Free Microservice and webhook hosting –

A Microservice cannot be defined in a specific way but they are small processes which are a part of an application. A simple API which lets a user create and read data from your database can be called as a Microservice.

Microservices are modular, mostly independent and easy to maintain.

Microservice hosting is an open source platform which provides microservice and webhook hosting. It makes deploying microservices very easy.

How it works doesn’t let you run a server but it lets you run a microservice on their server. Each microservice is represented by a single function matched to a single unique URL.

Create a microservice and connect some code to it. Whenever a request is made to its unique URL, the code will be executed. It is as simple as that.

Create a free developer account on first, then log in and click on create a new service.

create microservice demo

Give a name for service, A unique URL will be created for your microservice. Scroll down, choose programming language > add code in code editor > save. Your microservice is ready.

Deploying facebook chat bot to

If you followed Build chat bot for facebook messenger using Javascript – Part 1 and Part 2 then this section shows how to use the same code to deploy chat bot in hookio

Create a new service, give it a name and add the following code in code editor :

module['exports'] = function handleMessage (hook) {
  	if (hook.params['hub.verify_token'] === 'verifycode') {
  var messaging_events = hook.params.entry[0].messaging;
    for (i = 0; i < messaging_events.length; i++) {
        event = hook.params.entry[0].messaging[i];
        var sender =;
        if (event.message && event.message.text) {
            var text = event.message.text.toLowerCase().trim();
          	if (text.toLowerCase().substr(0,4) == 'wiki') {
                wikibot(text.replace("wiki ", ""),sender)
            else {
      	else if(event.postback && event.postback.payload){
           sendMessage(sender,event.postback.payload) ;

Then add wikibot, sendHelp and sendMessage functions just below this function. Use URL of this microservice in facebook developer platform account to setup webhooks and your facebook chat bot is live!
