Not sure who to ask about this — with the migration from API v0 to v1, is the
/v0/stats/accounts/:account_id/reach/campaigns endpoint being kept alive?
The new v1 API does not include an endpoint for campaign reach stats. We need to know if Twitter will keep alive the old v0 campaign reach stats endpoint, even though all the other old v0 endpoints are being turned off. The implication is that if Twitter doesn’t make an exception for the old v0 campaign reach stats endpoint, we will have no way of collecting those stats when v0 is turned off.
The endpoint in question is referenced here: https://dev.twitter.com/ads/reference/get/stats/accounts/%3Aaccount_id/reach/campaigns
