About Tailored Audience. I'd like to confirm if what I expect is right

[saku_yoshir]

Hello

I am trying to make a Tailored Audience which contains users’ idfas using Twitter Ads API.

I refer to this document.
https://developer.twitter.com/en/docs/ads/audiences/guides/ta-realtime-integration-guide

My Tailored Audiences should be updated everyday.

I expect the list of idfas in the Tailored Audience to be different targetable idfas compared to the previous day,so they should be replaced with another group of idfas everyday.

I send the idfas to Twitter at around 5 AM everyday.

If I sent them to Twitter on 31 Octorber,each idfas’ settings would be like below.

 {
      "operation_type":"Update",
      "params":{
         "membership_type": "LIST_MEMBERSHIP",
         "advertiser_account_id":<my_ad_account_id>,
         "user_identifier":<user_idfa>,
         "user_identifier_type":"DEVICE_ID",
         "audience_names":<audience_name>,
         "effective_at":"2017-10-31T00:00:00Z",
         "expires_at":"2017-10-31T23:50:00Z"
      }
   }

I’d like the idfas to expire today and to be replaced by another group of idfas tomorrow.

I’m not sure if what I am expecting is right or not.

Thanks
