how to POST contents of JSON file to RESTFUL API with Python using requests module

This should work, but it's meant for very large files.

import requests

url = 'https://api.example.com/api/dir/v1/accounts/9999999/orders'
headers = {'Authorization' : ‘(some auth code)’, 'Accept' : 'application/json', 'Content-Type' : 'application/json'}
r = requests.post(url, data=open('example.json', 'rb'), headers=headers)

If you want to send a smaller file, send it as a string.

contents = open('example.json', 'rb').read()
r = requests.post(url, data=contents, headers=headers)

First of all your json file does not contain valid json. as in,"id”-here the closing quotation mark is different than the opening quotation mark. And other ID fields have the same error. Make it like this "id".

now you can do it like this,

import requests
import json
with open('example.json') as json_file:
    json_data = json.load(json_file)

headers = {'Authorization' : ‘(some auth code)’, 'Accept' : 'application/json', 'Content-Type' : 'application/json'}

r = requests.post('https://api.example.com/api/dir/v1/accounts/9999999/orders', data=json.dumps(json_data), headers=headers)
