This article describes how to add a new API user in Hermod to get a unique API key for authentication to the API.


Step-by-step instruction

To configure Hermod, do the following:

  1. Open Hermod Config file:
    1. For Hermod docker image: 
      1. Navigate to the top-level directory where docker-compose.yml is located. The configuration file should then be found in a config/ directory.

        mydir/ 
        |-- cacerts 
        |-- certificates 
        |-- config 
        | 
        |-- application.yml -> cod-hermod.yml 
        | `-- cod-hermod.yml 
        `-- docker-compose.yml


      2. Open the configuration file for editing:

        vi config/cod-hermod.yml


        Application.yml is a link to cod-hermod.yml
        Application.yml is the actual file used by the server. 


    2. For Hermod WAR file: 
      1. Navigate to and open for editing application.yml.
        Default file path: /wbapps/hermod/WEB-INF/classes/application.yml 
  2. Open a browser and go to the following URL, using a unique <myclientid>:

    http://localhost:20400/<contextPath>/<uriBase>/util/generateclient/<myclientid>
    
    The default value for /<contextPath>/<uriBase> is /hermod/rest


    All requests below are triggered from the host itself, thus localhost is used.

    The port number (20400 in the example above) might have been assigned a different value. To find out the current port number, do the following:

    • For docker: type the command:
      docker ps | grep hermod_hermod
    • For tomcat: check server.xml


  3. Copy the content from the resulting web page and paste it into the allowed-clients section of the configuration file. 

    The username and password must match the username and password for the dedicated user that has been added in Identity Manager, see Integrate Identity Manager with Smart ID Messaging.

     

    # X-Api-Key: a2Fyb2xpbjpmZDA0ZGUyZjFlNTU0NGIyOTE1ZDFhNjUwOThjNDkwNjM3YTA3MTVmNWM5ODQzNDU5ZjA1ZGZjMjk4MzQyOTM2 
    - client-id: <myclientid> 
        key: fd04de2f1e5544b2915d1a65098c490637a0715f5c9843459f05dfc298342936
        # Optional username:password to be supplied for basic authentication in callbacks
        callback-basic-auth: username:password
        # The callback URL base for this specific client
        callback-url: http://localhost:20400/hermod/rest


    X-API-Key, which is the base64-encoded value of client-id:key, is the key you need to configure in clients, such as Smart ID Identity Manager

    Do not add any extra spaces in the configuration file, the .yml file format is space sensitive.


  4. Edit callback-url to receive the callbacks from the Hermod API.
    Also edit username and password if the callback URL requires basic authentication.

  5. Optional - If visual data is to be fetched from an external content provider:
    1. Configure content-provider-url to point to the Content provider API.
    2. Also edit user and pwd if the content provider requires basic authentication.

          # Optional: username and password to be supplied for basic authentication to the content provider
          content-provider-basic-auth: user:pwd
          # Optional: The URL to the content provider API
          # When Identity Manager is used as content provider, the URL will look like this: https://<IDM-OPERATOR>/ws/hermod/contentprovider/getcontent
          content-provider-url: https://myprovider/getcontent


  6. Save and exit the configuration file.


  1. Refresh the configuration:

    curl -X POST http://localhost:20400/<contextPath>/refresh


  2. Test the new key by sending a request using curl (set THE-NEW-KEY below):

    curl -w%{http_code} -X POST \
      http://localhost:20400/<contextPath>/<uriBase>/command/ping \
      -H 'cache-control: no-cache' \
      -H 'content-type: application/json' \
      -H 'x-api-key: THE-NEW-KEY' \
      -d '{
      "commandHeader" : {
        "to": ["api-test"]
      }
    }'


  3. Check the response.
    1. If you get a 403 response, you have the wrong API key.
    2. If you get a 404 response, then you have the correct API key. A 404 response means that the user api-test isn't found, which is expected at this point.
