Swagger for Confirmation of Funds API Specification

This is the Xero Payroll API for orgs in Australia region.

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

Swagger for Payment Initiation API Specification

Portfolio Optimizer is a Web API to optimize the composition of investment portfolios (collection of financial assets such as stocks, bonds, ETFs, crypto-currencies) using modern portfolio theory-like algorithms (mean-variance, etc.).
API General Information
Portfolio Optimizer is based on REST for easy integration, uses JSON for the exchange of data and uses the two most common HTTP verbs (GET, POST) to represent the actions.
Portfolio Optimizer is also as secured as a Web API could be:
256-bit HTTPS Encryption
No usage of cookies
No usage of personal data
API Headers
The following HTTP header(s) are required when calling Portfolio Optimizer endpoints:
Content-type: application/json
This header specifies that the data provided in input to the endpoint is in JSON format
The following HTTP header(s) are optional when calling Portfolio Optimizer endpoints:
X-API-Key:
This header enables authenticated users to provide their private API key in order to benefit from higher API limits
API Key
Portfolio Optimizer is free to use, but not free to run.
In order to obtain an API key and benefit from higher API limits, a small participation to Portfolio Optimizer running costs is required.
This participation takes the form of coffee(s), with one coffee = one month of usage.
Notes:
> * Please make sure not to expose your API key publicly!
API Limits
Portfolio Optimizer comes with fairly reasonable API limits.
For anonymous users:
The API requests are restricted to a subset of all the available endpoints and/or endpoints features
The API requests are limited to 1 request per second for all the anonymous users combined, with concurrent requests rejected
The API requests are limited to 1 second of execution time
The API requests are limited to 20 assets, 100 portfolios, 500 series data points and 5 factors
For authenticated users with an API key:
The API requests have access to all the available endpoints and endpoints features
The API requests are limited to 10000 requests per 24 hour per API key, with concurrent requests queued
The API requests are limited to 2.5 seconds of execution time
The API requests are limited to 100 assets, 500 portfolios, 2500 series data points and 25 factors
> Notes:
> * It is possible to further relax the API limits, or to disable the API limits alltogether; please contact the support for more details.
> * Information on the API rate limits are provided in response messages HTTP headers x-ratelimit-*:
> * x-ratelimit-limit-second, the limit on the number of API requests per second
> * x-ratelimit-remaining-second, the number of remaining API requests in the current second
> * x-ratelimit-limit-minute, the limit on the number of API requests per minute
> * ...
API Regions
Portfolio Optimizer servers are located in Western Europe.
> Notes:
> * It is possible to deploy Portfolio Optimizer in other geographical regions, for example to improve the API latency; please contact the support for more details.
