Add content to different collections using http-function.js

Hello, I am using the code below to post content to a collection using Zapier.
How can I publish content in several differents collections, using the same code please?
Where to insert the code for the other collections without breaking the JS?
Thanks for your help.

'use strict';
import {ok, response, serverError, badRequest} from 'wix-http-functions';
import wixData from 'wix-data';
export function post_addthings(request) { // POST = Method
return request.body.json()
    .then(body => {
 let recordInsert = {
 "title":  body.title,
 "description": body.description,
 "source": body.source,
 "image": body.image,
        };
 return wixData.insert('Database', recordInsert)
            .then(result => ok({body: JSON.stringify(result)}))
            .catch(err => response({status: 500, body: err}));
        }
    );
}
