This code will grab observations from the iNaturalist API for Vashon Biodiversity Proj

iNaturalist API get observations api instructions: https://api.inaturalist.org/v1/docs/#!/Observations/get_observations

includes lists of parameters and descriptions

all individual observations are stored in a list called observations each observation is a json object

import requests
import json

    "order_by": "id",
    "order": "asc"
}

# get data
# observations is list with each observation json object as an element
response = requests.get(url, params=params)

# Store the last ID
