Using Pandas

To convert an API response to a Pandas DataFrame, it is necessary to transform it first to a dictionary.

import pandas as pd

response_dict = api_response.to_dict()['data']

simple_json_response = pd.DataFrame(response_dict)
nested_json_response = pd.json_normalize(response_dict)

Debugging

The SDK uses the standard library logging module.

Setting debug to True on an instance of the Configuration class sets the log-level of related packages to DEBUG and enables additional logging in Pythons HTTP Client.

Note: This prints out sensitive information (e.g. the full request and response). Use with care.

import logging
import fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST

logging.basicConfig(level=logging.DEBUG)

configuration = fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.Configuration(...)
configuration.debug = True

Configure a Proxy

You can pass proxy settings to the Configuration class:

• proxy: The URL of the proxy to use.
• proxy_headers: a dictionary to pass additional headers to the proxy (e.g. Proxy-Authorization).

import fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST

configuration = fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.Configuration(
    # ...
    proxy="http://secret:password@localhost:5050",
    proxy_headers={
        "Custom-Proxy-Header": "Custom-Proxy-Header-Value"
    }
)

Custom SSL Certificate

TLS/SSL certificate verification can be configured with the following Configuration parameters:

• ssl_ca_cert: a path to the certificate to use for verification in PEM format.
• verify_ssl: setting this to False disables the verification of certificates. Disabling the verification is not recommended, but it might be useful during local development or testing.

import fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST

configuration = fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.Configuration(
    # ...
    ssl_ca_cert='/path/to/ca.pem'
)

Request Retries

In case the request retry behaviour should be customized, it is possible to pass a urllib3.Retry object to the retry property of the Configuration.

from urllib3 import Retry
import fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST

configuration = fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.Configuration(
    # ...
)

configuration.retries = Retry(total=3, status_forcelist=[500, 502, 503, 504])

Notes for Large OpenAPI documents

If the OpenAPI document is large, imports in fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.apis and fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.models may fail with a RecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:

Solution 1: Use specific imports for apis and models like:

• from fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.api.default_api import DefaultApi
• from fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.model.pet import Pet

Solution 2: Before importing the package, adjust the maximum recursion limit as shown below:

import sys
sys.setrecursionlimit(1500)
import fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST
from fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.apis import *
from fds.sdk.BestExecutionAnalyticsforSmarterTradingBEAST.models import *
