Customer List not updated when using "uploadUserData" method

[Eouzan Guillaume]

Hello,

I am using the uploadUserData method to keep my customer lists updated every 10 minutes. My scripts have been running succesfully for over 2 months now, giving me what seems to be a valid response to each request. However, when I look at my user lists in the Google Ads UI, the number of users is not moving at all.

I'm aware the uploadUserData method does not show new "imports" in the UI (contrary to offlineUserDataJobs), however I think it should still increase the number of users in the list, especially since I've been sending hundreds of new users since two months. 

You will find in attachment an example the request and the response.

I'd like to know if you see anything wrong with my requests or if that behavior is normal?

As a side note, this happens on several accounts using the same requests. However, with one other account that uses a Zapier connection instead, I can clearly see the list growing in volume, even though it seems to me that Zapier uses that same method (since no "importations" are registered either in the UI), which leads me to believe I am doing something wrong.

PS: I can confirm that the customer IDs and list IDs used are valid. 

Best,
