Connection Manager API

Connection Manager API is a component of the Mojaloop ecosystem that allows an administrator to manage the network configuration and PKI information for the Hub and a set of DFSPs.

It provides a REST API, described using a Swagger/OpenAPI document.

The current version uses both cfssl and openssl as the PKI engines which issue and process CSRs and Certificates. The specific version of cfssl that MCM depends on is kept in the Dockerfile as the value of the branch argument ( as in --branch=v1.3.4 ) and can also be specified as an environment variable ( see CFSSL_VERSION below ).

Authentication

The Connection Manager API supports two types of authentication methods for different client types:

1. Browser Clients (SPA): Cookie-based authentication with MySQL session store
2. Machine Clients: JWT/Bearer token authentication via Keycloak

Authentication is implemented using OpenID Connect (OIDC) with PKCE for enhanced security.

See Authentication Documentation for details.

OpenID Connect Authentication

The system uses OpenID Connect authentication, which is a provider-agnostic approach for authentication and authorization. Configure the following environment variables to enable OpenID Connect:

Environment variable	Description	Default Value
OPENID_ENABLED	Enable OpenID Connect authentication	false
OPENID_DISCOVERY_URL	OpenID Connect discovery URL
OPENID_CLIENT_ID	Client ID for OpenID authentication
OPENID_CLIENT_SECRET	Client secret for OpenID authentication
OPENID_REDIRECT_URI	Redirect URI for OpenID authentication	http://localhost:3001/api/auth/callback
OPENID_JWT_COOKIE_NAME	Cookie name for storing the JWT token	MCM-API_ACCESS_TOKEN
OPENID_EVERYONE_ROLE	Role assigned to all authenticated users	everyone
OPENID_MTA_ROLE	DFSP Admin role mapping for OpenID	mta
OPENID_PTA_ROLE	HUB Admin role mapping for OpenID	pta

Password Reset

For OpenID Connect authentication, password reset functionality is handled by the identity provider's own interface rather than through the Connection Manager API. This approach ensures compatibility with any standards-compliant OpenID provider.

Running the server locally

To run the server with all the defaults and no security, the simplest way is to run:

P12_PASS_PHRASE="choose your own password" npm start

The default config requires a mysql db running on the default port.

Once running, you can access the Swagger UI interface

Running the server + db + web UI locally while developing

The API server requires a mysql db. There's also a Web UI https://github.com/modusbox/connection-manager-ui.

To run them together, you can use the following setup:

• Clone this repo and the Web UI repo at the same level
• Use the docker-compose config in this repo to run a mysql DB, the WebUI and the API server

mkdir modusbox
cd modusbox
git clone https://github.com/modusbox/connection-manager-ui
git clone https://github.com/modusbox/connection-manager-api
cd connection-manager-api/docker
docker-compose build
docker-compose up

Once the docker containers are confirmed to be stable and up, you will need to create the initial HUB environment. From a new terminal session, execute the following;

curl -X POST "http://localhost:3001/api/environments" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"name\": \"DEV\", \"defaultDN\": { \"CN\": \"tes1.centralhub.modusbox.live\", \"O\": \"Modusbox\", \"OU\": \"MCM\" }}"

The UI 'localhost' can now be opened in your local browser.

If you want to start the app with auth enabled:

1. create a local copy of docker-compose-auth.yml as in:

cp docker-compose-auth.yml docker-compose-auth.local.yml

( docker-compose-auth.local.yml is git-ignored )

1. Edit docker-compose-auth.local.yml and enter the security details.

2. Run the bundle with:

docker-compose build && docker-compose -f docker-compose.yml -f docker-compose-auth.local.yml up

Testing

• Unit testing:
  • run npm run backend:start as a pre-requisite to npm test
  • run npm test. The tests are implemented using jest. If you need some test certificates, see the test resources readme
• Smoke testing ( zsh script ): run the cmd-line-tester.sh script from a tmp directory
• swagger: see "running the server" below

Functional Tests

Refer to README.

Building a docker image

The server includes a Dockerfile.

There's a set of scripts to build the image and tag it for a local minikube or other environments. Take a look at ./docker-build.sh
