Configuring API Manager

WSO2 Open Banking CDS Toolkit contains TOML-based configurations. All the server-level configurations of the API Manager instance can be applied using a single configuration file, which is the deployment.toml file.

Configuring deployment.toml

Follow the steps below to configure the deployment.toml file and set up the open banking flow for WSO2 API Manager.

  1. Replace the deployment.toml file as explained in the Setting up the servers section.

  2. Open the <APIM_HOME>/repository/conf/deployment.toml file.

  3. Set the hostname of the API Manager:

    [server]
hostname = "<APIM_HOST>"

  4. Update the datasource configurations with your database properties, such as the username, password, JDBC URL for the database server, and the JDBC driver.

    • Given below are sample configurations for a MySQL database. For other DBMS types and more information, see Setting up databases.
    [database.shared_db]
url = "jdbc:mysql://localhost:3306/openbank_govdb?autoReconnect=true&amp;useSSL=false"
username = "root"
password = "root"
driver = "com.mysql.jdbc.Driver"
    [database.apim_db]
url = "jdbc:mysql://localhost:3306/openbank_apimgtdb?autoReconnect=true&amp;useSSL=false"
username = "root"
password = "root"
driver = "com.mysql.jdbc.Driver"
    [database.config]
url = "jdbc:mysql://localhost:3306/openbank_am_configdb?autoReconnect=true&amp;useSSL=false"
username = "root"
password = "root"
driver = "com.mysql.jdbc.Driver"
    [[datasource]]
id="WSO2UM_DB"
url = "jdbc:mysql://localhost:3306/openbank_userdb?autoReconnect=true&amp;useSSL=false"
username = "root"
password = "root"
driver = "com.mysql.jdbc.Driver"

  5. Update the following configurations with the hostname of the Identity Server. 

    [apim.key_manager]
service_url = "https://<IS_HOST>:9446${carbon.context}services/"
    [apim.key_manager.configuration]
ServerURL = "https://<IS_HOST>:9446${carbon.context}services/"
    [open_banking.dcr]
jwks_endpoint_name = "jwks_uri"
app_name_claim = "client_name"
token_endpoint = https://<APIM_HOST>:9443/oauth2/token

  6. Add the following and configure the hostname of the Identity Server. 

    [open_banking.gateway]
consent.validation.endpoint = "https://<IS_HOST>:9446/api/openbanking/consent/validate"

  7. Add the following gateway executor configurations for the Consent flow:

    [[open_banking.gateway.openbanking_gateway_executors.type]]
name = "Consent"
[[open_banking.gateway.openbanking_gateway_executors.type.executors]]
name = "com.wso2.openbanking.accelerator.gateway.executor.impl.selfcare.portal.UserPermissionValidationExecutor"
priority = 1

  8. Configure holder_identifier with the Data Holder specific identifier.

    [open_banking_cds.headers]
holder_identifier="HolderIdentifierValue"

  9. Configure the encryption/decryption key for ID permanence. By default, the secret value is wso2.

    [open_banking_cds.id_permanence]
enabled=true
secret_key="wso2"

  10. Configure the endpoints to retrieve sharable and payable accounts. This is required when displaying the accounts on the consent page.

    [open_banking_cds.consent_management]
sharable_account_retrieval_endpoint = "http://<APIM_HOST>:9763/api/openbanking/cds/backend/services/bankaccounts/bankaccountservice/sharable-accounts"

  11. To generate the self link in the consent JSON response, configure the URLs of the exposed APIs as follows:

    [open_banking_cds.consent]
account_consent_self_link = "https://<APIM_HOST>:8243/cds-au/{version}/banking/accounts"

  12. Enable Request-URI validation that validates AccountID in the request against the AccountID in consent during account retrieval. By default, this is disabled and the configuration is set to false.

    [open_banking_cds.consent]
Validate_acc_id_on_retrieval_enabled = true

  13. If you want to use the Data publishing feature:

    • Enable the feature and configure the server_url property with the hostname of WSO2 Streaming Integrator.
    [open_banking.data_publishing]  
enable = true   
username="$ref{super_admin.username}@carbon.super"  
password="$ref{super_admin.password}"   
server_url = "{tcp://<SI_HOST>:7612}"

  14. To enable the Consent Amendment History feature, add the following configurations and the event executor:

    [open_banking.consent.amendment_history]
enabled=true
    [[open_banking.event.event_executors]]
name = "com.wso2.openbanking.cds.consent.extensions.event.executor.CDSConsentEventExecutor"
priority = 1
[[open_banking.event.event_executors]]
name = "com.wso2.openbanking.accelerator.consent.extensions.event.executors.ConsentAmendmentHistoryEventExecutor"
priority = 2

Starting servers

  1. Go to the <APIM_HOME>/bin directory using a terminal.

  2. Run the wso2server.sh script as follows:

    ./api-manager.sh

Configure Identity Server as Key Manager

  1. Sign in to the Admin Portal of API Manager at https://<APIM_HOST>:9443/admin.
  2. Go to Key Manager on the left main menu. add_Key_Manager

  3. Click Add New Key Manager and configure Key Manager.
