A few months ago I followed this Scrapy shell method to scrape a real estate listings webpage and it worked perfectly.
I pulled my cookie and user-agent text from Firefox (Developer tools -> Headers) when the target URL is loaded, and I would get a successful response (200) and be able to pull items from response.xpath.
For example:

url = 'https://www.realtor.com/realestateandhomes-search/McLean_VA/type-single-family-home/pg-1?pos=39.126499,-77.43902,38.685678,-76.779841,11&qdm=true'2

(fetch(scrapy.Request(url=url, headers={'cookie': cookie, 'user-agent': user_agent})), response)6
listings = json.loads(response.xpath('/html/body/script[1]/text()').getall()[0])['props']['pageProps']['searchResults']['home_search']['results']7
Now I’m trying again a few months later (with an updated cookie) and I’m getting a 403 error — the server understands the request but refuses to authorize it:

Out[7]: (None, None)5
Any thoughts on what I might try to get this working again? Thanks.

The cookie is not what’s causing the problem. (see below) I think the issue here is that with ‘view=map’, its looking for a ‘referer’ key in the header dict (in addition to other header keys). I would suggest adding a key/pair of ‘referer’:”url” in your headers. Alternatively you can try less heavy approach:
