Summary
The Swiss NextGen API is based on the NextGenPSD2 Framework Version 1.3.4 of the Berlin Group which offers a modern, open, harmonised and interoperable set of
Application Programming Interfaces (APIs) as the safest and most efficient way to provide data securely.
The NextGen Framework reduces XS2A complexity and costs, addresses the problem of multiple competing standards
in Europe and, aligned with the goals of the Euro Retail Payments Board,
enables European banking customers to benefit from innovative products and services ('Banking as a Service')
by granting TPPs safe and secure (authenticated and authorised) access to their bank accounts and financial data.
The Swiss edtion refines the message formats specific to Switzerland and defines some matching examples.
The possible Approaches are:
Redirect SCA Approach
(Not recommended by obp.ch community) OAuth SCA Approach
(Not recommended by obp.ch community) Decoupled SCA Approach
(Not recommended by obp.ch community) Embedded SCA Approach without SCA method
(Not recommended by obp.ch community) Embedded SCA Approach with only one SCA method available
(Not recommended by obp.ch community) Embedded SCA Approach with Selection of a SCA method
Not every message defined in this API definition is necessary for all approaches.
Furthermore this API definition does not differ between methods which are mandatory, conditional, or optional
Therefore for a particular implementation of a compliant API it is only necessary to support
a certain subset of the methods defined in this API definition.
**Please have a look at the implementation guidelines if you are not sure
which message has to be used for the approach you are going to use.**
Some General Remarks Related to this version of the OpenAPI Specification:
This API definition is based on the Implementation Guidelines of the Berlin Group API.
It is not a replacement in any sense.
The main specification is (at the moment) always the Implementation Guidelines of the Berlin Group API.
This API definition contains the REST-API for requests from the PISP to the ASPSP.
This API definition contains the messages for all different approaches defined in the Implementation Guidelines.
According to the OpenAPI-Specification [https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.1.md]
"If in is "header" and the name field is "Accept", "Content-Type" or "Authorization", the parameter definition SHALL be ignored."
The element "Accept" will not be defined in this file at any place.
The elements "Content-Type" and "Authorization" are implicitly defined by the OpenApi tags "content" and "security".
There are several predefined types which might occur in payment initiation messages,
but are not used in the standard JSON messages in the Implementation Guidelines.
Therefore they are not used in the corresponding messages in this file either.
We added them for the convenience of the user.
If there is a payment product, which needs these fields, one can easily use the predefined types.
But the ASPSP need not to accept them in general.
**We omit the definition of all standard HTTP header elements (mandatory/optional/conditional)
except they are mentioned in the Implementation Guidelines.**
Therefore the implementer might add these in his own realisation of a comlient API in addition to the elements defined in this file.
General Remarks on Data Types
The Berlin Group definition of UTF-8 strings in context of the API have to support at least the following characters
a b c d e f g h i j k l m n o p q r s t u v w x y z
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
0 1 2 3 4 5 6 7 8 9
/ - ? : ( ) . , ' +

The Assets API exposes fixed asset related functions of the Xero Accounting application and can be used for a variety of purposes such as creating assets, retrieving asset valuations etc.

Introduction
The Business Registries API is built on HTTP. The API is RESTful. It has predictable resource URIs.
The API is documented in OpenAPI format.
In addition to the standard OpenAPI syntax we use a few
vendor extensions.
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 format:
YYYY-MM-DD
For example: 2017-07-01 (the 1st of July 2017)
All timestamps use the 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 header.
For example:
Link:; rel="next",; 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.
