The official python client library for the Plaid API, which is generated from our OpenAPI spec.
This library only supports python3!
$ pip3 install plaid-pythonThis release only supports the latest Plaid API version, 2020-09-14.
For information about what has changed between versions and how to update your integration, head to the API upgrade guide.
The plaid-python client library is typically updated on a monthly basis. The canonical source for the latest version number is the client library changelog. New versions are published as GitHub tags, not as Releases. New versions are also published on PyPi. Plaid uses semantic versioning to version the client libraries, with potentially breaking changes being indicated by a major version bump.
All users are strongly recommended to use a recent version of the library, as older versions do not contain support for new endpoints and fields. For more details, see the Migration Guide.
To call an endpoint you must create a PlaidApi object.
import plaid
from plaid.api import plaid_api
# Available environments are
# 'Production'
# 'Development'
# 'Sandbox'
configuration = plaid.Configuration(
host=plaid.Environment.Sandbox,
api_key={
'clientId': client_id,
'secret': secret,
}
)
api_client = plaid.ApiClient(configuration)
client = plaid_api.PlaidApi(api_client)Each endpoint returns a dictionary which contains the parsed JSON from the HTTP response.
All non-200 responses will throw a plaid.ApiException.
import plaid
from plaid.model.asset_report_get_request import AssetReportGetRequest
try:
request = AssetReportGetRequest(
asset_report_token=asset_report_token,
)
return client.asset_report_get(request)
except plaid.ApiException as e:
response = json.loads(e.body)
# check the code attribute of the error to determine the specific error
if response['error_code'] == 'ITEM_LOGIN_REQUIRED':
# the users' login information has changed, generate a public_token
# for the user and initialize Link in update mode to
# restore access to this user's data

As this is a common question, we've included this in the README. plaid-python uses models like TransactionsSyncResponse to encapsulate API responses. If you want to convert this to a JSON, do something like this:
import json
...
response = ... # type TransactionsSyncResponse
# to_dict makes it first a python dictionary, and then we turn it into a string JSON.
json_string = json.dumps(response.to_dict(), default=str)Dates and datetimes in requests, which are represented as strings in the API and in previous client library versions, are represented in this version of the Python client library as Python datetime.date or datetime.datetime objects. If you need to convert between dates and strings, you can use the datetime.strptime method. For an example, see the Retrieve Transactions sample code later in this Readme. For more information on the Python's datetime module, see Python's official documentation.
Note that the datetime.strptime method will silently remove time zone information. Time zone information is required for request fields that accept datetimes. Failing to include time zone information (or passing in a string, instead of a datetime.datetime object) will result in an error. See the following examples for guidance on datetime.date and datetime.datetime usage.
If the API reference documentation for a field specifies format: date, either of following are acceptable:
from datetime import date
a = date(2022, 5, 5)
b = date.fromisoformat('2022-05-05')If the API reference documentation for a field specifies format: date-time, the following is acceptable:
from datetime import datetime
a = datetime(2022, 5, 5, 22, 35, 49, tzinfo=datetime.timezone.utc)For more examples, see the test suites, Quickstart, or API Reference documentation.
Exchange a public_token from Plaid Link for a Plaid access token:

from plaid.model.item_public_token_exchange_request import ItemPublicTokenExchangeRequest
# the public token is received from Plaid Link
exchange_request = ItemPublicTokenExchangeRequest(
public_token=pt_response['public_token']
)
exchange_response = client.item_public_token_exchange(exchange_request)
access_token = exchange_response['access_token']import plaid

# Provide the access token for the Item you want to remove
request = ItemRemoveRequest(
access_token=accessToken
)

# retrieve all transactions
while (response['has_more']):
request = TransactionsSyncRequest(
access_token=access_token,
cursor=response['next_cursor']
)
response = client.transactions_sync(request)

FILE.close()Migrating from version 8.0.0 or later of the library to a recent version should involve very minor integration changes. Many customers will not need to make changes to their integrations at all. To see a list of all potentially-breaking changes since your current version, see the client library changelog and search for "Breaking changes in this version". Breaking changes are annotated at the top of each major version header.
Version 8.0.0 of the client library was released in August 2021 and contains multiple interface changes, as described below.

While the API and previous library versions prior to 8.0.0 represent enums using strings, this current library uses Python classes with restricted values.
From:
'products': ['auth', 'transactions'],
'country_codes': ['US'],
To:
products=[Products('auth'), Products('transactions')],
country_codes=[CountryCode('US')],
Some configuration options, including request timeouts, have moved from global (client-level) to being specified a per-request level, and additional configuration options have been added.
Global configuration options: configuration.py Per-request configuration options: api_client.py
From:
class PlaidClient(plaid.Client):
def __init__(
self,
...
timeout=60
):
...
To:
response = client.accounts_balance_get(request, _request_timeout=60)
