Try Local Setup

WSO2 Open Banking is a PSD2-compliant solution that provides secure mediation flow of information between Payment Service Providers (PSPs), Third Party Providers (TPPs) and Payment Service Users (PSUs). This document guides you through the configurations and troubleshooting that you need to set up the solution in your local environment. 

Prerequisites

Setting up the databases and starting the servers

In order to start the server, configure the databases in both the API Manager (APIM) and the Key Manager (KM) according to the open banking specification, as follows:

1. Open the <WSO2_OB_KM_HOME>/repository/resources/finance/scripts/startup.properties file and configure the following:

   • Specify the hostnames for the APIM and KM servers.

     # Specify the hostname you want to configure
     APIM_HOSTNAME=localhost
     IAM_HOSTNAME=localhost

   • Configure the databases related properties.

     Database Property	Description
     DB_TYPE	Type of the database you installed DB_TYPE=mysql
     DB_USER	Database user
     DB_PASS	Password set for the database connection
     DB_HOST	Name of the database server
     DB_DRIVER	Configure DB_DRIVER according to the database installed: - Mysql JDBC Driver = com.mysql.jdbc.Driver  - MSSQL JDBC Driver = com.microsoft.sqlserver.jdbc.SQLServerDriver - Oracle JDBC Driver = oracle.jdbc.driver.OracleDriver

     If you are using MSSQL or Oracle, create the following databases before executing the configure-km.sh file.

     • openbank_am_configdb   

     • openbank_apimgt_statsdb

     • openbank_apimgtdb

     • openbank_consentdb

     • openbank_govdb

     • openbank_iskm_configdb       

     • openbank_mbstoredb

     • openbank_userdb

2. Set execution permissions to the configure-km.sh file in the <WSO2_OB_KM_HOME>/repository/resources/finance/scripts and run it using the following command:

   ./configure-km.sh

   If you're setting up Open Banking for Berlin:

   Update the data type of the given field to CLOB: 

   Database	openbank_apimgtdb
   Table	AM_APPLICATION_REGISTRATION
   Field	INPUTS
   Data type	CLOB

3. Go to the <WSO2_OB_APIM_HOME>/repository/resources/finance/scripts directory and configure the database properties in the startup.properties file, similar to Step 1.

4. Set execution permissions to the configure-am.sh file and run it.

   You have configured databases in step 1. By running configure.sh files, you set the database credentials with reference to the configuration files.

5. Configure the deployed open-banking specification accordingly. 

   By default, values are set for the UK specification. Other supported specifications include:

   • UK specification - https://www.openbanking.org.uk/
   • Berlin specification - https://www.berlin-group.org/
   • STET specification - https://www.stet.eu/en/psd2/

   
   

   • The following configurations are used to define the deployed specification at runtime:

     Product	File	Config	Allowed Values
     APIM	<WSO2_OB_APIM_HOME>/repository/conf/finance/open-banking.xml	<DeployedSpecification>	UK or BERLIN or STET
     APIM	<WSO2_OB_APIM_HOME>/repository/deployment/server/jaggeryapps/store/site/conf/site.json	<DeployedSpecification>	UK or BERLIN or STET
     KM	<WSO2_OB_KM_HOME>/repository/conf/finance/open-banking.xml	<DeployedSpecification>	UK or BERLIN or STET
     KM	<WSO2_OB_KM_HOME>/repository/deployment/server/jaggeryapps/ccportal/configs/conf.json	<DeployedSpecification>	UK or BERLIN or STET
     KM	<WSO2_OB_KM_HOME>/repository/deployment/server/jaggeryapps/consentmgt/configs/conf.json	<DeployedSpecification>	UK or BERLIN or STET

6. You are now ready to start the API Manager and Key Manager servers. In the command line, navigate to the <WSO2_OB_KM_HOME> /bin folder, and run the following command:

   ./wso2server.sh -Dsetup

7. Run the same command from the <WSO2_OB_APIM_HOME>/bin directory to start the API Manager server.

Configuring users and roles

1. Sign in to the Identity and Access Management console (https://localhost:9446/carbon ). Use the default super admin credentials as follows:

   Username: admin@wso2.com

   Password: wso2123

   The above mentioned username and password credentials are used for demo purposes only. It is recommended to change the credentials in a production environment.

2. Create the necessary user roles as follows:

   • On the Main tab, click Identity > Users and Roles > Add > Add New Role.

   • Create the following user roles:

     Domain	Role	Permissions
     Internal	aispRole	No permissions required.
     Internal	pispRole	No permissions required.
     Internal	piispRole	No permissions required.
     Internal	approverRole	Admin permissions
     Internal	CustomerCareOfficer	No permissions required.

     

3. Create the necessary user accounts as follows:

   • On the Main tab, click Identity > Users and Roles > Add > Add New User.

     

   • Create the following users:

     User	Roles

Configuring a consent management application

A consent management application is configured in order to manage a consent granted to an ASPSP. After successful configurations, you can try out the Customer Care Portal. 

1. On the Main tab of the Identity and Access Management Console, click Home > Identity > Service Providers> Add.
2. Enter consentmgt as the Service Provider’s name. 
   
3. Click Register.
4. Click Inbound Authentication configuration > OAuth/OpenID Connect configuration > Configure.
   

5. Set the values for the following parameters and keep the default value for the other parameters.

   Parameter	Value
   OAuth Version	2.0
   Allowed Grant Type	code
   Callback URL	regexp=(https://localhost:9446/consentmgt|https://localhost:9446/consentmgt) The first and second URLs are respectively redirected and logout URLs.

   Regex-based consumer URLs are supported when defining the callback URL. This enables you to configure multiple callback URLs for one application by entering a regex pattern as the value for the callback URL field.

   You must have the prefix regexp= before your regex pattern. To define a normal URL, you can specify the callback URL without this prefix.

   
   

   

   The OAuth client key/client ID and OAuth client secret are generated. Those are used in Configuring consent management jaggery application.

6. Open the  wso2-obkm-version/repository/deployment/server/jaggeryapps/consentmgt/configs/conf.json  file. Modify the apimHost, applicationId, authCredential, redirectUrl, and logoutUrl parameters as follows. 

   In authCredential, be sure to encode the CLIENT_ID:CLIENT_SECRET with BASE64ENCODE encoding. 

   {
   	"app" : "consentmgt",
   	"applicationType" : "oauth2",
   	"tenantDomain": "carbon.super",
   	"apimHost":"http://localhost",
   	"apimNioPort":"8280",
   	"apimHttpPort":"9763",
   	"kmHost" : "https://localhost",
   	"kmPort" : "9446",
   	"kmTokenAPI" : "oauth2/token",
   	"kmAuthorizeAPI" : "oauth2/authorize",
   	"applicationId":"<CLIENT_ID>",
   	"authCredential":"<BASE64ENCODED CLIENT CREDENTIALS>",
   	"redirectUrl":"https://localhost:9446/consentmgt",
   	"logoutUrl": "https://localhost:9446/consentmgt",
   	"tokenApiName" : "token",
   	"tokenApiVersion" : "",
   	"authorizeApiName" : "authorize",
   	"authorizeApiVersion" : "",
   	"pagination" : {
   		"limit" : 11,
   		"actualLimit" : 10,
   		"offset": 0
   	},
   	"DeployedSpecification" : "UK"
   }

   Important

   Update the specification under DeployedSpecification parameter appropriately. Possible values are UK, BERLIN, and STET. By default, the value is set to UK.

7. Enter https://localhost:9446/ccportal URL on a web browser to access the Customer Care portal.
