Google Analytics 4 Cloud Mode Integration
Send events to Google Analytics 4 using RudderStack cloud mode.
RudderStack lets you send your event data to Google Analytics 4 via cloud mode by leveraging the Google Analytics 4 Measurement Protocol.
Google Analytics 4 does not officially support a complete server-to-server integration. RudderStack utilizes the GA4 Measurement Protocol API for cloud mode integration, which does not currently allow ingestion of UTM parameters for attribution reporting. This may significantly limit your ability to use certain GA4 reporting features. Refer to the Google’s documentation for more information on these limitations.
For capturing a fuller, more robust set of attribution data while using Measurement Protocol, RudderStack suggests referencing and setting up a hybrid mode connection.
Find the open source transformer code for this destination in the GitHub repository.
Tagging methods
RudderStack supports both the gtag
and firebase
ways for tagging in websites in cloud mode. However, note that:
- If you use
gtag
, passing the client_id
parameter is mandatory. - If you use
firebase
, passing the app_instance_id
parameter is mandatory.
Refer to the Google Analytics 4 Measurement Protocol guide for more information.
The mappings for the above-mentioned mandatory parameters are listed in the following table:
Mapping client_id
RudderStack maps client_id
from the following fields in the same priority order as listed below:
- From
externalID
: ga4ClientId
- From
anonymousId
- From
rudderId
externalId
You can use externalID
to send a custom client_id
that is external to RudderStack.
There are certain scenarios where you may want to send a custom client_id
. For example, if you maintain a user with a certain identifier, then you may prefer to pass it as the custom client_id
as a part of externalId
:
rudderanalytics.identify(
"1hKOmRA4GRlm", {
firstName: "Alex",
city: "New Orleans",
country: "Louisiana",
phone: "+1-202-555-0146",
email: "alex@example.com",
} {
externalId: [{
id: "4718026.1683606287",
type: "ga4ClientId",
}, ],
}
);
Supported mappings
The following table lists the mappings for the gtag
and firebase
parameters:
Parameters | Mapping | Description |
---|
user_id | userId traits.userId traits.id context.traits.userId context.traits.id | Unique identifier for a user which helps Google Analytics 4 know if two devices/browsers belong to the same user. |
timestamp_micros | originalTimestamp timestamp | Timestamp in ISO 8601 format. |
non_personalized_ads | context.device.adTrackingEnabled | Indicates whether the events should be used for personalized ads. If context.device.adTrackingEnabled is set as true , non_personalised_ads will be set to false . |
Google Analytics 4 Measurement Protocol only supports timestamps 72 hours into the past and 15 minutes into the future. RudderStack discards any event with a timestamp out of this range.
Track
The track
call lets you capture user events along with the properties associated with them.
You can use a track
call to send any event to Google Analytics 4. However, RudderStack recommends using the page
call to record page-related information for your website specifically.
You can send all the events mentioned in GA4 documentation as track
events.
A sample track
call using gtag
is shown below:
rudderanalytics.track('Product List Viewed', {
list_id: "related_products",
category: "Related_products",
products: [{
product_id: "507f1f77bcf86cd799439011",

item_category3: "Shirts",
item_category4: "Crew",
item_category5: "Short sleeve",
item_list_id: "related_products",
item_list_name: "Related Products",
location_id: "L_12345"
}]
}, {
externalId: [{
type: "ga4ClientId",
id: "client_id"
}],
});
A sample track
call using firebase
is shown below:
rudderanalytics.track('Product List Viewed', {
list_id: "related_products",

item_category5: "Short sleeve",
item_list_id: "related_products",
item_list_name: "Related Products",
location_id: "L_12345"
}]
}, {
externalId: [{
type: "ga4AppInstanceId",
id: "f0dd99b6f979fb551ce583373900f937"
}],
});

traits.engagementTimeMsec properties.engagementTimeMsec context.traits.engagementTimeMsec traits.engagement_time_msec properties.engagement_time_msec context.traits.engagement_time_msec | engagement_time_msec | 1 |
Page
The page
call lets you record your website’s page views with any additional relevant information about the viewed page.
RudderStack maps the page
call to a page_view
event by default, and passes it to Google Analytics 4 as a custom event.
As mentioned in the track
section, the RudderStack cloud mode supports both the gtag
and firebase
methods for tagging in websites.
A sample page
call using gtag
is shown below:
A sample page
call using firebase
is shown below:
rudderanalytics.page({}, {
externalId: [{
type: "ga4AppInstanceId",
id: "f0dd99b6f979fb551ce583373900f937"
}],
});
Supported mappings
The following table lists the property mappings between RudderStack and Google Analytics 4:
RudderStack property | Google Analytics 4 property |
---|
context.page.referrer | page_referrer |
context.page.title | page_title |
context.page.url | page_location |
Group
The group
call lets you link an identified user with a group such as a company, organization, or an account, and record any traits associated with that group, for example, company name, number of employees, etc.
RudderStack maps the group
call to the join_group
event by default.
A sample group
call using gtag
is shown below:
rudderanalytics.group("1hKOmRA4", {
"custom1": 1234,
"custom2": "custom2"
});
A sample group
call using firebase
is shown below:
rudderanalytics.group("1hKOmRA4", {
"custom1": 1234,
"custom2": "custom2"
}, {
externalId: [{
type: "ga4AppInstanceId",
id: "f0dd99b6f979fb551ce583373900f937"
}],
});

properties.campaign.source | source |
context.campaign.medium
properties.campaign.medium | medium |
context.campaign.term
properties.campaign.term | term |
context.campaign.content
properties.campaign.content | content |
You can pass the custom user properties to any of the events by passing them as
properties.user_properties
or
context.traits
. Refer to the
Google Analytics 4 documentation for more information.
Custom events
You can use custom events to collect additional information that Google Analytics 4 does not collect automatically.
Follow the below rules while choosing a name for the custom events and parameters:
- Event names are case-sensitive. For example,
my_event
and My_Event
are two distinct events. - Event names must start with a letter. Only letters, numbers, and underscores are permitted. Do not use spaces.
- Do not use reserved prefixes and event names. The list of such prefixes is mentioned below:
- _ (underscore)
- firebase_
- ga_
- google_
- gtag.
- Do not use spaces in event parameter names.
Custom dimensions and metrics
Before sending events to Google Analytics 4, you must create custom dimensions and metrics in your GA4 dashboard and link them to the event properties/parameters.
You can select a parameter from the list of already collected properties or specify the parameter you plan to collect in the future. RudderStack supports sending user properties via properties.user_properties
and context.traits
.
Note that:
- Custom dimensions can be either event-scoped or user-scoped. However, custom metrics must be event-scoped.
- Each user property should either be of a number, string, or Boolean data type. This is because GA4 accepts only flat key-value pairs as user properties.
- RudderStack drops any user property that is either an object or an array.
Tracking active users and sessions
As Google Analytics 4 only reports the users who engage with your website for a non-zero time, RudderStack sets the engagement_time_msec
parameter to 1, by default. To track engagement time in your events, you can set the engagement_time_msec
field to a different value.
RudderStack maps the following properties to GA4’s engagement_time_msec
property:
RudderStack properties | Google Analytics 4 property |
---|
traits.engagementTimeMsec
context.traits.engagementTimeMsec
traits.engagement_time_msec
context.traits.engagement_time_msec | engagement_time_msec |
You can use the Google Analytics 4 session_id
parameter to identify the session associated with a particular event.
To know more about sessions in Google Analytics 4, see Google Analytics 4 help article.
RudderStack maps the following session properties for the group
call:
RudderStack properties | Google Analytics 4 property |
---|
traits.sessionId
context.traits.sessionId
traits.session_id
context.traits.session_id
context.sessionId | session_id |
RudderStack maps the following session properties for the track
and page
calls:
RudderStack properties | Google Analytics 4 property |
---|
properties.sessionId
properties.session_id
context.sessionId | session_id |
RudderStack automatically collects
engagement_time_msec
and
session_id
when sending events via
device mode. However, they must be manually passed while sending events via cloud mode.
Server-side session tracking supports only a subset of user dimensions. Google’s Measurement Protocol API does not support the reserved fields like location, demographics,
predefined user dimensions, and device-specific information.
See Google Analytics 4 documentation for more information on the optional reporting parameters.
View events in GA4
To verify if your events are sent to GA4 successfully, go to Reports > Realtime in your Google Analytics dashboard or check Debug View (only available in device mode). For more information, see GA4 documentation for more information.
It can take up to 24 hours for the data to be processed in GA4 and appear in the other reports.
Events not showing in GA4
If your events do not show up in GA4’s Realtime view, there could be issues with your implementation. See GA4 documentation for more information on verifying your implementation or checking the realtime view.
You can also see the GA4 Troubleshooting guide for steps on identifying and fixing any possible implementation issues.
Also, make sure you are not using a reserved name for your events. This is a common reason for events not showing up in GA4. See FAQ for more information on reserved event names.
Not all types of data flow through to GA4’s Realtime dashboard. For example, the Measurement Protocol does not support geolocation data and it does not show up in the Realtime dashboard (except for page
calls sent via hybrid mode).
FAQ
What does the (not set) value mean in reports?
If you see (not set) value in your reports, see GA4 documentation to diagnose the cause first.
RudderStack utilizes the GA4 Measurement Protocol API for cloud mode integration. It does not support ingestion of UTM parameters for attribution reporting currently.
Some other probable reasons could be:
Reserved event, parameter, and user property names in Google Analytics 4
Google Analytics 4 has some reserved event, parameter, and user property names that cannot be used. If passed, they are dropped silently. See Measurement Protocol (Google Analytics 4) for a complete list of reserved names. Also, note that Google does not accept any event/user property names that include spaces or fields that include null values.
DebugView
DebugView is only supported in the device mode and is enabled automatically when you set up a device mode GA4 connection. For cloud mode connections, RudderStack sends the events to the validation server and they do not show up in reports.
Validating events
The Google Analytics Measurement Protocol for Google Analytics 4 does not return HTTP
error codes, even if an event is malformed or missing required parameters. To ensure your events are valid, you should test them against the Measurement Protocol Validation Server before deploying them to production. See Validating events for more information.
How do I obtain app_instance_id
?
You can retrieve app_instance_id
through the Firebase SDK depending on the platform where the SDK is installed:
See GA4 documentation for more information.
