3. Instructions for testing APIs with enabled advanced security features (OAuth2, SCA) 

This information is relevant for PSD2 API products only.

By definition certain crucial PSD2 APIs require OAuth2. These are marked accordingly in our API documentation and swagger definitions. Here are some examples:

- consent APIs (all within PSD2 Account Information product)

- payment APIs (e.g. payment initiation request) 

On top of that, these APIs in principle (when there is no exemption defined by business rules) also require an SCA (strong customer authentication) post step. 

3.1 OAuth2

We are using the authorization code flow. As a first step you need to open the GET /oauth2/authorize link in a browser with the URL parameters response_type, client_id, redirect_uri and scope.

Possible values for scope are: 

- for Account Information: psd2:acc+iban:SI56XXXXXXXXXXXXXXX

- for Payment Initiation: psd2:pay+iban:SI56XXXXXXXXXXXXXXX

Please mind scope used in this sandbox differs from scope that should be used in production environment. Check production swagger for more information as to production values.



Of course you need to use your own i.e. you subscribed applications client_id and redirect URI. You can also achieve this redirect by selecting the "Authorize" button in the documentation of the protected API. As the authorization page opens, enter any username and password combination and select "Allow Access" on the second page. This will send you to the redirect URI with a newly generated access code as an URL parameter. You need to extract this code from this URL to get the token. To exchange the access code for the token you need some tool that can do a simple POST request, for example curl. You need to pass grant_type, client_id and code as x-www-form-urlencoded data. Here is an example:

curl -d "grant_type=authorization_code&client_id=dbe...&code=AAL7lhdq6k..." -H "Content-Type: application/x-www-form-urlencoded" -H "accept:application/json" -X POST

This will return a JSON object with the token, which you can then use to call the OAuth2 protected APIs (insert the token value prefixed with "Bearer " in the "authorization" header field) or simply paste it in the "Acces token" field in the developer portal and call the API this way. For details (URLs , parameters etc.) please also see the published swagger documents. 

3.2 SCA (Strong Customer Authentication)

According to PSD2 Berlin Group standard a SCA step is required after certain crucial i.e. sensitive API calls. We are using an implicit flow with a simple redirect (not OAuth2) for this purpose. Please check the API response header for ASPSP/PISP-SCA-Approach value and when present send i.e. redirect the end user to the URL provided in the _links/scaRedirect response element. There is no direct return of information from this redirect to your app, but certain crucial calls are made in the background to complete the authorization and process the payment or create a consent object. In our sandbox environment you can even omit this step, but for production APIs it is critical for the client to be redirected to the SCA link (when provided) if you wish the entire API flow to complete as intended. You are able to check the outcome of SCA with corresponding .../status API calls (for their details please see the API documentation i.e. swagger definition) from your application. 


4. Using Simulation plan for TPPs

We offer a simulation bank for registered TPPs. The simulation bank can be accessed by subscribing to a simulation plan (seen under the plans for each production PSD2 API).

When you subscribe, you must use a separate test application for the simulation bank. When you use the simulation plan, no real transactions are performed.

To get tokens and perform SCA, please use the link:
