This API provides endpoints for managing your point-of-sale (POS) payment terminals. You can use the API to obtain information about a specific terminal, retrieve overviews of your terminals and stores, and assign terminals to a merchant account or store. For more information, refer to Assign terminals. ## Authentication Each request to the Terminal Management API must be signed with an API key. For this, obtain an API Key from your Customer Area, as described in How to get the API key. Then set this key to the `X-API-Key` header value, for example: ``` curl -H "Content-Type: application/json" \ -H "X-API-Key: Your_API_key" \ ... ``` Note that when going live, you need to generate new web service user credentials to access the live endpoints. ## Versioning Terminal Management API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number. For example: ``` https://postfmapi-test.adyen.com/postfmapi/terminal/v1/getTerminalsUnderAccount ``` When using versioned endpoints, Boolean response values are returned in string format: `"true"` or `"false"`. If you omit the version from the endpoint URL, Boolean re

# Introduction The Rebilly API is built on HTTP. Our API is RESTful. It has predictable resource URLs. It returns HTTP response codes to indicate errors. It also accepts and returns JSON in the HTTP body. You can use your favorite HTTP/REST library for your programming language to use Rebilly's API, or you can use one of our SDKs (currently available in PHP and Javascript). We have other APIs that are also available. Every action from our app is supported by an API which is documented and available for use so that you may automate any workflows necessary. This document contains the most commonly integrated resources. # Authentication When you sign up for an account, you are given your first secret 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 Rebilly API by providing your secret key in the request header. Rebilly offers three forms of authentication: secret key, publishable key, JSON Web Tokens, and public signature key. - Secret API key: used for requests made from the server side. Never share these keys. Keep them guarded and secure. - Publishable API key: used for requests from the

# 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) Embedd
