Out of Band Authentication Adapter

Adapter Loading Process

The ActiveAccess ACS performs Out Of Band (OOB) challenges through OOB Adapters, which connect the existing OOB authentication system with ActiveAccess. During 3DSecure 2.0 challenge flows where OOB Authentication is required, the ACS will trigger the external OOB process and perform interactions with the Cardholder via the OOB Adapters.

For this purpose, the ACS communicates with the existing OOB-System via a middleware, known as the OOB Adapter. The OOB Adapter can be either loaded locally by the ACS or communicated via HTTP calls, known as the Native API and REST API versions respectively.

Native API version of OOB Adapter

The Native API version of OOB Adapter is known as oob.adapter in this specification. The Native Adapters are provided in the form of JAR files, by GPayments or ActiveAccess clients. Only Java is supported for the Native API version of OOB Adapter.

Native OOB Adapter developers provide the adapters in one or more JAR files. The oob.adapter implementation in the adapter must implement the Java interface Adapter in the com.gpayments.oob.api.v1 package.

Implementation Steps

The steps for implementing OOB Adapter are:

  1. OOB Adapter developers create a Java project and obtain the corresponding Adapter API library from the ActiveAccess package. This library contains the interface definition for oob.adapter (Native OOB Adapter).

  2. The Native API Adapter should be implemented as a Service based on the OOB interface Adapter. This specific implementation of the service known as service provider. ACS loads this class in startup and uses it in OOB Authentication. The requirement enforced by ACS is that provider class must have a public zero-argument constructor so that it can be instantiated during loading.

  3. A service provider is identified by placing a provider-configuration file in the resource directory META-INF/services. The file's name is the fully-qualified binary name of the service's type, e.g. com.gpayments.oob.api.v1.Adapter. The file contains a list of fully-qualified binary names of concrete provider classes, one per line. Space and tab characters surrounding each name, as well as blank lines, are ignored. The comment character is '#' ('\u0023', NUMBER SIGN); on each line all characters following the first comment character are ignored. The file must be encoded in UTF-8.

Adapter Interface Methods

The Adapter interface has four methods as follows:

  • Method Name: getAdapterInfo

    • Description: Returns information about oob.adapter
    • Input: This method takes no arguments
    • Output: An instance of AdapterInfo class that contains information about oob.adapter should be returned. The AdapterInfo is explained in detail in the AdapterInfo Data Elements section.

  • Method Name: ping

    • Description: Checks whether OOB-Authenticator Server is accessible or not
    • Input: This method takes no arguments
    • Output: The result of OOB Server pinging should be returned in a boolean value. If the server responds to ping successfully, true should be returned, otherwise false should be returned.

RESTful API version of OOB Adapter

For the Restful API version of the oob.adapter, a Restful API needs to be defined similar to the adapter interface. ACS implements the Restful client and the OOB Adapter API Server will be implemented by the client. In this case, no JARs or plugins need to be loaded by ACS. Clients must provide a specific URL for ACS. Known as Adapter-URL in this document and the required REST API endpoints are defined based on this URL.

Note

We also provide a Swagger API for the sample REST OOB Adapter server that is included in release package. To use it, run OOB Server in the installation package and then open https://localhost:8447/swagger-ui.html#/ in your browser.

Get OOB Adapter Information

The ACS sends an HTTP request to get oob.adapter information. The details of this request are:

  • URL: Adapter-URL/adapter-info
  • Request Method: GET
  • Request Parameters: there are not any request parameters for this REST API
  • Response:
    • Name: adapterInfo
    • Format: JSON object of AdapterInfo.
    • Description: For further details on AdapterInfo, refer to the AdapterInfo Data Elements section.

Get OOB authentication result

ACS calls an HTTP API to check if the cardholder is authenticated successfully or not. The details of this REST API are:

  • URL: Adapter-URL/challenge-result/{acsTransactionId}/{oobTransId} (or Adapter-URL/challenge-result/{acsTransactionId} if oobTransId is null.)
  • Request Method: POST

  • Path variables:

    • Name: acsTransactionId
    • Format: String

    • Inclusion: Required

    • Name: oobTransId

Authentication mechanism for the RESTful API version

Certificate based mutual authentication is used as the authentication mechanism for the RESTful API version. The steps are:

  • ACS publishes a CA for adapter communication, known as Adapter CA
  • ACS also issues a server certificate for the adapter.
  • ACS uses a generated client certificate that is issued by the same Adapter CA.
  • The Adapter server implementation must be set up with the CA and mutual authentication provided.
  • ACS will try to connect to the Adapter Server and if the connection can be established then ACS will continue with the adapter, otherwise it throws an error.
