Configure open-banking.xml files in both WSO2 Open Banking Key Manager(WSO2 OB KM) and WSO2 Open Banking API Manager(WSO2 OB APIM) components based on the configurations listed below.

The open-banking.xml files are in below locations:

  • <WSO2_OB_KM_HOME>/repository/conf/finance/open-banking.xml
  • <WSO2_OB_APIM_HOME>/repository/conf/finance/open-banking.xml

Do the following configurations in both the Key Manager and API Manager components and restart the servers.


Configuration
1

Define the specification that you plan to deploy.

Possible values: UK, BERLIN, AU, STET

<DeployedSpecification>UK</DeployedSpecification> 
2

If you want to enable the event notification feature, set the <isEnabled> to true, and define the following configurations:

  • <TokenIssuer>: The URL from where the token is issued.
  • <NotificationExpiryTime>: The expiry time of the notification, in seconds.
  • <NotificationAPIUrl>: The URL of the event-notification endpoint which is exposed from API Manager.
  • <NumberOfSetsToReturn>: The maxEvents parameter in the polling request informs the ASPSP how many notifications the TPP wants to retrieve at a moment. When the maxEvents parameter is absent in the polling request,  NumberOfSetsToReturn defines this value.
  •  <SigningAlias>: The alias of the certificate that signs the notifications sent from ASPSP to TPP.  
<EventNotifications>
	<IsEnabled>false</IsEnabled>
	<TokenIssuer>www.openbank.com</TokenIssuer>
	<NotificationExpiryTime>180</NotificationExpiryTime>
	<NotificationAPIUrl>https://<WSO2_OB_APIM_HOST>:8243/open-banking/v3.1/event-notification</NotificationAPIUrl>
	<NumberOfSetsToReturn>5</NumberOfSetsToReturn>
	<SigningAlias>1</SigningAlias>
</EventNotifications>
3

To log the Consent Management API calls in JSON format:

  1. Set the LogConsentInformation configuration to true in <WSO2_OB_KM_HOME>/repository/conf/finance/open-banking.xml.

    <LogConsentInformation>true</LogConsentInformation>
  2. Add the following properties to the <WSO2_OB_KM_HOME>/repository/conf/log4j.properties file. 
    This is to save the log entries in the <WSO2_OB_KM_HOME>/repository/logs/transaction.log file in JSON format.

    log4j.logger.TRANSACTION_LOGGER=INFO, TRANSACTION_LOGGER
    log4j.appender.TRANSACTION_LOGGER=org.apache.log4j.FileAppender
    log4j.appender.TRANSACTION_LOGGER.File=${carbon.home}/repository/logs/transaction.log
    log4j.appender.TRANSACTION_LOGGER.Append=true
    log4j.appender.TRANSACTION_LOGGER.layout=org.apache.log4j.PatternLayout
    log4j.appender.TRANSACTION_LOGGER.layout.ConversionPattern=[%d] - %m %n
    log4j.appender.TRANSACTION_LOGGER.threshold=INFO
    log4j.additivity.TRANSACTION_LOGGER=false

<DaysToExpireRequest>: Defines the number of days after which the system considers the consent as expired if the required authorisation is not given.

<MultiAuthorization>
  <DaysToExpireRequest>3</DaysToExpireRequest>
</MultiAuthorization>
5
  • Shareable accounts - accounts that are accessible online.

<SharableAccountsRetreiveEndpoint>: Configures the endpoint to retrieve sharable accounts that required to list on the consent page.

<SharableAccountsRetrieveEndpoint>http://<WSO2_OB_APIM_HOST>:9763/open-banking/services/bankaccounts/bankaccountservice/sharable-accounts</SharableAccountsRetreiveEndpoint>
  • Payable accounts - accounts from which a PSU can make a payment.

<PayableAccountsRetrieveEndpoint>: Configures the endpoint to retrieve payable accounts that required to list on the consent page.

<PayableAccountsRetrieveEndpoint>http://<WSO2_OB_APIM_HOST>:9763/open-banking/services/bankaccounts/bankaccountservice/payable-accounts</PayableAccountsRetrieveEndpoint>

In some banks, some PSUs may have a certain number of accounts, but not all accounts have the ability to be shared externally or to make a payment online. In a bank, the shareable account list and the payable account list can either be the same or different.

In the default WSO2 Open Banking solution, at least two APIs are expected to return shareable and payable accounts when passing the user_id, and the given JSON response must be returned. Then it automatically loads the accounts list in the consent page.

{
 "data": [
  {
   "account_id": "1234-2345-3456-4567",
   "display_name": "1234-2345-3456-4567"
  },
  {
   "account_id": "9999-4345-8456-4567",
   "display_name": "9999-4345-8456-4567"
  }
 ]
}

By default, mock backend deployed in WSO2_OB_APIM is configured. Required parameters can be passed as query parameters to those endpoints. An example of configuring the endpoint to retrieve payable accounts:

http://<WSO2_OB_APIM_HOST>:9443/as400/payable-accounts/{userId}

If you plan to implement the multi-authorization feature for the PISP flow, the payable account retrieval endpoint should return the following JSON response.

{
 "data": [{
   "account_id": "30080098971337",
   "display_name": "30080098971337",
   "authorizationMethod": "multiple",
   "authorizationUsers": [{
     "customer_id": "123",
     "user_id": "[email protected]@carbon.super"
    },
    {
     "customer_id": "456",
     "user_id": "[email protected]@carbon.super"
    }
   ]
  }
 ]
}


An example of configuring the endpoint to retrieve sharable accounts:

http://<WSO2_OB_APIM_HOST>:9443/as400/sharable-accounts/{userId}

Enable Request-URI validation:

During account retrieval to validate AccountID against the AccountID in consent, add the following configurations under the <UK> element:

<!-- Validate AccountID with consented accountID in account retrieval -->
<ValidateAccountIdOnRetrieval>true</ValidateAccountIdOnRetrieval>
7

Configure the role to identify the customer care officers, who are able to access the customer care portal, and revoke the consents on behalf of customers.

<UK>          
  <CustomerCareOfficerRole>Internal/CustomerCareOfficer</CustomerCareOfficerRole>
</UK>
8

The unique ID of the ASPSP to which the request is issued. The unique ID is issued by OBIE and corresponds to the Organization ID of the ASPSP in the Open Banking Directory. If the value does not match the expected value (based on the Client ID or network certificate of the caller), the ASPSP must reject the request with a 403 (Not Authorized) status code.

<UK>
  <XFAPIFinancialId>open-bank</XFAPIFinancialId>
</UK>
9

According to the openbanking.org.uk specification, the links to access the created resource must be returned, as follows.

"Links": {
   "Self": "https://api.alphabank.com/open-banking/v2.0/accounts/22289"
 },

In order to generate the self URL shown in the above JSON, configure the URLs of the exposed APIs, as shown in the below configuration.

<UK>
   <PaymentAPIURL>https://<WSO2_OB_APIM_HOST>:8243/open-banking/{version}/pisp/</PaymentAPIURL>
   <AccountAPIURL>https://<WSO2_OB_APIM_HOST>:8243/open-banking/{version}/aisp/</AccountAPIURL>
   <FundsConfirmationAPIURL>https://APIM_HOSTNAME:8243/open-banking/{version}/cbpii/</FundsConfirmationAPIURL>
   
   <!--configure the url to get details about the error-->
   <ErrorURL></ErrorURL>
</UK>
10

In order to improve the performance of the API Gateway, the consent validation responses for account information retrieval calls are cached.

  • <EnableConsentValidationCache>: Determines whether or not the consent validation cache is enabled at the API Gateway.
  • <ConsentValidationCacheExpiry>: The expiry time for the consent validation info cache, in seconds.
  • <DefaultCacheTimeout>: The time in which the cache times out, in seconds.
<UK>
  <Cache>
    <EnableConsentValidationCache>true</EnableConsentValidationCache>
    <ConsentValidationCacheExpiry>900</ConsentValidationCacheExpiry>
    <DefaultCacheTimeout>120000</DefaultCacheTimeout>
  </Cache>
</UK>
11

In the AISP flow, when the TPP invokes the account retrieval APIs, they can either use the /accounts/{consentId} or /accounts/{accountId}.

If they want to use consentId, the UseConsentIdInPath must be changed to true. By default, it works with the accountId.

<UK>
  <UseConsentIdInPath>false</UseConsentIdInPath>
</UK>
12

The following configuration is used to handle release management of the deployed API specifications.

E.g., If the resource is created using the API specification version v2.0, that resource can only be accessible using API specifications v2.0 and above.

<UK200SupportedSpecsToRequest>UK200|UK300</UK200SupportedSpecsToRequest>
<UK>
  <UK110SupportedSpecsToRequest>UK110|UK200|UK300</UK110SupportedSpecsToRequest>
  <UK200SupportedSpecsToRequest>UK200|UK300</UK200SupportedSpecsToRequest>
  <UK300SupportedSpecsToRequest>UK300</UK300SupportedSpecsToRequest>
</UK>
13

Account permissions not supported by the ASPSP can be restricted for the TPP by specifying one or more permissions separated by a pipe (|). By default, no permissions are restricted.

E.g. ReadOffers|ReadPAN|ReadParty|ReadPartyPSU

If Mutual Transport Layer Security (MTLS) is terminated before the request reaches the Gateway, retrieve the TPP's certificate from the MTLS session and include as a transport certificate header. By default, the gateway expects ssl.client.auth.cert.X509 as the transport header. Include the value for the transport certificate header in TransportCertificateHeader under CertificateManagement element. See the sample configuration below.

 <CertificateManagement>
        <!-- In order to enable the client certificate validation feature (Certificate Expiry, Signature and
        Revocation validation during MTLS), the following module needs to be engaged under the "Global Engaged
        Modules" section in the axis2.xml file.

        <module ref="mtlscertvalidator"/>
        -->

        <!--Set the value of the transport certificate header sent in the request if MTLS is terminated before the
        gateway default value is ssl.client.auth.cert.X509-->
        <TransportCertificateHeader>ssl.client.auth.cert.X509</TransportCertificateHeader>
</CertificateManagement>

The load balancer should not allow the TPP to send its certificate as a transport certificate header that is configured in the open-banking.xml under <TransportCertificateHeader> element. 

If such header was found in the TPP’s request, it is mandatory to remove that header from the TPP’s request. This is applicable even when the MTLS session is not terminated at the load balancer.

20

In order to enable certificate revocation validation for API security, make sure that the following configurations are added under the server root element.

<CertificateManagement>
	<!-- Expiry time for the cache (in seconds) for storing the validation result of the certificates-->
	<ClientCertificateCacheExpiry>3600</ClientCertificateCacheExpiry>
	<!-- Enable/Disable certificate OCSP and CRL validation. Default value has been set to true -->
	<CertificateRevocationValidationEnabled>true</CertificateRevocationValidationEnabled>
</CertificateManagement>

  2. Update the credentials under <APISecurity><Global> with the created user details.

    By default, this is set to the username and password of the super admin.

    <APISecurity>
    	<Global>
    		<Username>[email protected]</Username>
    		<Password>wso2123</Password>
    	</Global>

<CertificateManagement>
         <!--Mutual TLS Authenticator Certificate header-->
      <ClientAuthenticationHeader>x-wso2-mutual-auth-cert</ClientAuthenticationHeader>
 </CertificateManagement>
In addition to the above steps, follow the instructions described under MTLS bound access token.
