bunq API

***UPDATE:*** *We have released a [beta version of the new bunq API documentation.](https://beta.doc.bunq.com)* ***NOTICE:*** *We have updated the sandbox base url to `https://public-api.sandbox.bunq.com/v1/`. Please update your applications accordingly. Check here: <https://github.com/bunq/sdk_php/issues/149> for more info.* ***PSD2 NOTICE:*** *The second Payment Services Directive (PSD2) may affect your current or planned usage of our public API, as some of the API services are now subject to a permit. Please be aware that using our public API without the required PSD2 permit is at your own risk and take notice of our updated API Terms and Conditions on <https://www.bunq.com> for more information.* # Introduction Welcome to bunq! - The bunq API is organised around REST. JSON will be returned in almost all responses from the API, including errors but excluding binary (image) files. - Please configure your implementation to send its API requests to `https://public-api.sandbox.bunq.com/v1/` - There is a version of the [Android app](https://appstore.bunq.com/api/android/builds/bunq-android-sandbox-master.apk) that connects to the bunq Sandbox environment. To create accounts for the Sandbox app, please follow the steps in the [Android Emulator](#android-emulator) section. ## Getting started Before you start sending API requests, you need to get an API key and activate it. API activation happens when you install the API key and link your IP address and device to it *(create an API context)*. The steps below will guide you through what you need to do to start sending custom API requests. Here is an overview of what you can use to get started with the bunq API: 1. **Create an API key.** You can do it either in our [developer portal](https://developer.bunq.com) or in the bunq app *(Profile → Security & Settings → Developers → API keys)*. If you want to test our sandbox first, our [bunq Developer ](https://developer.bunq.com)is the best place to start. 2. **Register a device.** A device can be a phone (private), computer or a server (public). You can register a new device by using the `POST /installation` and `POST /device-server` calls. This will activate your API key. You only need to do this once. 3. **Open a session.** Sessions are temporary and expire after the auto-logout time set for the user account. It can be changed by the account owner in the bunq app. 4. **Make your first call!** ![bunq_API_context](https://www.bunq.com/assets/media/developer/API-context.jpg) ## Versioning Developments in the financial sector, changing regulatory regimes and new feature requests require us to be flexible. This means we can iterate quickly to improve the API and related tooling. Therefore, we have chosen not to attach any version numbers to the changes just yet. We will inform you in a timely manner of any important changes we make before they are deployed on together.bunq.com. You can also [subscribe to our API newsletter](https://bunq.us8.list-manage.com/subscribe?u=c00d0d6daea4e1cf7c863d52e&id=b08680cdc7) to make sure you don't miss any important updates. # OAuth ## What is OAuth? [OAuth 2.0](https://www.oauth.com/oauth2-servers/getting-ready/) is a protocol that will let your app connect to bunq users in a safe and easy way. Please be aware that if you will gain access to the account information of other bunq users or initiate a payment for them, [you may require a PSD2 permit](https://beta.doc.bunq.com/other/faq#can-we-use-the-bunq-api-to-offer-services-to-third-parties). ## Get started with OAuth for bunq To initiate authorization into the bunq user accounts, you need to create an OAuth Client and register at least 1 redirect URL for it. You can have 1 OAuth Client at a

Business Registries

Finance

# Introduction The Business Registries API is built on HTTP. The API is RESTful. It has predictable resource URIs. The API is documented in <a target="_blank" href="https://github.com/OAI/OpenAPI-Specification">OpenAPI</a> format. In addition to the standard OpenAPI syntax we use a few <a target="_blank" href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md">vendor extensions</a>. # Overview The following sections describe the resources that make up the Business Registries REST API. ## Current Version By default, all requests to https://api.abr.ato.gov.au receive the `v1` version of the REST API. We encourage you to explicitly request this version via the `Accept` header. Accept: application/vnd.abr-ato.v1+json ## Schema All API access is over HTTPS, and accessed from https://api.abr.ato.gov.au. All data is sent and received as JSON. Blank fields are included. All dates use the [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format: YYYY-MM-DD For example: `2017-07-01` (the 1st of July 2017) All timestamps use the [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format: YYYY-MM-DDTHH:MM:SSZ For example: `2017-07-01T11:05:06+10:00` ## Timezones Some requests allow for specifying timestamps or generate timestamps with time zone information. We apply the following rules, in order of priority, to determine timezone information for API calls. ### Explicitly provide an ISO 8601 timestamp with timezone information For API calls that allow for a timestamp to be specified, we use that exact timestamp. For example: `2017-07-01T11:05:06+10:00` ## Pagination Information about pagination is provided in the [Link](https://tools.ietf.org/html/rfc5988#page-6) header. For example: Link: <https://api.abr.ato.gov.au/individuals?page=2>; rel="next", <https://api.abr.ato.gov.au/individuals?page=34>; rel="last" `rel="next"` states that the next page is `page=2`. This makes sense, since by default, all paginated queries start at page `1`. `rel="last"` provides some more information, stating that the last page of results is on `page 34`. Accordingly, we have 33 more pages of information that we can consume. ## Parameters Many API methods take optional parameters: GET /individuals/1234/addresses/?addressType='Mailing' In this example, the '1234' value is provided for the `:partyId` parameter in the path while `:addressType` is passed in the query string. For POST, PATCH, PUT, and DELETE requests, parameters not included in the URL should be encoded as JSON with a Content-Type of 'application/json'. ## Metadata The API provides **metadata services** that you can use to discover information about the classifcation schemes and values used by the Registry. For example: GET /classifications/roles Sample response: [ { "id": "123e4567-e89b-12d3-a456-426655440001", "role": "Director", "roleDescription": "An individual responsible for managing a company's ...", "relationship": "Directorship", "reciprocalRole": "Company", "reciprocalRoleDescription": "An incorporated legal entity." }, { ... } ] ## Root Endpoint You can issue a GET request to the root endpoint (also known as the service root) to get all the endpoint categories that the REST API supports: curl https://api.abr.ato.gov.au ## Authentication The Business Registries API supports API Key authentication. When you sign up for an account, you are given your first API key. You can generate additional API keys, and delete API keys (as you may need to rotate your keys in the future). You authenticate to the Business Registries API by providing your secret key in the request header. **Note:** Some requests will return `404 Not Found`, instead of `403 Permission Denied`. This is to prevent the accidental leakage of information to unauthorised users.
