This is an app that acts as an agent selling a party service.
It needs a working API interface, e.g. this here should work:
PS C:\WINDOWS\System32> $body = @{
>> type = "order"
>> customer = "Thorsten"
>> address = "Baumstrasse 5"
>> item = "Caviar"
>> quantity = "500kg"
>> schedule = "2026-07-18 18:07"
>> recurrence = "none"
>> correlation_id = "none"
>> } | ConvertTo-Json -Compress
PS C:\WINDOWS\System32> Invoke-RestMethod -Uri "https://script.google.com/macros/s/AKfycbxksLxAM3iSJHYPTZ7eCi4fm8Fte3CPKnH3eo7FaTy_BSpm3gzwyjyRGzcax1xEV04-/exec" -Method Post -ContentType "application/json" -Body $body -MaximumRedirection 5
