Python request vs curl

I'm trying to extract data from URL using POST with specific headers and body payload. Using curl or a tool like Advanced Rest Client, I'm able to get the JSON containing the data I want and the pretty code 200. However, if I try doing the same request using python requests, it won't work. I get a code 405 and bad json.

These are the configs I'm using:

curl -H "Content-Type: application/json" --data @payload.json -X POST https://www.walmart.com/terra-firma/fetch?rgs=REVIEWS_MAP

the json file payload.json, looks like this:

{"productId":"10VJLBWPW82T","paginationContext":{"sort":"relevancy","page":3}}

And here is the python3 code:

import requests

url = "http://www.walmart.com/terra-firma/fetch?rgs=REVIEWS_MAP"

head = {'Content-type':'application/json'}
payload = {"productId":"10VJLBWPW82T","paginationContext":{"sort":"relevancy","page":3}}

rep = requests.post(url, headers=head, data=payload)

Does anybody know how to explain this difference ?

Two things, first use the 'json' parameter in the request not 'data' for posting json. Secondly use https not http protocol for this particular web-page.

import requests

url = "https://www.walmart.com/terra-firma/fetch?rgs=REVIEWS_MAP"
head = {'Content-type':'application/json'}
payload = {"productId":"10VJLBWPW82T","paginationContext":{"sort":"relevancy","page":3}}
rep = requests.post(url, headers=head, json=payload)
print (rep.status_code)
print (rep.json())

Outputs:
