  serverless.yml:

  custom:
    wso2apim:
      apidefs:
        - myAwesomeAPI: # Your API Definition Identifier
          name: "MyAwesomeAPI" # (CANNOT BE UPDATED LATER) Your API Name
          version: "v1" # (CANNOT BE UPDATED LATER) Your API Version, which also forms a part of the API URL ultimately
          rootContext: "/myawesomeapi" # (CANNOT BE UPDATED LATER) Your API Context, which will be exposed by WSO2 API Gateway. Must be unique per Gateway Environment.
          description: "My Awesome API"
          visibility: "PUBLIC"
          backend:
            http: # HTTP-based Backends
              baseUrl: "https://backend:port/123"
              certChain: "file://certs/backend.cer"
          mediationPolicies: # Optional
            in: "log_in_message"
            out: "None"
            fault: "None"
          apiProperties: # Optional
            "property1": "value1"
            "property2": "value2"
          maxTps: 100
          tags:
            - my-awesome-api
            - awesomeness
          swaggerSpec: # Swagger 2.0 / OpenAPI 3.0 specification in YML

• Run sls deploy to create-and-publish (or) update-and-republish API definitions (and associated backend certificates, if supplied) in WSO2 API Manager.

• Run sls info to view the status of API deployment on WSO2 API Manager.

• Run sls remove to delete API definitions (and associated backend certificates, if exists) when there are no active subscriptions exist on those APIs.
