API - Get count of subscribers in List or Segment

Hi,

I would very much also like this feature to be added to the API for segments for our BI setup.

any update on this coming?

Hi @mkren47 @larindom @heroarts.corfin @1stevengrant @viddepidde,

Quick update for everyone - the V3 API will give you the ability to pull the subscription status for all profiles in a given list or segment. We’re looking at a timeframe of Q4 22’ to Q1 23’ for this particular feature. 

Thanks for being community members and making the community a place to share ideas and inspiration.

We also need list size for our use case, I think a simple count attribute on the List object would suffice:

{
  "type": "list",
  "id": "Y6nRLr",
  "attributes": {
    "count": 12627,
    "name": "Newsletter"
  }
}

That should open the door for some powerful filtering too!

Hi @david_hbm!

There’s no update at this time, but I’ll tag you and notify the thread as soon there is!

Best,

Brian

Still waiting a update, adding a “total” or “count” in the response is a quick solution that work for everyone

Need update on this. When will this feature will be available?

I don’t see this at all.  I simply do not get a profile_count.  I made sure I’m using API release 2023-08-15 but all I see is:
 

Listinfo (2023-08-15): Array
(
    [data] => Array
        (
            [type] => list
            [id] => YzT7bf
            [attributes] => Array
                (
                    [name] => tx store list
                    [created] => 2022-10-21T21:37:16+00:00
                    [updated] => 2022-10-21T21:37:16+00:00
                )

            [relationships] => Array

No profile_count at all.  What might I be missing?  I’m calling https://a.klaviyo.com/api/lists/YzT7bf/

And this profile_count should be added to the https://a.klaviyo.com/api/lists/ call too.  I get all my lists, but I still have to loop through them all to get a profile_count.

Hi @kenw232 and @bproulx!

If you’re not seeing the profile count it’s because you have to elect to include the additional-fields[list] Query Param for profile count when making the call. See the example here in the developer portal:

This will adjust the URL to look like this:

https://a.klaviyo.com/api/lists/YzT7bf/?additional-fields[list]=profile_count

Best,

Brian

Can I use this ?additional-fields[list]=profile_count on all the /lists/ listing too?  Or do this only work on a single /lists/Yzt7bf/ type of thing?

This is bad.  Our customer allows us to view their lists/segments for our web app.  We need to show the profile count for each.  They have about 100 lists.

Rate limits when using the additional-fields[segment]=profile_count parameter in your API request:
Burst: 1/s
Steady: 15/m

So under the old API I could hit https://a.klaviyo.com/api/v1/lists... to get all the lists and a person_count was included.  Great.  It only took like 1 second to get 100 lists and their counts.

Now under the new V3 API I must separately call each /lists/xyzabc to get its profile_count.  But the rate limit forces me to do this as low as 15 hits a minute.. so to list 100 lists + their counts now takes close to two minutes.  The user just sits there waiting. 

Absolutely ridiculous and makes our solution useless.  Where it was great before.  Why are you making things worse?
