bunq Python SDK

Introduction

Hi developers!

Welcome to the bunq Python SDK! 👨‍💻

We're very happy to introduce yet another unique product: complete banking SDKs! Now you can build even bigger and better apps and integrate them with your bank of the free! 🌈

Before you dive into this brand new SDK, please consider:

• Learning how bunq works and what objects you will work with by reading the intro to our API 🤓
• Checking out our developer portal 🙌
• Grabbing your Production API key from our developer portal or the bunq app 🗝
• Generating a Sandbox API key using our developer portal or Tinker 🗝
• Visiting our forum where you can share your creations, questions and experience 🎤

Give us your feedback, create pull requests, build your very own bunq apps and most importantly: have fun! 💪

This SDK is in beta. We cannot guarantee constant availability or stability. Thanks to your feedback we will make improvements on it.

Installation

pip install bunq_sdk --upgrade

Usage

Creating an API context

In order to start making calls with the bunq API, you must first register your API key and device, and create a session. In the SDKs, we group these actions and call it "creating an API context". The context can be created by using the following code snippet:

apiContext = ApiContext.create(ENVIRONMENT_TYPE, API_KEY, DEVICE_DESCRIPTION)
apiContext.save(API_CONTEXT_FILE_PATH)

Please note: initialising your application is a heavy task and it is recommended to do it only once per device.

apiContext = ApiContext.restore(self.API_CONTEXT_FILE_PATH)
BunqContext.loadApiContext(apiContext)

After saving the context, you can restore it at any time:

Example

See tinker/setup_context

PSD2

It is possible to create an ApiContext as PSD2 Service Provider. Although this might seem a complex task, we wrote some helper implementations to get you started. You need to create a certificate and private key to get you started. Our sandbox environment currently accepts all certificates, if these criteria are met:

• Up to 64 characters
• PISP and/or AISP used in the end.

Make sure you have your unique eIDAS certificate number and certificates ready when you want to perform these tasks on our production environment.

Creating a PSD2 context is very easy:

apiContext = ApiContext.create_for_psd2(ENVIRONMENT_TYPE, CERTIFICATE, PRIVATE_KEY, CERTIFICATE_CHAIN, DEVICE_DESCRIPTION)

Safety considerations

The file storing the context details (i.e. bunq.conf) is a key to your account. Anyone having access to it is able to perform any Public API actions with your account. Therefore, we recommend choosing a truly safe place to store it.

Making API calls

There is a class for each endpoint. Each class has functions for each supported action. These actions can be create, get, update, delete and list.

Sometimes API calls have dependencies, for instance MonetaryAccount. Making changes to a monetary account always also needs a reference to a User. These dependencies are required as arguments when performing API calls. Take a look at doc.bunq.com for the full documentation.

Creating objects

Creating objects through the API requires an ApiContext, a requestMap and identifiers of all dependencies (such as User ID required for accessing a Monetary Account). Optionally, custom headers can be passed to requests.

payment_id = Payment.create(
    amount=Amount(amount_string, self._CURRENCY_EURL),
    counterparty_alias=Pointer(self._POINTER_TYPE_EMAIL, recipient),
    description=description
)

Example

See tinker/make_payment

Reading objects

Reading objects through the API requires an ApiContext, identifiers of all dependencies (such as User ID required for accessing a Monetary Account), and the identifier of the object to read (ID or UUID) Optionally, custom headers can be passed to requests.

This type of calls always returns a model.

monetary_account = generated.MonetaryAccountBank.get(
    _MONETARY_ACCOUNT_ITEM_ID
)

Example

See tinker/list_all_payment

Updating objects

Updating objects through the API goes the same way as creating objects, except that also the object to update identifier (ID or UUID) is needed.

Card.update(
    card_id=int(card_id),
    monetary_account_current_id=int(account_id)
)

Example

See tinker/update_card

Deleting objects

Deleting objects through the API requires an ApiContext, identifiers of all dependencies (such as User ID required for accessing a Monetary Account), and the identifier of the object to delete (ID or UUID) Optionally, custom headers can be passed to requests.

Session.delete(self._SESSION_ID)

Example

Listing objects

Listing objects through the API requires an ApiContext and identifiers of all dependencies (such as User ID required for accessing a Monetary Account). Optionally, custom headers can be passed to requests.

users = User.list(api_context)

Example

See UserListExample.py

Running Samples

To get an indication on how the SDK works you can use the python tinker which is located at https://github.com/bunq/tinker_python

Running Tests

Information regarding the test cases can be found in the README.md located in test.

Exceptions

The SDK can raise multiple exceptions. For an overview of these exceptions please take a look at EXCEPTIONS.md.
