Before you begin:

According to the OBIE, the Account Servicing Payment Service Providers (ASPSPs) need to make sure that the TPPs can be registered in a seamless and ideally, a fully automated process. In order to avoid any obstacles that may occur, the OBIE requires the ASPSPs to provide the TPP responses real-time once the registration is processed. The Dynamic Client Registration (DCR) endpoint is capable of dynamically registering the clients with the ASPSP when the client sends a registration request with its metadata. This results in a registration response that includes a client identifier and the client metadata values registered for the client.

You can find the REST API documentation for Dynamic Client Registration v3.2 here.


This document explains how to utilize Dynamic Client Registration with WSO2 Open Banking.  


Before you begin

  1. Run the DCR related database scripts in the <WSO2_OB_APIM_HOME>/dbscripts/dynamic-client-registration directory following Configuring Databases.
  2. Deploy the Dynamic Client Registration v3.2 API.

Configuring dynamic client registration

Follow the steps below to configure DCR API v3.2 in WSO2 Open Banking.

Uploading certificate to the client trust store

The ASPSP can upload the OB root and issuer certificates found in the below mentioned locations to the client trust store of both WSO2 API Manager (WSO2 OB APIM) and Key Manager (WSO2 OB KM).

The client trust stores are located in the WSO2 OB APIM and WSO2 OB KM servers in the following locations respectively:

  • <WSO2_OB_APIM>/repository/resources/security/client-truststore.jks
  • <WSO2_OB_KM>/repository/resources/security/client-truststore.jks

Use the following commands to add the certificate to the client trust store:

Add root certificate
keytool -import -alias tpproot -file <OB_ROOT_CERT> -keystore client-truststore.jks -storepass wso2carbo
Add issuer certificate
keytool -import -alias tppissuer -file <OB_ISSUING_CERT> -keystore client-truststore.jks -storepass wso2carbon

Updating open-banking.xml

Open the <WSO2_OB_APIM_HOME>/repository/conf/finance/open-banking.xml file. 

Add the <UseSoftwareIdAsApplicationName> property under the <DCR> tag and set it to true. 

Setting this property to true ensures that the SoftwareId in Software Statement Assertion is used as the application name.

<DCR>
	<UseSoftwareIdAsApplicationName>true</UseSoftwareIdAsApplicationName>
</DCR>

Updating api-manager.xml

To store any properties retrieved from the SSA, add the server-level configuration to the <OB_APIM_HOME>/repository/conf/api-manager.xml file as explained here . Ideally,  place the following ApplicationConfiguration at the end of the file within the APIManager element. 

For example, if you want to store software_client_id retrieved from the SSA created in the sandbox environment, the property name should look like: software_client_id_sandbox. Similarly, to store the software_client_id retrieved from the SSA created in a production environment, the property name should be: software_client_id_production. Make sure you add these properties as false, as required.

In addition to these, include software_jwks_endpoint in the SSA. This is required to obtain an access token for the application.

<ApplicationConfiguration>
	<ApplicationAttributes>
		<Attribute required="false">
			<Name>software_id_sandbox</Name>
			<Description>Software ID of the sandbox</Description>
		</Attribute>
		<Attribute required="false">
			<Name>software_id_production</Name>
			<Description>Software ID of the production</Description>

		</Attribute>
		<Attribute required="false">
			<Name>software_jwks_endpoint_sandbox</Name>
			<Description>JWKS endpoint of sandbox</Description>
		</Attribute>
		<Attribute required="false">
			<Name>software_jwks_endpoint_production</Name>
			<Description>JWKS endpoint of production</Description>
		</Attribute>
	</ApplicationAttributes>
</ApplicationConfiguration>

This is available only as a WUM update and is effective from November 13, 2019 (11-13-2019). For more information on updating WSO2 Open Banking, see Updating WSO2 Products.

In the API Store, you can display both name and ID of the application if you have enabled UseSoftwareIdAsApplicationName feature and configured the software_client_name attributes.

  1. Add the following to the <WSO2_OB_APIM_HOME>/repository/conf/api-manager.xml file under <ApplicationAttributes>

    <Attribute required="false">
    	<Name>software_client_name_sandbox</Name>
    	<Description>Software Client Name of the sandbox</Description>
    </Attribute>
    <Attribute required="false">
    	<Name>software_client_name_production</Name>
    	<Description>Software Client Name of the production</Description>
    </Attribute>
  2. Add the given key-value pair to the following files: 

    "ID": "ID"
    1. <WSO2_OB_APIM_HOME>/repository/deployment/server/jaggeryapps/store/site/conf/locales/jaggery/locale_default.json
    2. <WSO2_OB_APIM_HOME>/repository/deployment/server/jaggeryapps/store/site/conf/locales/jaggery/locale_en.json

Once you follow the above instructions, notice the additional column Name under the Applications tab of the API Store, which displays softwareClientName.

Registering an application 

To get the public transport and signing certificates, enrol the TPP in the Open Banking Directory and upload the Certificate Signing Request (CSR).

The API allows the TPP to request the ASPSP to register a new client. The process is as follows:

  1. The TPP sends a registration request,

    1. This is a POST request including an SSA (Software Statement Assertion) as a claim in the payload.

    2. The SSA is sent as a signed JWT, which is obtained from the Open Banking Directory. This contains the client metadata.

      The software statement (SSA) should be obtained from the Open Banking Directory by the TPP. The SSA is a signed JWT issued by the Open Banking directory.

    The automated DCR process is carried out by calling a synapse API in the gateway. The registration request relies on Mutual TLS authentication for TPP authentication. 
    An example request sent to the DCR registration endpoint is shown below: 

    curl -X POST \
      https://localhost:8243/open-banking/v3.2/register \
      -H 'Content-Type: application/jwt' \

The request consists of one path parameter named ClientId that the TPP wants to retrieve details for.

  • If the request is successful and the identifier (ClientId) matches the client to whom the Client Credentials grant access token was issued, the ASPSP returns details of the requested client
  • If the ClientId is unknown, the ASPSP responds with an Unauthorized status code and immediately revokes the access token

Deleting an application

The API allows the TPP to request the ASPSP to delete an existing client. The request relies on Mutual TLS authentication and application access token (Client Credentials grant type) for TPP authentication. 

 Click here for a sample application access token
curl -X POST \
  https://localhost:8243/token \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -H 'ssl.client.auth.cert.X509: MIIFODCCBCCgAwIBAgIEWcVqyzANBgkqhkiG9w0BAQsFADBTMQswCQYDVQQGEwJH' -k \
  -d 'grant_type=client_credentials&scope=openid%20&client_assertion=eyJraWQiOiJoY2dleHVndVZiNXJZU1lWQnNsLWM5aEJQdlkiLCJhbGciOiJQUzI1NiJ9.eyJzdWIiOiJ1aHo5NWVTaUtrMmxUeld4YzRqckxUWHh3RThhIiwiYXVkIjoiaHR0cHM6Ly9sb2NhbGhvc3Q6ODI0My90b2tlbiIsImlzcyI6InVoejk1ZVNpS2sybFR6V3hjNGpyTFRYeHdFOGEiLCJleHAiOjE1OTkxODcyMDEsImlhdCI6MTU3MDA3NjUyNiwianRpIjoiMTU1NDE5MjU0MTkifQ.sb-lwJhbtbaPrCvftyNcDLUt3uqtANXdJkbCNG6x7BL57b4cqkxo20BKHn4Cnvd8f00OIfuEQLBKo5BH9bpkt06MVsoZdEhq4YMT_FqUZb_38B-MEmWuaE2n6-ZCa_Jlp8TZ49PRY_q-Zz-y8WkDF2Hy51lulL5exxq0eGfNzGNMHk9_yQeEPte2-IY7NHPNpY0WpPKpYTUHPvDC3u_o5oL7WAcdE5bwqZQ4M5VcQf_QSqVLxrRpFv2FO9FBiU_iTG1S9CgNrYICzlgk9Gg2DhFu75iqcrjpGiEcXjSULKwRT89j--jJMWSCSuJ64OFllao3x56JecxxGdlA0HuaSw&client_assertion_type=urn%3Aietf%3Aparams%3Aoauth%3Aclient-assertion-type%3Ajwt-bearer&redirect_uri=https%3A%2F%2Fwso2.com%2F'

The request consists of one path parameter namely ClientId of the TPP which should be deleted. 

  • If the request is successful and the ClientId  matches the client to whom the Client Credentials grant access token was issued, the ASPSP must delete the client and invalidate long lived access tokens that were issued to the client
  • If the ClientId is unknown, the ASPSP responds with an Unauthorized status code and immediately revokes the access token

You can find a sample request sent to the retrieving endpoint below.

curl -X DELETE \
  https://localhost:8243/open-banking/v3.2/register/Kz_LXAWqCn3CVlp26uWS9MzVH1ca \
  -H 'Authorization: Bearer f044e75d-9c11-3133-b60b-9a36e5a0ed80' \
  -H 'Content-Type: application/jwt' -k

If the deletion is successful you will get a 204 No Content response.
