If you are using "lambda-meta" to configure events, you can configure kong as given below

const lm = require('lambda-meta');
const iopipe = require('@iopipe/iopipe')({ token: process.env.IOPIPE_TOKEN });

module.exports = {
    name: 'example-service',
    description: 'Example service',
    timeout: 3,
    warmup: true,
    responseHeaders: {
        'Cache-Control': 'public, max-age=10',
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': '*'
    },
    kong: {
        service: 'example-service',
        host: 'exmaple.com',
        path: '/users'
        method: 'post',
    },

    inputs: {
        apiKey: {
            required: true,
            type: 'String'
        }
    },

    entry: iopipe((event, context, callback) => lm.processRequest(module.exports, event, context, callback)),

    process: async (event, context) => {
        const { apiKey } = context.params;

        return true;
    }
};
