Business Profile Performance: values are differente than GBP App

Question

I have a gap in values between the one returned by Google Business Profile Performance API and the one in Google Business Profile application.

For example, on 14th July 2022, Google Business Profile Performance API give me a value to 28 for the BUSINESS_DIRECTION_REQUESTS metric.

The request parameters:

{
  "dailyMetric": "BUSINESS_DIRECTION_REQUESTS",
  "dailyRange.startDate.day": 20,
  "dailyRange.startDate.month": 7,
  "dailyRange.startDate.year": 2021,
  "dailyRange.endDate.day": 17,
  "dailyRange.endDate.month": 7,
  "dailyRange.endDate.year": 2022,
  "name": "locations/10[...]19"
}

The response on 14th July:

{
  "date": {
    "year": 2022,
    "month": 7,
    "day": 14
  },
  "value": "28"
}

For the same day, on Google Business Profile application, the graph of customer actions give me 40 itinirary requests:

How to explain this gap between values ?

Answer 1

I had the same issue where BUSINESS_DIRECTION_REQUESTS were much lower than their old, supposedly equivalent metric actions_driving_directions. I contacted Google Profile and this was their answer:

“Going forward with the new Performance API multiple impressions by a unique user within a single day are counted as a single impression.”
