使用delivery_estimate通过Facebook Graph API获取估计的每日结果

Question

我尝试生成一个HTTP条目，但它只向我显示estimate_dau和estimate_mau，但没有向我显示每日结果曲线。

我希望看到更多这样的东西：

{  "data": [
{
"bid_estimate": {
"min_bid": 25,
"median_bid": 39,
"max_bid": 62
},
"daily_outcomes_curve": [
{
"spend": 0,
"reach": 0,
"impressions": 0,
"actions": 0
},
{
"spend": 265,
"reach": 8243.6443831081,
"impressions": 10350.320895139,
"actions": 156.50895237165
},
{
"spend": 526,
"reach": 18251.053723186,
"impressions": 22749.898172632,
"actions": 240.93947618433
},
{
"spend": 765,
"reach": 28407.177135996,
"impressions": 33619.733342562,
"actions": 346.99329322783
},

这是我提出的要求：

https://graph.facebook.com/v7.0/act_{ad account id}/delivery_estimate?targeting_spec=%7B%22geo_locations%22%3A%7B%22countries%22%3A%5B%22PH%22%5D%7D%2C%22age_min%22%3A21%2C%22age_max%22%3A21%2C%22publisher_platforms%22%3A%5B%22facebook%22%5D%2C%22facebook_positions%22%3A%5B%22feed%22%5D%2C%22device_platforms%22%3A%5B%22mobile%22%2C%22desktop%22%5D%2C%22interests%22%3A%5B%7B%22id%22%3A%226002839660079%22%2C%22name%22%3A%22Cosmetics%22%2C%7D%5D%7D&optimization_goal=REACH&access_token={access token}

但这是我得到的唯一回应：

{   "data": [
{
"daily_outcomes_curve": [
{
"spend": 0,
"reach": 0,
"impressions": 0,
"actions": 0
}
],
"estimate_dau": 1316892,
"estimate_mau": 1800000,
"estimate_ready": true
}

Answer 1

将同一 API 与广告集 ID 而非广告帐户 ID 配合使用。graph.facebook.com/v7.0/adset_id}/delivery_estimate?

Answer 2

只有当Facebook能够提供高置信度预测时，daily_outcomes_curve字段才会有数据。当Facebook没有高置信度预测时，它将返回一个1点的数组，所有0。
