The API has started returning duplicate leads.

We've been making queries like this daily since 2018-06-28:

GET /api2/leads/?apiKey=$apiKey&limit=100&modified_date=8%2F10%2F2018+-+8%2F11%2F2018&rowsort=5&rowdir=ASC

$ http get 'https://www.inflatableoffice.com/api2/leads/' \
  apiKey=="$apiKey" \
  limit=='1000' \
  modified_date=='8/15/2018 - 8/16/2018' \
  rowsort=='5' \
  rowdir=='ASC' \
| jq --raw-output '.items[] | .id' \
| sort | uniq --count | sort --numeric --reverse \
| awk '{printf "%3s copies of lead %s\n", $1, $2}'
