An official requests based wrapper for the Dwolla API

Project description

dwolla-python
=============

Official Python wrapper for Dwolla’s API

Version
-------

1.6.6

Requirements
------------

- `Python`_
- `Dwolla Application`_

Installation
------------

Automatic installation using `pip`_:

::

pip install dwolla

Usage
-----

.. code:: python

from dwolla import DwollaUser
DwollaUser = DwollaUser('[OAuth Token Goes Here]')

transactionId = DwollaUser.send_funds(1.00, '812-626-8794', '[PIN]')
print transactionId

Examples / Quickstart
---------------------

To use the examples in the /examples folder, first edit the \_keys.py
file and add your Dwolla API application’s key, and secret, along with
your account’s `OAuth token`_, and PIN.

This repo includes various usage examples, including:

- Authenticating with OAuth [oauth.py]
- Sending money [send.py]
- Fetching account information [accountInfo.py]
- Grabbing a user’s contacts [contacts.py]
- Listing a user’s funding sources [fundingSources.py]
- Creating offsite gateway sessions [offsiteGateway.py]
- Registering a new Dwolla user account [registerUser.py]
- Handling money requests [request.py]

Environment Variables
---------------------

- ``DWOLLA_VERIFY_SSL`` (optional; True/False) Should we verify
Dwolla’s SSL?
- ``DWOLLA_DEBUG`` (optional; True/False) Enable verbose debug?
- ``DWOLLA_SANDBOX`` (optional; True/False) Use Dwolla’s UAT env?
- ``DWOLLA_API_HOST`` (optional; String/URL) A custom API host URL;
defaults to https://www.dwolla.com/

Instantiation Variables
-----------------------

If an application makes it difficult to use environment variables to set
parameters, each of the aforementioned variables can be put into a
Python ``dict`` upon instantiation of ``DwollaGateway()``,
``DwollaClientApp()``, and ``DwollaUser()``.

.. code:: python

{
'VERIFY_SSL': True,
'DEBUG': True,
'SANDBOX': True,
'HOST': 'https://somecustomhost.thatyouprobablywontset.dwolla.com'
}

Let’s take the previous example from the Usage section, and make our
requests target the UAT environment via instantiation variables:

.. code:: python

from dwolla import DwollaUser
DwollaUser = DwollaUser('[OAuth Token Goes Here]', {'SANDBOX': True})

transactionId = DwollaUser.send_funds(1.00, '812-626-8794', '[PIN]')
print transactionId

Methods
-------

DwollaClientApp class:

::

init_oauth_url(redircet_uri, scope) ==> (string) OAuth permissions page URL
get_oauth_token(code) ==> (string) a never-expiring OAuth access token
get_account_info(account_id) ==> (array) the user entity for {account_id}
get_nearby_spots([lat, lon, range, limit]) ==> (array) list of nearby spots matching the search criteria
register_user(email, password, pin, firstName, lastName, address, address2, city, state, zip, phone, dateOfBirth[, organization, ein, type, acceptTerms]) ==> (dict) the newly created user record

DwollaUser class:

::

get_balance() ==> (string) the Dwolla balance of the account associated with the token
get_account_info(account_id) ==> (dict) the user entity associated with the token
get_nearby_users(lat, lon)
get_contacts([search, types, limit]) ==> (array) list of contacts matching the search criteria

get_transaction(transaction_id) ==> (dict) transaction details
get_transaction_list([since, types, limit, skip]) ==> (array) a list of recent transactions matching the search criteria
get_transaction_stats([types, start_date, end_date]) ==> (dict) statistics about the account associated with the token
send_funds(amount, dest, pin[, notes, assume_cost, facil_amount, dest_type]) ==> (string) transaction ID

request_funds(amount, source, pin[, notes, facil_amount, source_type]) ==> (string) request ID
fulfill_request(request_id, pin[, amount, notes, funds_source, assume_cost])
cancel_request(request_id)
get_request(request_id)
get_pending_requests()

get_funding_sources() ==> (array) a list of funding sources associated with the token
get_funding_source(id) ==> (dict) information about the {id} funding source
add_funding_source(routing_number, account_number, account_type, account_name)
verify_funding_source(source_id, deposit1, deposit2)
withdraw(source_id, pin, amount)
deposit(source_id, pin, amount)

DwollaGateway class:

::

set_mode(mode) ==> (bool) did mode change?
start_gateway_session() ==> (bool) did session start?
add_gateway_product(name, amount[, desc, qty]) ==> (bool) was product added?
verify_gateway_signature(signature, checkout_id, amount) ==> (bool) is signature valid?
get_gateway_URL(destination_id[, order_id, discount, shipping, tax, notes, callback]) ==> (string) checkout URL
