I get a 302 status code response but with its body empty

I’m using scrapy so this is not the whole working code, I have another .py to instantiate this class and run .ninjaresponse() method. Anyway you can see the 302 status code in response.text, which doesn’t return requested html

class ScrapeNinja():
ninja_url = ‘https://scrapeninja.p.rapidapi.com/scrape’

# get your subscription key at https://rapidapi.com/restyler/api/scrapeninja from "Code generator",
# copy&paste it to 'x-rapidapi-key' header below
def __init__(self,url):
    self.payload['url'] = url[0]
    self.payload['headers'][0] = f"referer: {url[0]}"

headers = {
    "Content-Type": "application/json",
    "x-rapidapi-host": "scrapeninja.p.rapidapi.com",
    "x-rapidapi-key": "xxxxx"
}
