An - dare I say it - awesome Python library that smartly wraps Monzo public API and allows you to use it directly in your Python project.

It creates a layer of abstraction and returns Python objects instead of just passing the received JSONs. It also deals with authentication and allows using either an access token or fully authenticate via OAuth 2 that’s a PITA to set up but is then automatically refreshed in the background.

Installation

>From PyPI:

$ pip install pymonzo

Authentication

Access token

If you want to just play around then you can simply get the access token taken from Monzo API Playground, either pass it explicitly to MonzoAPI() class or save it as an environment variable ($ export MONZO_ACCESS_TOKEN='...') and you’re good to go. Everything works as expected but the token is valid only for couple of hours.

OAuth 2

The second authentication option is to go through OAuth 2, which doesn’t sound bad (everyone is using it!) but from my experience is a PITA when setting up for server side applications. So.

Some technical background: Monzo currently only allows OAuth 2 ‘authorization code’ grant type and automatic token refreshing is only allowed for ‘confidential’ clients.

First, you need to create said client here. Name and logo don’t really matter but you need to set the redirect URL to this repo (https://github.com/pawelad/pymonzo) and set it to be confidential.

Got it? Cool. You now have required ‘Client ID’ and ‘Client secret’ and only need the auth code. You get it by creating a link with your client ID:

https://auth.getmondo.co.uk/?client_id=$ClientID&response_type=code&redirect_uri=https://github.com/pawelad/pymonzo

You then go to the link and authorise the app. You should get an email with a link back to the GitHub repo and the authorization code, something like:

https://github.com/pawelad/pymonzo?code=$AuthCode

You now have all three needed values - client ID, client secret and the auth code. As with the access token, you can either pass them directly to MonzoAPI() class or save them as environment variables:

$ export MONZO_CLIENT_ID='...'
$ export MONZO_CLIENT_SECRET='...'
$ export MONZO_AUTH_CODE='...'

That’s it! The token is then saved (~/.pymonzo) on the disk and is automatically refreshed when needed via the awesome requests-oauthlib so all this should be one time only.

Roadmap

The library currently does not implement feed items, webhooks and attachments endpoints - I plan to add them in the future, but they were’t essential to my current needs and they could be completely different in the future - per docs: > The Monzo API is under active development. Breaking changes should be expected.

I plan to implement all API functionality as soon as it comes out of beta and stabilizes.

API

There’s no documentation as of now, but the code is commented and should be pretty straightforward to use.

But feel free to ask me via email or GitHub issues if anything is unclear.

Tests

Package was tested with the help of py.test and tox on Python 2.7, 3.4, 3.5 and 3.6 (see tox.ini).

Code coverage is available at Coveralls.

To run tests yourself you need to set environment variables with access token before running tox inside the repository:

$ pip install -r requirements/dev.txt
$ export MONZO_ACCESS_TOKEN='...'
$ tox
