When calling the v1 Analytics API to get Line Item stats broken by segmentation_type SIMILAR_TO_FOLLOWERS_OF_USER, it only returns one segment group named “Unknown”.
Here’s the query to reproduce the issue using v1 Analytics API:
twurl -H ads-api.twitter.com ‘/1/stats/accounts/:account_id?metric_groups=ENGAGEMENT&placement=ALL_ON_TWITTER&granularity=HOUR&start_time=2016-03-20T00:00:00-07:00Z&end_time=2016-03-23T19:00:00-07:00Z&entity=LINE_ITEM&segmentation_type=SIMILAR_TO_FOLLOWERS_OF_USER&entity_ids=:line_item_id’
Here’s the corresponding query using v0 Analytics API that correctly returns stats broken by twitter handle:
twurl -t -H ads-api.twitter.com ‘/0/stats/accounts/:account_id/line_items/:line_item_id?start_time=2016-03-22T00:00:00-07:00Z&end_time=2016-03-23T19:00:00-07:00Z&segmentation_type=SIMILAR_TO_FOLLOWERS_OF_USER’
