Example Code

from fds.sdk.utils.authentication import ConfidentialClient

import fds.sdk.IRNNotes
from fds.sdk.IRNNotes.api import attachments_api
from fds.sdk.IRNNotes.models import *
from dateutil.parser import parse as dateutil_parser
from pprint import pprint

# See configuration.py for a list of all supported configuration parameters.

# Examples for each supported authentication method are below,
# choose one that satisfies your use case.

# (Preferred) OAuth 2.0: FactSetOAuth2
# See https://github.com/FactSet/enterprise-sdk#oauth-20
# for information on how to create the app-config.json file
#
# The confidential client instance should be reused in production environments.
# See https://github.com/FactSet/enterprise-sdk-utils-python#authentication
# for more information on using the ConfidentialClient class
configuration = fds.sdk.IRNNotes.Configuration(
    fds_oauth_client=ConfidentialClient('/path/to/app-config.json')
)

# Basic authentication: FactSetApiKey
# See https://github.com/FactSet/enterprise-sdk#api-key
# for information how to create an API key
# configuration = fds.sdk.IRNNotes.Configuration(
#     username='USERNAME-SERIAL',
#     password='API-KEY'
# )

# Enter a context with an instance of the API client
with fds.sdk.IRNNotes.ApiClient(configuration) as api_client:
    # Create an instance of the API class
    api_instance = attachments_api.AttachmentsApi(api_client)
    note_id = "noteId_example" # str | Note Id
    file = open('/path/to/file', 'rb') # file_type | 

    try:
        # Create an attachment for an existing note
        # example passing only required values which don't have defaults set
        api_response = api_instance.create_attachment(note_id, file)

        pprint(api_response)
    except fds.sdk.IRNNotes.ApiException as e:
        print("Exception when calling AttachmentsApi->create_attachment: %s\n" % e)

    # # Get response, http status code and response headers
    # try:
    #     # Create an attachment for an existing note
    #     api_response, http_status_code, response_headers = api_instance.create_attachment_with_http_info(note_id, file)


    #     pprint(api_response)
    #     pprint(http_status_code)
    #     pprint(response_headers)
    # except fds.sdk.IRNNotes.ApiException as e:
    #     print("Exception when calling AttachmentsApi->create_attachment: %s\n" % e)

    # # Get response asynchronous
    # try:
    #     # Create an attachment for an existing note
    #     async_result = api_instance.create_attachment_async(note_id, file)
    #     api_response = async_result.get()


    #     pprint(api_response)
    # except fds.sdk.IRNNotes.ApiException as e:
    #     print("Exception when calling AttachmentsApi->create_attachment: %s\n" % e)

    # # Get response, http status code and response headers asynchronous
    # try:
    #     # Create an attachment for an existing note
    #     async_result = api_instance.create_attachment_with_http_info_async(note_id, file)
    #     api_response, http_status_code, response_headers = async_result.get()


    #     pprint(api_response)
    #     pprint(http_status_code)
    #     pprint(response_headers)
    # except fds.sdk.IRNNotes.ApiException as e:
    #     print("Exception when calling AttachmentsApi->create_attachment: %s\n" % e)

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.IRNNotes

logging.basicConfig(level=logging.DEBUG)

configuration = fds.sdk.IRNNotes.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.IRNNotes

configuration = fds.sdk.IRNNotes.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.IRNNotes

configuration = fds.sdk.IRNNotes.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.IRNNotes

configuration = fds.sdk.IRNNotes.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.IRNNotes.apis and fds.sdk.IRNNotes.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.IRNNotes.api.default_api import DefaultApi
• from fds.sdk.IRNNotes.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.IRNNotes
from fds.sdk.IRNNotes.apis import *
from fds.sdk.IRNNotes.models import *
