Dynamic Client Registration

This page explains how to onboard TPP applications using the Dynamic Client Registration API.

Step 1: Deploy the Dynamic Client Registration(DCR) API¶

1. Sign in to the API Publisher Portal at https://localhost:9443/publisher with creator/publisher privileges. You can use the credentials for [email protected].

2. In the homepage, go to REST API and select Import Open API.

3. Select OpenAPI File/Archive.

4. Click Browse File to Upload and select the <APIM_HOME>/<OB_APIM_TOOLKIT_HOME>/repository/resources/apis/ openbanking.org.uk/DynamicClientRegistration/3.3.0/dynamic-client-registration-swagger.yaml file.

5. Click Next.

6. Click Create to create the API.

7. After the API is successfully created, go to Portal Configurations using the left menu panel.

8. Select Subscriptions from the left menu pane and set the business plan to Unlimited: Allows unlimited requests.

9. Click Save.

10. Once you get the message that the API is successfully updated, add a custom policy. Follow the instructions given below according to the API Manager version you are using:

    Click here to see how to add a custom policy if you are using API Manager 4.0.0...

    1. Use the left menu panel and select API Configurations > Runtime.
       

    2. Click the Edit button under Request > Message Mediation.

    3. Now, select the Custom Policy option.

    4. Upload the <APIM_HOME>/<OB_APIM_TOOLKIT_HOME>/repository/resources/apis/openbanking.org.uk/DynamicClientRegistration/3.3.0/dcr-dynamic-endpoint-insequence-3.3.0.xml file.

    5. Click Select.

    6. Scroll down and click SAVE.

    Click here to see how to add a custom policy if you are using API Manager 4.1.0...

    1. Go to Develop -> API Configurations -> Policies in the left menu pane.
       
       

       

    2. On the Policy List card, click on Add New Policy.

    3. Fill in the Create New Policy.

    4. Upload the <APIM_HOME>/<OB_APIM_TOOLKIT_HOME>/repository/resources/apis/openbanking.org.uk/DynamicClientRegistration/3.3.0/dcr-dynamic-endpoint-insequence-3.3.0.xml file.

    5. Scroll down and click Save. Upon successful creation of the policy, you receive an alert as shown below:
       
       

       

    6. Expand the API endpoint you want from the list of API endpoints. For example:

    7. Expand the HTTP method from the API endpoint you selected. For example:

    8. Drag and drop the previously created policy to the Request Flow of the API endpoint.

    9. Select Apply to all resources and click Save.

    10. Scroll down and click Save.

    1. Use the left menu panel and go to API Configurations > Endpoints.

11. Add a Dynamic Endpoint.

12. Go to Deployments using the left menu pane.

    

13. Select the API Gateway type, in this scenario, it is Default.

14. Click Deploy.

15. Go to Overview using the left menu pane.

    

16. Click Publish.

17. The deployed API is now available in the Developer Portal at https://localhost:9443/devportal.

18. Upload the root and issuer certificates in OBIE (Sandbox certificates/ Production certificates) to the client trust stores in <APIM_HOME>/repository/resources/security/client-truststore.jks and <IS_HOME>/repository/resources/security/client-truststore.jks using the following command:

    keytool -import -alias <alias> -file <certificate_location> -storetype JKS -keystore <truststore_location> -storepass wso2carbon

19. Restart the Identity Server and API Manager instances.

Step 2: Configure IS 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.

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

7. Disable the Resident Key Manager.

Step 3: Register an application¶

TPPs use the DCR API to request the ASPSP to register a new client.

The registration request is a POST request that includes a Software Statement Assertion (SSA) as a claim in the payload. This SSA contains client metadata. It is a signed JWT issued by the Open Banking directory and the TPPs need to obtain it before registering with an ASPSP.

This section explains the client registration process. A sample request is as follows:

For the Transport Layer Security purposes in this sample flow, you can use the attached private key and public certificate.

curl -X POST https://<APIM_HOST>:8243/open-banking/v3.3.0/register \
-H 'Content-Type: application/jwt; charset=ISO-8859-1' \ 
--cert <TRANSPORT_PUBLIC_CERT_FILE_PATH> --key <TRANSPORT_PRIVATE_KEY_FILE_PATH> \

• The bank registers the application using the metadata sent in the SSA.

• If an application is successfully created, the bank responds with a JSON payload describing the application that was created. The TPP can then use the identifier (Client ID) to access customers' financial data on the bank's resource server. A sample response is given below:
