Can't retrieve buy crypto transactions from API


I want to retrieve my crypto buy transactions using the API, however when I try to retrieve it using the endpoint /sapi/v1/fiat/orders I always have an empty response.

As you can see in the attached image I have two transactions between 2022-02-01 and 2022-04-19.

Here is the code sample I’m using to reproduce the issue.

#!/usr/bin/python3 -u

from urllib.parse import urlencode
import datetime
import requests
import hashlib
import hmac
import time
import json

class BinanceConnector:

    def __init__(self, api_key, api_secret):
        self.api_key = api_key
        self.api_secret = api_secret
        self.session = requests.Session()
            "Content-Type": "application/json;charset=utf-8",
                "X-MBX-APIKEY": self.api_key,
        self.url = ""

    def __request(self, method, path, payload={}, auth=False):
        url = '%s%s' % (self.url, path)

        if auth:
            payload["timestamp"] = self.__get_timestamp()
            query_string = self.__query_string(payload)
            signature = self.__generate_signature(query_string)
            payload['signature'] = signature

        params = {"url": url}
        if payload:
            params["params"] = self.__query_string(payload)


        response = self._dispatch_request(method)(**params)
        return response

    def _dispatch_request(self, http_method):
        return {
            "GET": self.session.get,
            "DELETE": self.session.delete,
            "PUT": self.session.put,
        }.get(http_method, "GET")

    def __get_timestamp(self):
        return int(time.time() * 1000)

    def __generate_signature(self, data):
        hash ="utf-8"), data.encode("utf-8"), hashlib.sha256)
        return hash.hexdigest()

    def __query_string(self, query):
        if query == None:
            return ''
            filtered_query = {}
            for key in query.keys():
                if query[key] is not None:
                    filtered_query[key] = query[key]
            return urlencode(filtered_query, True).replace("%40", "@")

    def get_fiat_deposit(self):

        begin_time = datetime.datetime(2022, 2, 1, 12, 0, 0)
        begin_time_timestamp = int(round(begin_time.timestamp()))*1000

        end_time = datetime.datetime(2022, 4, 19, 12, 0, 0)
        end_time_timestamp = int(round(end_time.timestamp()))*1000

        payload = {
            "transactionType": 0,
            "beginTime": begin_time_timestamp,
            "endTime": end_time_timestamp,

        response = self.__request("GET", "/sapi/v1/fiat/orders", payload=payload, auth=True)
        return response


connector = BinanceConnector(my_api_key, my_secret_key)

response = connector.get_fiat_deposit()

print(json.dumps(response.json(), indent=4))

And here is the output

$ ./
{'transactionType': 0, 'beginTime': 1643713200000, 'endTime': 1650362400000, 'timestamp': 1658143239445, 'signature': '6499ce486918fe199dacfb6937ee8b09dd3808bfb672c58ab55fcbf31851a19f'}
    "code": "000000",
    "message": "success",
    "data": [],
    "total": 0,
    "success": true

Both beginTime and endTime fields seems to be correctly composed, however the response doesn’t contains any order.

Does anybody knows why I don’t have any order returned ?

Thanks in advance.

The Fiat Order History endpoint does not return the Buy Crypto History, but the transaction history for fiat deposits and withdrawals.

You are right, my bad, I should have used /sapi/v1/fiat/payments endpoint.

Thanks :slight_smile:
