I have a tailored audience (id: sax5) with an audience_size of ~4000. I’m trying to make a reach_estimate call with this tailored audience:
https://ads-api.twitter.com/0/accounts/2aio14/reach_estimate?user_id=138599464&placement_type=PROMOTED_TWEETS_FOR_TIMELINES&tailored_audiences=sax5
and get the following response:
{“data_type”:“reach_estimate”,“data”:{“count”:0,“infinite_bid_count”:0},“request”:{“params”:{“placement_type”:“PROMOTED_TWEETS_FOR_TIMELINES”,“user_id”:“138599464”,“tailored_audiences”:[“sax5”],“account_id”:“2aio14”}}}
The response for this audience is:
{“data_type”:“tailored_audiences”,“data”:{“targetable”:true,“name”:“ONEHOPE Wine Connections for Mailchimp”,“targetable_types”:[“CRM”,“EXCLUDED_CRM”],“audience_type”:“CRM”,“id”:“sax5”,“reasons_not_targetable”:[],“list_type”:“EMAIL”,“created_at”:“2015-05-20T03:54:07Z”,“updated_at”:“2015-05-20T20:28:17Z”,“partner_source”:“OTHER”,“deleted”:false,“audience_size”:“4033”},“request”:{“params”:{“tailored_audience_id”:“sax5”,“account_id”:“2aio14”}}}
So there are clearly users in this tailored audience. Is there something I’m missing about the reach estimate?
