## Migrating from API V1 to API V2

### Background

Analytics API V1 returns data from Google Analytics V3, also known as Universal
Analytics (UA).

Google is retiring UA and is encouraging users to move to their new
version Google Analytics V4 (GA4) in 2024.

Analytics API V2 returns data from GA4.

### Migration details

#### Requests

The Analytics API endpoints are the same between V1 and V2, the only difference
for API requests is the API version string.

#### Responses

Response data is slightly different in Analytics API V2. This change is due to
the data provided by Google Analytics. Some data fields were retired in GA4, and
some other useful data fields were added. The changes follow:

##### Deprecated fields

- browser_version
- has_social_referral
- exits
- exit_page

##### New fields

###### bounce_rate

The percentage of sessions that were not engaged. GA4 defines engaged as a
session that lasts longer than 10 seconds or has multiple pageviews.

###### file_name

The page path of a downloaded file.

###### language_code

The ISO639 language setting of the user's device. e.g. 'en-us'

###### session_default_channel_group

An enum which describes the session. Possible values:

'Direct', 'Organic Search', 'Paid Social', 'Organic Social', 'Email',
'Affiliates', 'Referral', 'Paid Search', 'Video', and 'Display'
