dwolla 2.3.2

An official requests based wrapper for the Dwolla API

About Dwolla

Dwolla is a software platform that makes it easy to move money between banks. When using Dwolla APIs your software platform can move money between any 2 bank accounts, or network members, with no per transaction fees.

Our software platform is compatibale with all banks in the United States. The developer documents are designed to support our development partners who are building on top of Dwolla’s branded platform (v1) or our white labeled infrastructure (v2).

The Dwolla API developer portal lives here:

Our API portal is available on GitHub here:

Our v1 API documentation is available here:

Our v2 API documentation is available here:

|Build Status|

The new and improved Dwolla library based off of the Python requests client. dwolla-python includes support for all API endpoints, and is the new library officially supported by Dwolla.




dwolla-python is available on PyPi, and therefore can be installed automagically via pip.

The Python “requests“ library is required for “dwolla-python“ to operate. It is included as a dependency on this package if your environment does not already have it.

To install via pip:

pip install dwolla

To add to “requirements.txt“ and make this a permanent dependency of your package:

requirements.txt YourApp SomeLibrary==1.2.3 dwolla>=2.0.0 pip install -r requirements.txt

To install directly from source: git clone && cd dwolla-python && python install


dwolla-python makes it easy for developers to hit the ground running with our API. Before attempting the following, you should ideally create an application key and secret.

  • Change settings in on-the-fly by doing from dwolla import constants, constants.some_setting = some_value.
  • from dwolla import module where module is either accounts, checkouts, contacts, fundingsources, masspay, oauth, request, or transactions, or from dwolla import * to import all.

Sample Code

dwolla-python allows you to import only the modules you need.

For this example, we will get information about a Dwolla ID.

from dwolla import accounts

print accounts.basic('812-121-7199')

dwolla-python also allows you to import the entire library to access everything at once.

For this example, we will get information about a Dwolla ID, as well as request 5.00 from that same ID.

from dwolla import *

# Get information about the ID

print accounts.basic('812-121-7199')

# Request $5.00 from that ID

print request.create('812-121-7199', 5.00)

Configuration and Use

Whenever you change settings, they will only be partially applied. This means that settings in will remain until they are changed. You can do so on-the-fly or by editing the file.

Default Settings
client_id = 'YOUR ID HERE'
client_secret = 'YOUR SECRET HERE'
pin = 1234

oauth_scope = 'Send|Transactions|Balance|Request|Contacts|AccountInfoFull|Funding|ManageAccount'
access_token = 'OAUTH TOKENS GO HERE'

# Hostnames, endpoints
production_host = ''
sandbox_host = ''
default_postfix = 'oauth/rest'

# Client behavior
sandbox = True
debug = True
host = None
rest_timeout = 15
proxy = False

dwolla-python also supports proxies. In order to set proxies, you must assign a python dictionary to the proxy constant in the following format:

proxy = {
    'http': 'http://someproxy:someport',
    'https': 'https://anotherproxy:anotherport'
Changing Settings

In order to use the library, you must use your own client_id, client_secret, or access_token. It is generally recommended to modify constants as shown below, but client control flags also expose this functionality.

# Import everything from the dwolla package
from dwolla import *

# Configure the library (change these)

constants.client_id = "zbDwIC0dWCVU7cQtfvGwVwVjvxwQfjaTgkVi+FZOmKqPBzK5JG"
constants.client_secret = "ckmgwJz9h/fZ09unyXxpupCyrmAMe0bnUiMHF/0+SDaR9RHe99"
constants.access_token = "aK6DdCVlIsR1hKvTbp8VCwnvci8cwaTLlW9edtbHJVmKoopnoe"

# Example 1: Get basic information for a user via
# their Dwolla ID.

print accounts.basic('812-202-3784')

Specifying additional parameters

For the API

As of version 2.2.0, you are no longer required to pass in additional API parameters in a params={...} dictionary. You can just simply specify the name of the parameter and its value as in the example below.

Example; Fetch a user’s contacts, limit results to 5

python def get(**kwargs): “`python from dwolla import contacts

contacts.get(limit=5) “`

NOTE: If a params={...} dictionary is passed, it will be used instead of any additional **kwargs parameters. This excludes the client control flags noted in the next session. This is done to preserve function calls made to versions prior to 2.2.0. The params parameter behavior will be deprecated as of 3.x releases.

Client Control Flags

dwolla-python supports the following client control flags. They override any applicable settings in the constants module for the call which they are present in. They do not get sent to the Dwolla API and are popped out of **kwargs.

  • dwollaparse
    • Parses the API response obtained from the Dwolla API and returns data to the user.
    • Default: dwolla
    • Acceptable Values: raw (JSON-ify’d string), dict (Dictionary/Parsed JSON data), dwolla (an extension of default, where the contents of the Response key are returned and the rest disposed).
  • client_id
    • Overrides the “client_id“ set in “constants“ for the call which it is present in.
    • Acceptable Values: (any valid client_id)
  • client_secret
    • Overrides the “client_secret“ set in “constants“ for the call which it is present in.
    • Acceptable Values: (any valid client_secret)
  • alternate_token
    • Overrides the “access_token“ set in “constants“ for the call which it is present in.
    • Acceptable Values: (any valid OAuth token)
  • alternate_pin
    • Overrides the “pin“ set in “constants“ for the call which it is present in.
    • Acceptable Values: (any valid PIN)
Example; Fetch a user’s contacts, limit results to 5, provide alternate OAuth token.

python def get(**kwargs): “`python from dwolla import contacts

contacts.get(limit=5, alternate_token=”Some alternate token.”) “`

There are 9 quick-start files which will walk you through working with dwolla-python’s classes/endpoint groupings.

  • Instantiate library with custom settings.
  • Retrieve account information, such as balance.
  • Offsite-gateway endpoints, server-to-server checkout example.
  • Retrieve/sort through user contacts.
  • Modify and get information with regards to funding sources.
  • Create and retrieve jobs/data regarding MassPay jobs.
  • Examples on retrieving OAuth access/refresh token pairs.
  • Create and retrieve money requests/information regarding money requests.
  • Send money, get transaction info by ID, etc.


dwolla-python is a conglomerate of multiple modules; each module in the dwolla/ directory is named after a the endpoints that it covers (similar to Dwolla’s developer documentation).

Unit Testing

dwolla-python uses unittest for unit testing. Integration testing is planned sometime in the future.

To run the tests, install dwolla-python as per the aforementioned instructions and run:

cd location/of/the/library
pip install unittest
python -m unittest discover tests/


In order for the library’s README file to display nicely on PyPi, we must use the *.rst file format. When making changes to this README file, please use this tool to convert the *.md file to *.rst, and make sure to keep both files updated.

This wrapper is based on requests for REST capability and uses unittest for unit testing and Travis for automagical build verification.
