Build RAML or OAS API Proxies

API Manager 2.x enables you to use a RAML or OAS type of API Proxy, for all your Mule 4 based proxies.

Configuring your RAML or OAS API Proxy

Configure your RAML or OAS API proxy by completing the following steps:

  1. Navigate to Anypoint Platform > API Manager.

  2. In API Administration, click Add API and select Add new API.

  3. Select Mule Gateway as your runtime.

  4. Select Deploy a proxy application for Proxy type.

  5. If you selected to deploy a proxy application, select the Target type from the following options:

    • CloudHub 2.0: Select this option if you want to use the Mule runtime hosted by MuleSoft in a container-based cloud infrastructure. The CloudHub 2.0 proxy includes a CPU with 0.1 vCores by default.

      1. Select a space.

        To learn more about spaces, see Shared Spaces and Private Spaces.

      2. In Runtime version:

        1. Select the Runtime Channel.

        2. Select the Version for Mule runtime.

        3. Select the Java version.

      3. Enter a Proxy app name.

    • CloudHub: Select this option if you want to use the Mule runtime hosted on the cloud by MuleSoft. The CloudHub proxy includes a CPU with 0.1 vCores and a memory of 500 MB, by default.

      1. In Runtime version:

        1. Select the Runtime Channel.

        2. Select the Version for Mule runtime.

        3. Select the Java version.

      2. Enter a Proxy app name.

    • Hybrid: Select this option if you want to use a Mule runtime instance running on an on-premises server that is registered in Runtime Manager.

      See Register a server in Runtime Manager for more information.

      1. Select a target from the list or click Add server.

      2. Enter a Proxy app name.

    • Self-managed Server: Select this option if you want to create a JAR file to deploy an API proxy to a Mule runtime instance running on an on-premises server that is not registered in Runtime Manager. For more information, see On-Premises Deployment Model.

Deploying an API proxy to a self-managed server in API Manager doesn’t deploy the proxy to your on-premises server. After you deploy the proxy in API Manager, deploy the proxy to your on-premises server: . Download your new API proxy JAR file. . Deploy the JAR file to your on-premises server.

  • Runtime Fabric: Select Runtime Fabric if you want to deploy API Proxies to a Mule runtime engine that is managed on Runtime Fabric. See Deploying API Proxies to Runtime Fabric for more information.

    1. Select a target from the list.

    2. In Runtime version:

      1. Select the Runtime Channel.

      2. Select the Version for Mule runtime.

      3. Select the Java version.

    3. Enter a Proxy app name.

      1. Select an API from the following options:

  • Click Select API from Exchange if you have an API shared with you through Exchange that you want to manage.

    1. Click the API from the list under Select API. You can search for a specific API if needed.

    2. Update the Asset type, API version, and Asset version if you are not using the latest version.

      For more information about versions in Exchange, see Asset Versions.

    3. If you chose a RAML/OAS asset type, view the Conformance Status of the API to ensure the API is conformant. If the Conformance Status is nonconformant, after deployment, view the Governance Report to find and fix the conformance issues. For more information about the Governance Report, see Governing API Instances.

  • Click Create new API:

    1. Enter a Name for the new API asset.

    2. Select REST API as the Asset type.

    3. Upload either a RAML or OAS file for your REST API.

      Anypoint API Manager supports OpenAPI Specification (OAS) 3.0, with the exception of the callback feature. To work around this issue, handle the callback outside of the Mule runtime engine domain or use an OAS 3.0 specification that does not use callbacks.

    4. Update the Asset type, API version, and Asset version if you are not using the latest version.

      For more information about versions in Exchange, see Asset Versions.

    5. View the Conformance Status of the API to ensure the API is conformant. If the Conformance Status is nonconformant, after deployment, view the Governance Report to find and fix the conformance issues. For more information about the Governance Report, see Governing API Instances
