I am building a server side application that needs to report data to GA via Measurement Protocol.

I want to fill the languages that the user have, from the documentation: https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters#ul

It seems the right parameter is called ul and an example value is en-us.

My questions are:

  1. which kind of langague identifier it accepts? the documentation isn't clear on that. My guess is that following the "en-us" example suggests it is based on Accept-Language header so probably ISO-639-1 +ISO-3166)

  2. It only has space for 20 bytes, so does it means you can't send multiple langagues?

  3. Does the reporting show multiple languages?

  • In a web setting User Language is actually the set browser language, of which there is only one at a time. Just out of curiosity, what would be the use case for multiple languages ? I doubt GA will care what you enter as value, so in theory you could send a list, but you will not be able do do a breakdown by list items. – Eike Pierstorff Jun 09 '16 at 13:09

  1. If you goto Google Analytics Dashboard -> Audience -> Geo -> Language and hover over the help icon next to language column you get this popup -

enter image description here

It apparently uses ISO 639 language codes.

  1. Only one language can be sent per hit. It is not a multi value property.

  2. (2) above makes it obvious what reports can show

  3. In the documentation (as of aug '18), the following is shown:

Optional. Specifies the language. 

Parameter Value | Type | Default Value | Max Length | Supported Hit Types 
ul                text   None            20 Bytes     all

Example value: en-us Example usage: ul=en-us
