Updates to HOPCOMS API

HOPCOMS Daily rate page moved to a new location last month. It’s not visible on Google search and hence I couldn’t find. But a good soul at HOPCOMS whom I got in touch with sent me this new link. It’s not just change of url. They have changed the structure of the data published and they have also changed the Item Code1. This brings me a new problem as in my HOPCOMS API I publish rates against item code.

HOPCOMS API

So there is a new item code list here item_list2.csv which is valid for any data published from 20190923 (2019 Sept 23). For anything before 20190923 use item_list.csv.

They have also removed the reporting part. I will try and build a simple reporting feature with the data I have. Also I have a month’s data missing as of now. I will make a request for it. Let’s see how it goes.

As usual all the data and code are on github. But here is the new daily scraper code.

import requests

all_items_load = False
all_item_list = {}
hopcoms_meta 	= couch["hopcoms_meta"]

if all_items_load:
	with open('item_list2.csv', "r") as csv_file:

	print str(total_data)
	hopcoms_daily.save(total_data)

  1. Very few items have same item code
