    event_upload_threshold:
      web: "30"
      ios: "30"

    connection_mode:
      web: device
      ios: device
      cloud: cloud
    consent_management:
      web:
        - provider: oneTrust
          consents:
            - analytics

The above example loads Amplitude’s SDKs on web and iOS in device mode, with web on SDK version 2 — which is what auto_capture and web track_session_events need. See Web SDK.

Config keys

config accepts only the keys listed below. The shared config key rules cover unknown keys, defaults, and immutability.

Most Amplitude keys affect only one connection mode, or one platform’s SDK. The groups below say which. Rudder CLI accepts every key whatever the mode — a key for the other mode is stored and ignored.

In cloud mode Amplitude accepts alias, group, identify, page, screen, and track. In device mode, web sources send identify, track, page, and group; mobile sources send identify, track, and screen.

Connection

api_key

RequiredSecret

Type: string

Description: API key of your Amplitude project, from the project’s General tab.

Notes:

  • At most 100 characters, and must not contain line breaks.
  • A {{ path || fallback }} template is accepted in place of a literal.

residency_server

Required

Type: string

Description: Amplitude data center RudderStack sends to.

Notes:

  • standard (US) or EU.
  • The dashboard defaults this field to standard. Rudder CLI requires it explicitly.
  • A spec that omits this key fails validation.

api_secret

Secret

Type: string

Description: Secret key of your Amplitude project. RudderStack needs it to delete users, for example for GDPR requests. The dashboard calls it Secret key.

Notes:

  • At most 100 characters, and must not contain line breaks.
  • A {{ path || fallback }} template is accepted in place of a literal.

Page and screen events

track_all_pages, track_categorized_pages, and track_named_pages apply in device mode. On mobile they act on screen events rather than page events. Turning on more than one can send several Amplitude events for a single call. The custom name keys apply in cloud mode.

track_all_pages

Type: boolean

Default value: false

Description: Send every page call to Amplitude as a Loaded a Page event.

Notes:

  • Applies to sources connected in device mode.

track_categorized_pages

Type: boolean

Default value: true

Description: Send an event for each page call that has a category.

Notes:

  • Applies to sources connected in device mode.

track_named_pages

Type: boolean

Default value: true

Description: Send an event for each page call that has a name.

Notes:

  • Applies to sources connected in device mode.

use_user_defined_page_event_name

Type: boolean

Default value: false

Description: Name page events from user_provided_page_event_string instead of the default name.

Notes:

  • Applies to events sent in cloud mode.

user_provided_page_event_string

Type: string

Description: Format for page event names. Each {{ field }} is replaced with that field from the event payload — for example Viewed {{ name }} page.

Notes:

  • Applies when use_user_defined_page_event_name is true. Leave it unset otherwise.
  • At most 200 characters, and must not contain line breaks.
  • {{ field }}-style fields have no leading dot, so Rudder CLI’s variable substitution leaves them alone.

use_user_defined_screen_event_name

Type: boolean

Default value: false

Description: Name screen events from user_provided_screen_event_string instead of the default name.

Notes:

  • Applies to events sent in cloud mode.

user_provided_screen_event_string

Type: string

Description: Format for screen event names, on the same terms as user_provided_page_event_string.

Notes:

  • Applies when use_user_defined_screen_event_name is true. Leave it unset otherwise.
  • At most 200 characters, and must not contain line breaks.

Identify and group traits

The trait lists take arrays of trait names, each at most 100 characters or a {{ path || fallback }} template.

group_type_trait

Type: string

Description: Trait whose value becomes the Amplitude group_type in group calls — for example a trait holding industry.

Notes:

  • At most 100 characters, or a template.

group_value_trait

Type: string

Description: Trait whose value becomes the Amplitude group_value in group calls — for example retail for the industry type.

Notes:

  • At most 100 characters, or a template.

traits_to_increment

Type: array of strings

Description: identify traits Amplitude increments by their numeric value instead of overwriting.

traits_to_set_once

Type: array of strings

Description: identify traits Amplitude sets once and never overwrites.

traits_to_append

Type: array of strings

Description: identify traits whose values are appended to a list user property.

Notes:

  • Applies to cloud mode and to mobile sources in device mode — not to web device mode.

traits_to_prepend

Type: array of strings

Description: identify traits whose values are prepended to a list user property.

Notes:

  • Applies to cloud mode and to mobile sources in device mode — not to web device mode.

enable_enhanced_user_operations

Type: boolean

Default value: false

Description: Enable Amplitude’s enhanced user property operations.

Notes:

  • Applies to cloud mode.
  • The dashboard shows this setting only to workspaces with the feature turned on.

Ecommerce

track_products_once

Type: boolean

Default value: false

Description: Send an event carrying a products array as one event, with the products as properties, instead of one event per product.

track_revenue_per_product

Type: boolean

Default value: false

Description: Track each product’s revenue individually. When false, the event carries the aggregate revenue of all products.

Web SDK

These keys configure Amplitude’s web SDK, so they apply only when connection_mode.web is device. Each object is keyed by web.

Several of these apply only to one web SDK version, set by sdk_version.web. auto_capture and track_session_events.web need version 2; track_new_campaigns needs version 1. A key for the other version is accepted and has no effect.

sdk_version

Type: object

Description: Version of Amplitude’s web SDK RudderStack loads. Review the behavior changes in version 2 before switching an existing destination.

Notes:

  • web — 1 or 2, written as a number, not a string.
  • Rudder CLI fills in 2 only when the sdk_version block is present. Omit the block and no version is sent, so write it out.
yaml 
sdk_version:
  web: 2

proxy_server_url

Type: object

Description: Domain proxy that relays the SDK’s requests to Amplitude.

Notes:

  • web — string. Must not start with http:// and must not contain .ngrok.io. A template is accepted.
  • The proxy must use HTTPS. Otherwise the proxy is ignored and data goes to Amplitude directly.

version_name

Type: string

Description: Version name sent to Amplitude with each event, for more detailed analysis.

Notes:

  • Applies when connection_mode.web is device.
  • At most 100 characters, or a template.

prefer_anonymous_id_for_device_id

Type: object

Description: Use the RudderStack anonymous ID as Amplitude’s device ID instead of the SDK’s own.

Notes:

  • web — boolean.

attribution

Type: object

Description: Disables attribution tracking. true turns attribution off: GCLID, UTM parameters, and referrer aren’t tracked. The dashboard calls this Disable Attribution.

Notes:

  • web — boolean.
Despite its name, attribution: {web: true} switches attribution off. To keep attribution, leave it false or unset.

track_new_campaigns

Type: object

Description: Save the referrer, URL parameters, and GCLID only once per session, ignoring new values that arrive later in the session. The dashboard calls this Save Referrer, URL Params, GCLID only once per session — it doesn’t track new campaigns, whatever the name suggests.

Notes:

  • Applies when sdk_version.web is 1. Leave it unset otherwise.
  • web — boolean. The dashboard defaults it to true; Rudder CLI doesn’t fill it in.

auto_capture

Type: object

Description: Interactions Amplitude’s web SDK captures on its own. Each setting is an object keyed by web, with a boolean value that defaults to false when the setting is present.

Notes:

  • Applies when sdk_version.web is 2. Leave it unset otherwise.
  • page_views — emit [Amplitude] Page Viewed on navigation, in addition to RudderStack’s page calls. Leave off if you already send page calls on navigation, or page views are counted twice.
  • page_url_enrichment — attach the current page URL to every event.
  • web_vitals — capture Core Web Vitals (LCP, FCP, INP, CLS, TTFB).
  • file_downloads — capture clicks on download links.
  • frustration_interactions — capture rage clicks, dead clicks, and error clicks.
  • network_tracking — capture failed network requests.
  • element_interactions — capture clicks and changes on every element. High volume, and can capture user-entered text.
  • form_interactions — capture form submissions and field changes, including field values that may be PII.
yaml 
auto_capture:
  web_vitals:
    web: true
  file_downloads:
    web: true

Mobile SDK

These keys configure Amplitude’s mobile SDKs, so they apply only to mobile sources connected in device mode. Each is an object keyed by the source types listed, with a boolean value.

map_device_brand

Type: boolean

Default value: false

Description: Send the device brand to Amplitude.

Notes:

  • A plain boolean, not keyed by source type. Applies to android, ios, react_native, and flutter in device mode.

enable_location_listening

Type: object

Description: Capture location for users who’ve granted the app location permission.

Notes:

  • android, react_native, flutter — booleans. The dashboard defaults them to true; Rudder CLI doesn’t fill them in.

use_advertising_id_for_device_id

Type: object

Description: Send the Android Advertising ID as Amplitude’s device ID.

Notes:

  • android, react_native, flutter — booleans.

use_idfa_as_device_id

Type: object

Description: Send the iOS IDFA as Amplitude’s device ID.

Notes:

  • ios, react_native, flutter — booleans.

Batching and sessions

These keys apply to both web and mobile SDKs, so they take effect for any source connected in device mode. Each is keyed by source type.

event_upload_period_millis

Type: object

Description: Time, in milliseconds, between the SDK’s batch uploads.

Notes:

  • web, android, ios, react_native, flutter — digits only, written as a string: "1000", not 1000. At most 100 characters, or a template.
  • The dashboard defaults it to "1000"; Rudder CLI doesn’t fill it in.
yaml 
event_upload_period_millis:
  web: "1000"
  android: "5000"

event_upload_threshold

Type: object

Description: Minimum number of events the SDK collects before uploading a batch.

Notes:

  • web, android, ios, react_native, flutter — digits only, written as a string: "30", not 30. At most 100 characters, or a template.
  • The dashboard defaults it to "30"; Rudder CLI doesn’t fill it in.

track_session_events

Type: object

Description: Send session start and end events.

Notes:

  • android, ios, react_native, flutter — booleans.
  • web — boolean, default false when the block is present. Applies only when sdk_version.web is 2.

Internal keys

The eight keys below are older Amplitude web SDK settings — the keys above are what configure today’s integration. Rudder CLI accepts them so that a destination already carrying these values keeps them; without them in the spec, an update would drop whatever is stored. Leave them out of a new destination, and keep whatever rudder-cli import brings back.

Each is an object keyed by web, with a boolean value.

batch_events

Internal

Type: object

Description: Batches events in the browser before uploading them. event_upload_period_millis and event_upload_threshold are the keys the dashboard exposes for batching.

device_id_from_url_param

Internal

Type: object

Description: Sets the device ID from the amp_device_id URL parameter.

force_https

Internal

Type: object

Description: Always uploads over HTTPS, rather than following the embedding page’s protocol.

track_gclid

Internal

Type: object

Description: Captures the gclid URL parameter alongside the user’s initial_gclid. Attribution as a whole is controlled by attribution.

track_referrer

Internal

Type: object

Description: Captures referrer and referring_domain for each session, alongside the user’s initial values.

track_utm_properties

Internal

Type: object

Description: Parses UTM parameters from the query string or _utmz cookie and sends them as user properties.

save_params_referrer_once_per_session

Internal

Type: object

Description: Captures GCLID, referrer, and UTM parameters once per session. On web SDK version 1, track_new_campaigns is the key the dashboard exposes for this.

unset_params_referrer_on_new_session

Internal

Type: object

Description: Resets referrer and UTM properties to null at the start of each session, instead of carrying the previous values forward.

Event filtering

Client-side event filtering applies only to sources connected in device mode — the dashboard shows these controls only then, and the SDK is what applies the filter. Rudder CLI accepts the block in any mode, but it has no effect on cloud-mode events.

event_filtering

Type: object

Description: Restricts which track events the SDK passes to Amplitude, by event name.

Notes:

  • whitelist — array of event names to allow; every other track event is dropped.
  • blacklist — array of event names to drop; every other track event is allowed.
  • The two are mutually exclusive, and Rudder CLI enforces it — setting both fails validation.
  • Each name is at most 100 characters, or a {{ path || fallback }} template.

Per-source keys

Both keys are objects keyed by the local source type — the tokens listed under Source types. A key naming a source type this destination doesn’t support fails validation.

connection_mode

Type: object

Description: Maps each source type you connect to the mode its events reach Amplitude in, using the modes in Source types.

Notes:

  • An entry is required for each source type you connect — see Connect a source.
  • A mode the source type doesn’t support on this destination fails validation — for example device for ios_swift.
yaml 
connection_mode:
  web: device
  ios: device
  android_kotlin: cloud

Source types

Amplitude accepts events from these source types in the mentioned connection modes:

Source type Connection mode
android cloud, device
android_kotlin cloud
ios cloud, device
ios_swift cloud
web cloud, device
unity cloud
cloud cloud
react_native cloud, device
flutter cloud, device
cordova cloud

web, android, ios, react_native, and flutter offer device mode. The Kotlin and Swift SDKs — android_kotlin and ios_swift — are cloud only. See Amplitude device mode.

The dashboard additionally offers Amplitude to AMP, Shopify, and Reverse ETL sources. Rudder CLI doesn’t manage those connections, so amp, shopify, and warehouse are invalid here.

Connect a source

An event stream connection to this destination is checked against two rules at validate time.

The source’s type must be supported. A source’s type resolves to one of the tokens above before the check — a JavaScript source resolves to web, and webhook and server-side SDK sources resolve to cloud. An unsupported type reports:

destination 'amplitude-prod' (type 'am') does not support source 'my-source':
source type 'amp' is not among supported source types: android, android_kotlin, ...

The destination config must carry a connection_mode entry for that source type. This lives on the destination spec, not on the connection spec. Without it:

destination 'amplitude-prod' config has no 'connection_mode' entry for source type 'web'

Amplitude needs no additional config keys to connect a source of any type, in any mode.

Secrets

api_key and api_secret are the secret keys. Write each as a {{ .VAR }} reference and supply the value at apply time:

yaml 
config:
  api_key: "{{ .AMPLITUDE_API_KEY }}"
  api_secret: "{{ .AMPLITUDE_SECRET_KEY }}"
bash 
export RUDDER_AMPLITUDE_API_KEY="..."
export RUDDER_AMPLITUDE_SECRET_KEY="..."
rudder-cli apply

# or
rudder-cli apply --var-file secrets.vars.yaml
