Follow the instructions below to import a single API from WSO2 API Manager and create a Microgateway distribution for it.

Step 1 - Follow the installation prerequisites

Make sure to carry out all the installation prerequisites.

Step 2 - Create a Microgateway project

Let's initialize a API Microgateway project named marketing_project. Navigate to a preferred folder where you want to create the Microgateway project. Thereafter, run the following command.

micro-gw init <project-name>
micro-gw init marketing_project
Project 'marketing_project' is initialized successfully.

Step 3 - Build the Microgateway project

  1. Import the API, which is published in WSO2 API Manager.

    micro-gw import -a <API_name> -v <version> <project_name> 
    micro-gw import -a PizzaShackAPI -v 1.0.0 marketing_project

    WSO2 API Microgateway Toolkit prompts for the following.

    • Username and Password - Enter your user credentials. The username and password should correspond to a valid user in WSO2 API Manager

    • APIM base URL - This is the WSO2 API Manager URL. If you want to use the default value, click enter.

    • Trust store location and password of WSO2 API Microgateway Toolkit - If you want to use the default value, click enter.

    Enter Username: 
    Enter Password for admin: 
    Enter APIM base URL [https://localhost:9443]: 
    You are using REST version - v0.14 of API Manager. (If you want to change this, go to <MICROGW_HOME>/conf/toolkit-config.toml)
    Enter Trust store location: [lib/platform/bre/security/ballerinaTruststore.p12]
    Enter Trust store password: [ use default? ]
    ID for API 30e623704c5c5479b7c0d9ab78e965df02c1610401e37cbd557e6353e3191c76

    After the API is imported, you can find the auto-generated Swagger definition in the <MGW-project>/gen/<Swagger-file-name>.JSON directory of the project (e.g., /marketing_project/gen/30e623704c5c5479b7c0d9ab78e965df02c1610401e37cbd557e6353e3191c76swagger.json)

  2. Build the WSO2 API Microgateway project (e.g.,marketing_project).
    Navigate to the <MGW_HOME>/bin directory and run the following command.

    micro-gw build <project-name>
    micro-gw build marketing_project
    Compiling source
    Running tests
    	No tests found
    Generating executable

    This creates an executable file (/marketing_project/target/marketing_project.balx) that you can use to expose the API via WSO2 API Microgateway.

Step 4 - Run the Microgateway

Start WSO2 API Microgateway as follows:

Format - Linux/Mac OS
gateway <path-to-MGW-executable-file>
Format - Windows OS
.\gateway.bat <path-to-MGW-executable-file>
Example - Linux/Mac OS
gateway /Users/kim/Downloads/TestProj/marketing_project/target/marketing_project.balx

WSO2 API Microgateway starts for the API.
