list of all eBay categories and eBay category ids

it's strange that a company like eBay doesn't make it easy for sellers to get the resources they need. have you tried getting a complete list of all eBay categories? maybe with the eBay category tree? - you will find that there's not a convenient download location, albeit there should be!

the "trick" so i've learned is to get it yourself.

here is a very short python script that will get your categories:

#! /usr/bin/env python
import tools as t
import xmltodict as xml
import requests
url = '{}&siteid={}&CategoryID={}&version=729&IncludeSelector=ChildCategories'
app_id = 'XXXX' #get your own eBay app id
site_id = '3' # 3 is UK
to_get = [-1] # start at the top
done = []
categories = {}
if __name__ == "__main__":
    while len(to_get) > 0:
        cid = to_get.pop()
        re = requests.get(url.format(app_id, site_id, cid))
        root = xml.parse(re.text)
        cats = root['GetCategoryInfoResponse']['CategoryArray']['Category']
        for cat in cats:
            if cat['CategoryID'] not in categories:
                print(cat.get('CategoryName', 0))
                c = {'category_id': cat.get('CategoryID', 0),
                    'category_level': cat.get('CategoryLevel', 0),
                    'category_name': cat.get('CategoryName', 0),
                    'category_parent_id': cat.get('CategoryParentID', 0),
                    'leaf_category': cat.get('LeafCategory', 0),
                    'category_name_path': cat.get('CategoryNamePath', 0)}
                categories[cat['CategoryID']] = c
            if cat['CategoryID'] not in done  and cat['LeafCategory'] == 'false' :
    with open('eBay_categories.tsv', 'w', encoding="utf-8") as of:
        for k,v in categories.items():
            of.write(str(v['category_id']) + "\t" + str(v['category_level']) + "\t" + str(v['category_name']) + "\t" + str(v['category_parent_id']) + "\t" + str(v['leaf_category']) + "\t" + str(v['category_name_path']) + "\n")

the above will then create a tab delimited text file named 'eBay_categories.tsv'.
please note you will need both the "requests" and the "xmltodict" modules. they can be easily obtained using pypi. this code is python 3
