Write your First mesibo Enabled Application

Estimated reading time: 3 minutes

Excited to see real-time messaging in action? We are too. In this first tutorial, we will create a simple real-time app for Android, iOS and Web.


You MUST go through following prerequisites before you read further.

You are not required to go through Real-time API for now.


Before we start coding our first Android, iOS or web application - we need to perform a few steps that are common across platforms. You need to be logged-in to Mesibo console to perform these steps.

Let’s say you are creating a new app BingoMessage for Android, iOS and web. You first need to let mesibo know about this application. You can do it by creating a new application from the Mesibo console.


Once your application is created, note down the App token. The App Token looks like following:


We will need this application token to create users and groups for this application.

Create Users (Endpoints)

Once you have created your Application, it’s time to add users and groups. Typically, you will add users and groups dynamically on need basis. However, for this sample app, you can create a few users and groups manually so that you can test messaging between them.

Note that all your users and groups are local and confined to an Application. So there is no conflict when same user is created by another application.

Now we will create two users by using Mesibo Admin API and the app token obtained in the previous step.

  • 18005550001
  • 18005550002

Note that, you also need to pass the Android app id (bundle id in iOS), for example com.mesibo.demoapp while creating users. This is a security feature that restricts your users from using the user access token on intended platforms only.

User Creation Request



  • token = Application Token
  • appid = Android or iOS app id (for example, com.mesibo.xxx). In case of web, just pass, ‘web’ as appid. Note that, for security reasons, the token generated for a particular appid will only be usable on app matching that appid.
  • addr = end point address, for example, a user phone number.

You can find more about server-side API in the reference section. The above API returns JSON response like this,



The above API returns JSON response with access token, that will be used by real-time API to connect to mesibo real-time server (using setAccessToken API).

You can now create more users in similar fashion so that you test messaging between them. You can also send messages to a particular user from console from ‘Users’ section.

You can also create users from the console by clicking on ‘New User’ button from the Application settings page.

We are now all set to create our first mobile app which can send and receive real-time messages.

In next section, we will learn to create a basic Android application.
