Hi Terrance, speaking of Windows, here is a handy way to get checkin data using PowerShell. This uses the API endpoint: Endpoint: /v4/user/checkins/USERNAME
Invoke-RestMethod -Method GET -Uri "https://api.untappd.com/v4/user/checkins/myuserid?access_token=myuntappdaccesstoken" | ConvertTo-Json -Depth 20 | Tee-Object -FilePath "myuserid_User_checkins.json"
That's does not enumerate all of the checkin data but at least gets the first 25 if looking for a quick way to grab sample JSON for an API when working on an app.
It would be fun if you were able to explore the Untappd private APIs used by the Untappd app similar to what you did opening up the Remote app for the BMW i3. There are some much more powerful searches under the covers!
