Timestamp not in ISO8601 format. Amazon MWS and Python - python

I'm trying to make a simple SubmitFeed, but I'm getting an error that says "Timestamp must be in ISO8601 format". This is what I have:
def make_update_feed(host, seller_id, mws_auth_token, aws_access_key_id, secret_key, xml):
date_now = dt.utcnow().replace(microsecond=0).isoformat() + "Z"
xml_md5_b64 = md5_b64_hash(xml)
timestamp = urllib.quote_plus(date_now)
params = "AWSAccessKeyId={0}&Action=SubmitFeed&ContentMD5Value={1}&FeedType=_POST_INVENTORY_AVAILABILITY_DATA_&MWSAuthToken={2}&Merchant={3}&PurgeAndReplace=false&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp={4}&Version=2009-01-01".format(aws_access_key_id,urllib.quote_plus(xml_md5_b64),mws_auth_token,seller_id,timestamp)
string_2_sign = "POST\n{0}\n/\n{1}".format(host,params)
signature = hmac_sha256_b64(string_2_sign, secret_key)
params_req = {
"AWSAccessKeyId": urllib.quote_plus(aws_access_key_id),
"Action": "SubmitFeed",
"ContentMD5Value": urllib.quote_plus(xml_md5_b64),
"FeedType": "_POST_INVENTORY_AVAILABILITY_DATA_",
"MWSAuthToken": urllib.quote_plus(mws_auth_token),
"Merchant": urllib.quote_plus(seller_id),
"PurgeAndReplace": False,
"SignatureMethod": "HmacSHA256",
"SignatureVersion": 2,
"Timestamp": timestamp,
"Version": "2009-01-01",
"Signature": urllib.quote_plus(signature),
}
headers = {
'Host': urllib.quote_plus(host),
'Content-Type': "text/xml",
"x-amazon-user-agent": "MyPythonApp/1.0 (Language=Python)"
}
data_xml = {
'FeedContent': xml
}
url = "https://%s" % host
r = requests.post(url, params=params_req, headers=headers,data=data_xml)
return r
Now, when I run my function with the respective parameters, I get this response:
<?xml version="1.0"?>
<ErrorResponse xmlns="http://mws.amazonaws.com/doc/2009-01-01/">
<Error>
<Type>Sender</Type>
<Code>InvalidParameterValue</Code>
<Message>Timestamp 2018-02-19T14%3A30%3A50Z must be in ISO8601 format</Message>
</Error>
<RequestID>7c8631e4-8d61-4f46-9256-af0130028d96</RequestID>
</ErrorResponse>
However, I can see that the timestamp is in ISO8601 format. I don't know why it's giving me that error. Also, both the xml hash and the signature are correct (I checked vs Amazon Scratchpad, and they were the same). Any ideas?

Payload from a defined list in Python

I am pretty new to python and I am trying to create a script that will pull data from a ticketing platform.
I got the list of agents and their ids but when I try to pull the data it's giving me this error:
KeyError: 'data'
Is there a way for me to have the parameter "agents": to automatically update using the agent_id list?
Here is the code, I removed the links and the API key for privacy reasons:
import requests
import json
from cgitb import text
from openpyxl import Workbook
import openpyxl
import requests
from datetime import date
from datetime import timedelta
#Agents list
agents_list = ["Agent1", "Agent2", "Agent3"]
agent_id = []
agents_names = []
today = date.today()
yesterday = today - timedelta(days = 1)
start_date = str(yesterday)
end_date = str(yesterday)
def extragere_date_agenti():
url = "https://x.gorgias.com/api/users?limit=100&order_by=name%3Aasc&roles=agent&roles=admin"
headers = {
"accept": "application/json",
"authorization": "Basic"
}
response = requests.get(url, headers=headers)
text_name_id = json.loads(response.text)
for names in text_name_id["data"]:
agent_name = names["firstname"]
agents_id = names["id"]
if agent_name in agents_list:
agents_names.append(agent_name)
agent_id.append(agents_id)
extragere_date_agenti()
def extragere_numere():
url = "https://x.gorgias.com/api/stats/total-messages-sent"
payload = {"filters": {
"period": {
"start_datetime": start_date + "T00:00:00-05:00",
"end_datetime": end_date + "T23:59:59-05:00"
},
"agents": [agent_id], #This is the value that I want to modify
"channels": ["email"]
}}
headers = {
"accept": "application/json",
"content-type": "application/json",
"authorization": "Basic"
}
response = requests.post(url, json=payload, headers=headers)
text_numere = json.loads(response.text)
numere_finale = text_numere["data"]["data"]["value"]
print(numere_finale)
I've tried to do a for loop but it's giving me the same error. Any suggestions?
First, add the condition to check the response status code
Also, add another condition to prevent this type of key error:
if "data" in text_name_id:
Your Error:
KeyError: 'data'
Means that in text_name_id is no Key named "data".
Difficult to tell you how to fix it without any more info...
Are you sure, that request returns a positiv status?? I see no ErrorHandling, if respone.status_code == 200: should be enough to check.
Are you sure that the response json has a Key named "data"? Try this to set a default if key is missing:
text_name_id.get("data", [{"firstname": "error", "id": 0}])
--- Edit ---
Okay, is that the right one I don't see a "id" or "firstname" key. But if it is the right JSON, than you can't iterate over dict like you did in Python.
To do so you would want to do this:
for key, value in text_name_id['data']['data'].items():

How to export offer file from Bol Retailer API using Python

I have been trying to export offer file using Python for Bol Retailer API
According to the official docs on request an offer file export
I have include all the headers and formats but it throws a 400 Bad Request
400
Bad Request
b'{\n "type" : "https://api.bol.com/problems",\n "title" : "Bad Request",\n "status" : 400,\n "detail" : "The supplied content-type media type is not supported.",\n "host" : "Instance-111",\n "instance" : "https://api.bol.com/retailer/offers/export"\n}'
Here is a minimal example from my code
import base64
import requests
import json
import time
class BolService:
def __init__(self, _id, secret):
self.host = "https://api.bol.com"
self.__header = {
"Accept": "application/vnd.retailer.v7+json",
"Content-Type": "N/A",
"Authorization": "Bearer " + self.__get_token(_id, secret)
}
def __get_token(self, _id, secret) -> str:
creds = (_id + ":" + secret).encode('ascii') #creds : ascii bytes
creds_b64_b = base64.b64encode(creds) #creds : base64 bytes
creds_b64 = creds_b64_b.decode('ascii') #creds : base64 string
header = {
"Authorization":"Basic " + creds_b64
}
link = "https://login.bol.com/token?grant_type=client_credentials"
response = requests.post(link, headers=header)
response_data = json.loads(response.content.decode())
return response_data['access_token']
def get_offer_file(self):
path = f"/retailer/offers/export"
new_header = self.__header.copy()
new_header["format"] = "CSV"
response = requests.post(self.host + path, headers=new_header)
return response
Note: I have also tried changing the "Content-Type" in self.__header to "application/vnd.retailer.v7+json", I have also changed the same to add csv using "application/vnd.retailer.v7+json+csv" or "application/vnd.retailer.v7+csv". I have also tried adding self.__header['Content-Type'] = 'text/csv' but nothing seems to work it keeps on throwing the same Bad Request. I have also tried using the v6 of the API instead of v7 but same issue.
I know this is something that should be dealt with the customer service of Bol but they their service is too pathetic to even give a simple reply. Also as of August 2022 their site which details API issues is down. Maybe if someone with experience can help here.
I don't think I am missing anything here. Please let me know.
So I was able to sucessfully make the POST request.
1st what I did was change the "Content-Type" in self.__header to "application/vnd.retailer.v7+json"
so the header now looks like this
self.__header = {
"Accept": "application/vnd.retailer.v7+json",
"Content-Type": "application/vnd.retailer.v7+json",
"Authorization": "Bearer " + self.__get_token(_id, secret)
}
Since we require the content type in JSON format so we have to include a JSON body by dumping our dictionary content using json.dumps
So the get_offer_file method now looks like with {"format":"CSV"} as the body
def get_offer_file(self):
path = f"/retailer/offers/export"
response = requests.post(self.host + path, headers=self.__header, data=json.dumps({"format":"CSV"}))
return response
Here is the full code:
import base64
import requests
import json
class BolService:
def __init__(self, _id, secret):
self.host = "https://api.bol.com"
self.__header = {
"Accept": "application/vnd.retailer.v7+json",
"Content-Type": "application/vnd.retailer.v7+json",
"Authorization": "Bearer " + self.__get_token(_id, secret)
}
def __get_token(self, _id, secret) -> str:
creds = (_id + ":" + secret).encode('ascii') #creds : ascii bytes
creds_b64_b = base64.b64encode(creds) #creds : base64 bytes
creds_b64 = creds_b64_b.decode('ascii') #creds : base64 string
header = {
"Authorization":"Basic " + creds_b64
}
link = "https://login.bol.com/token?grant_type=client_credentials"
response = requests.post(link, headers=header)
response_data = json.loads(response.content.decode())
return response_data['access_token']
def get_offer_file(self):
path = f"/retailer/offers/export"
response = requests.post(self.host + path, headers=self.__header, data=json.dumps({"format":"CSV"}))
return response

Signed request with python to binance future

I have been struggling to send a signed request to binance future using signature.
I found that example code on StackOverflow ("Binance API call with SHA56 and Python requests") and an answer has been given to it mentioning to use hmac
as below: but unfortunately i still don't see how to write this example. Could anyone show how the code of this example should look like? i am really uncomfortable with signed request. Thanks a lot for your understanding and your help advice given:
params = urlencode({
"signature" : hashedsig,
"timestamp" : servertimeint,
})
hashedsig = hmac.new(secret.encode('utf-8'), params.encode('utf-8'), hashlib.sha256).hexdigest()
Original example:
import requests, json, time, hashlib
apikey = "myactualapikey"
secret = "myrealsecret"
test = requests.get("https://api.binance.com/api/v1/ping")
servertime = requests.get("https://api.binance.com/api/v1/time")
servertimeobject = json.loads(servertime.text)
servertimeint = servertimeobject['serverTime']
hashedsig = hashlib.sha256(secret)
userdata = requests.get("https://api.binance.com/api/v3/account",
params = {
"signature" : hashedsig,
"timestamp" : servertimeint,
},
headers = {
"X-MBX-APIKEY" : apikey,
}
)
print(userdata)
The proper way would be:
apikey = "myKey"
secret = "mySecret"
servertime = requests.get("https://api.binance.com/api/v1/time")
servertimeobject = json.loads(servertime.text)
servertimeint = servertimeobject['serverTime']
params = urlencode({
"timestamp" : servertimeint,
})
hashedsig = hmac.new(secret.encode('utf-8'), params.encode('utf-8'),
hashlib.sha256).hexdigest()
userdata = requests.get("https://api.binance.com/api/v3/account",
params = {
"timestamp" : servertimeint,
"signature" : hashedsig,
},
headers = {
"X-MBX-APIKEY" : apikey,
}
)
print(userdata)
print(userdata.text)
Make sure to put the signature as the last parameter or the request will return [400]...
Incorrect:
params = {
"signature" : hashedsig,
"timestamp" : servertimeint,
}
Correct:
params = {
"timestamp" : servertimeint,
"signature" : hashedsig,
}
At the time of writing, Binance themselves are mainting a repo with some examples*, using the requests library. Here is a sample in case the link goes down or is moved:
import hmac
import time
import hashlib
import requests
from urllib.parse import urlencode
KEY = ''
SECRET = ''
# BASE_URL = 'https://fapi.binance.com' # production base url
BASE_URL = 'https://testnet.binancefuture.com' # testnet base url
''' ====== begin of functions, you don't need to touch ====== '''
def hashing(query_string):
return hmac.new(SECRET.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()
def get_timestamp():
return int(time.time() * 1000)
def dispatch_request(http_method):
session = requests.Session()
session.headers.update({
'Content-Type': 'application/json;charset=utf-8',
'X-MBX-APIKEY': KEY
})
return {
'GET': session.get,
'DELETE': session.delete,
'PUT': session.put,
'POST': session.post,
}.get(http_method, 'GET')
# used for sending request requires the signature
def send_signed_request(http_method, url_path, payload={}):
query_string = urlencode(payload)
# replace single quote to double quote
query_string = query_string.replace('%27', '%22')
if query_string:
query_string = "{}&timestamp={}".format(query_string, get_timestamp())
else:
query_string = 'timestamp={}'.format(get_timestamp())
url = BASE_URL + url_path + '?' + query_string + '&signature=' + hashing(query_string)
print("{} {}".format(http_method, url))
params = {'url': url, 'params': {}}
response = dispatch_request(http_method)(**params)
return response.json()
# used for sending public data request
def send_public_request(url_path, payload={}):
query_string = urlencode(payload, True)
url = BASE_URL + url_path
if query_string:
url = url + '?' + query_string
print("{}".format(url))
response = dispatch_request('GET')(url=url)
return response.json()
response = send_signed_request('POST', '/fapi/v1/order', params)
print(response)
Some additional thoughts from myself:
You can also use a new library also from Binance called Binance connector. It is a bit new, it has some issues, but it can do the basic operations without you worrying about signed requests.
I wouldn't use serverTime because that means you need to make an additional request and networks can be slow, I'd follow this example and use the int(time.time() * 1000) you may not even need the function.
I purposedly used the POST example, because this is more complicated as you need to also encode and hash your custom parameters
At the time of writing, v3 is the latest version
Hope it helps.

archive Microsoft team with Microsoft graph

I try to archive a Microsoft team
$scopes = 'Group.ReadWrite.All'
$appid = ‘’
$appsecret = ''
$appaaddomain = ''
$url = "https://graph.microsoft.com/v1.0/teams/{team-id}/archive"
…
Invoke-RestMethod -Method "Post" -Uri $url -Headers #{Authorization = "Bearer $token"
I become 403 error.
{
"error": {
"code": "AccessDenied",
"message": "Unable to fetch team thread: Failed to execute Skype backend request GetThreadRequest.",

"date": "2019-03-03T23:18:55"
}
} }
What I do wrong?
Delete the team will work
$scopes = 'Group.ReadWrite.All'
$appid = ‘’
$appsecret = ''
$appaaddomain = ''
$url = "https://graph.microsoft.com/v1.0/groups/{team-id}"
…
Invoke-RestMethod -Method "Delete" -Uri $url -Headers #{Authorization = "Bearer $token"
The same result came with the Microsoft graph explorer (here I give me all possible permissions)
I don't see anything wrong with your approach -- I've included the Python code I use to archive Teams below, and the same process appears to be used in your code. This could be a transient error. I got the same message a few days ago when some change precluded new channels from being created (even in the GUI).

Generate HMAC Sha256 in python 3

I write code to verify an HMAC Auth incoming POST request with JSON to our API. The HMAC I received is OD5ZxL4tdGgWr78e9vO3cYrjuOFT8WOrTbTIuuIH1PQ=
When I try to generate it by my self using Python, it is always different.
Here is the JSON request I received:
{
"shipper_id": 4841,
"status": "Cancelled",
"shipper_ref_no": "",
"tracking_ref_no": "",
"shipper_order_ref_no": "",
"timestamp": "2018-05-23T15:13:28+0800",
"id": "61185ecf-3484-4985-b625-ffe30ba36e28",
"previous_status": "Pending Pickup",
"tracking_id": "NVSGBHINK000000001"
}
And the client secret is 817a3723917f4c7fac24b1f1b324bbab.
The HMAC secret I received is OD5ZxL4tdGgWr78e9vO3cYrjuOFT8WOrTbTIuuIH1PQ=.
Here is the code when I write it in PHP:
<?php
define('CLIENT_SECRET', 'my_shared_secret');
function verify_webhook($data, $hmac_header){
$calculated_hmac = base64_encode(hash_hmac('sha256', $data, CLIENT_SECRET, true));
return ($hmac_header == $calculated_hmac);
}
$hmac_header = $_SERVER['X-NINJAVAN-HMAC-SHA256'];
$data = file_get_contents('php://input');
$verified = verify_webhook($data, $hmac_header);
error_log('Webhook verified: '.var_export($verified, true)); //check error.log to see result
?>
But I have no idea how to do it in Python 3.
In Python 3 you basically want something like the following, taken from how you handle GitHub webhook requests.
import hashlib
import hmac
secret = 'CLIENT_SECRET'
data = rsp.content # assumes you're using requests for data/sig
signature = rsp.headers['X-Something-Signature']
signature_computed = 'sha1=' + hmac.new(
key=secret.encode('utf-8'),
msg=data.encode('utf-8'),
digestmod=hashlib.sha1
).hexdigest()
if not hmac.compare_digest(signature, signature_computed):
log("Invalid payload")
If you want to recreate the hashing code from PHP to Python do it thusly:
def create_signature(key, data):
sig_hash = hmac.new(key.encode('utf8'), data.encode('utf8'), hashlib.sha256).digest()
base64_message = base64.b64encode(sig_hash).decode()
return base64_message
This will create the signature that should match what your PHP code is creating. Just compare the signature to what is sent in the header.
from collections import OrderedDict
