Mulesoft Adapter

MuleSoft (Anypoint Platform™) is a platform that helps app developers to design custom APIs and deploy to a Mule Enterprise Service Bus runtime (ESB). With MuleSoft integration service in Quantum Fabric, developers can interact with more than 50 types of adapters.

To integrate a MuleSoft service in Quantum Fabric, developers need to create a project in MuleSoft Studio, export the project to a local system, and then deploy it to Cloud Hub. On top of the project deployment, a RESTful API modeling language (RAML) file needs to be built, which defines all the API definitions in the project. A RAML file also contains the defined schemas with properties. When a user creates a project from AnyPoint API Studio with any adapter and builds a RAML file over the project, all the APIs can be used in Quantum Fabric integration service. When a Quantum Fabric user selects a MuleSoft adapter from Quantum Fabric Console, based on the cloud hub portal credentials of the MuleSoft adapter, the system retrieves metadata from a RAML file and displays all APIs of a RAML file. Developers can add these APIs as operations in MuleSoft integration service in Quantum Fabric Console.

Quantum Fabric discovers the MuleSoft endpoints through a RAML file. Quantum Fabric parses a RAML file and exposes all the MuleSoft endpoints through the integration service. Mobile app developers can use the configured MuleSoft integration service and access the backend systems supported by MuleSoft’s adapters.

NOTE: In Quantum Fabric Console, you can provide login credentials of MuleSoft or upload a RAML file to configure an integration service.

Advantages

  • Developers can design custom APIs
  • Developers can use more than 50 types of connectors.

Limitations

  • When an APIGroup is created, only one RAML file needs to be created. Multiple files are not supported.
  • Reconfiguration of apps during publish is not supported for MuleSoft.
  • The schema defined must always be in JSON format. XML schema is not supported.
  • API Gateway (On-premises / Cloud) and Mule ESB (On-premises) are not supported.

Prerequisites

Adding a MuleSoft service involves the following steps:

Configure MuleSoft End-point Adapter

To configure a Mulesoft adapter in Integration Service Definition tab, follow these steps:

  1. In the Name field, provide a unique name for your service. When you enter the name, the name is updated for the active service under the Services section in the left pane.
  2. From the Service Type list, select Mulesoft.

    NOTE: XML is selected, by default.

  3. Provide the following details to create a SOAP service.
    FieldsDescription
    VersionSelect the version for the service.
    Choose API Discovery Type
    • RAML File - Select the option and upload RAML file from your local machine.

      The system adds your RAML file to the console. The system displays the added RAML file's name under the Choose API Discovery Type section.

    • AnyPoint Platform URL - Select this option and the system displays the MuleSoft URL in the text box.

      Under the User ID and Password, provide valid log-in credentials that you created while registering with MuleSoft AnyPoint Platform.

      NOTE: You cannot modify the details in AnyPoint Platform URL.

      Click Test Login to test the Mulesoft connection details.

  4. Field Description
    Custom code

    To specify a JAR associated to the service, select one from the Select Existing JAR drop-down menu or click Upload New to add a new JAR file. Make sure that you upload a custom JAR file that is built on the same JDK version used for installing Quantum Fabric Integration.

    IMPORTANT: Make sure that you upload a custom JAR file that is built on the same JDK version used for installing Quantum Fabric Integration.

    For example, if the JDK version on the machine where Quantum Fabric Integration is installed is 1.6, you must use the same JDK version to build your custom jar files. If the JDK version is different, an unsupported class version error will appear when a service is used from a device.
    API Throttling
    • If you want to use API throttling in Quantum Fabric Console, to limit the number of request calls within a minute. do the following:

      1. In the Total Rate Limit text box, enter a required value. This will limit the total number of requests processed by this API.

      2. In the Rate Limit Per IP field, enter a required value. With this value, you can limit the number of IP address requests configured in your Quantum Fabric console in terms of Per IP Rate Limit.

    • To override throttling from Quantum Fabric App Services Console, refer to Override API Throttling Configuration.

      NOTE: In case of On-premises, the number of nodes in a clustered environment is set by configuring the KONY_SERVER_NUMBER_OF_NODES property in the Admin Console. This property indicates the number of nodes configured in the cluster. The default value is 1.
      Refer to The Runtime Configuration tab on the Settings screen of App Services.

      The total limit set in the Quantum Fabric Console will be divided by the number of configured nodes. For example, a throttling limit of 600 requests/minute with three nodes will be calculated to be 200 requests/minute per node.
      This is applicable for Cloud and On-premises.
    Use proxy from settings To enable the proxy, select the check box. The Use proxy from settings check box dims when no proxy is configured under the Settings > Proxy.

    NOTE: All options in the Advanced section are optional.

      Value

      Three different options are available in Quantum Fabric under VALUE during configuration of any operation. When you start editing this field, dependent identity services are auto populated. These options primarily determine the source of the value of the header.

      • Request: If this option is selected, the Integration Server picks the value pairs from the client's request during run time and forwards the same to the back-end.

        User has the option to configure the default value. This default value is taken if the request does not have the header.

      • Session: If this option is selected, the value of header is picked from session context based on the user configuration.
      • Identity: If this option is selected, you can filter the request parameters based on the response from the identity provider. For more details to configure identity filters, refer to Enhanced Identity Filters - Integration Services.

      NOTE: The field is set to Request, by default.

      NOTE: For more information on Externalizing Identity Services, refer to Replace the Identity Service references in a Fabric app.

      TEST VALUEEnter a value. A test value is used for testing the service.
      DEFAULT VALUEEnter the value, if required. The default value will be used if the test value is empty.
      Scope

      Select request or session. This field is set to Request, by default.

      The default datatype for the selected column is loaded under DATATYPE field.

      EncodeSelect the checkbox to enable an input parameter to be encoded. For example, the name New York Times would be encoded as New%20York%20Times  when the encoding is set to True. The encoding must also adhere the HTML URL encoding standards.
  5. Click the Header tab to provide the following customer headers, perform the following actions:

    You must provide the custom HTTP headers based on the operation. For example, post or get.

    1. To configure parameters in the client's header, do the following:
      FieldDescription
      NameProvide custom HTTP headers required by the external source.
      Value

      Three different options are available in Quantum Fabric under VALUE during configuration of any operation. When you start editing this field, dependent identity services are auto populated. These options primarily determine the source of the value of the header.

      • Request: If this option is selected, the Integration Server picks the value pairs from the client's request during run time and forwards the same to the back-end.

        User has the option to configure the default value. This default value is taken if the request does not have the header.

      • Session: If this option is selected, the value of header is picked from session context based on the user configuration.
      • Identity: If this option is selected, you can filter the request parameters based on the response from the identity provider. For more details to configure identity filters, refer to Enhanced Identity Filters - Integration Services.

      NOTE: The field is set to Request, by default.

      NOTE: If the header value is scoped as a Request (or) Session and the same header is accessed under the Expression header value, then the expression must be represented as $request.header (or) $session.header.



      Example: If a header 1 value is a request and header 2 value is an expression, then the value of the expression must be $Request.header1.
