What’s it all about

We are launching a new type of games on our platform - hypercasual games.

We are trying to make their launch on our platform as easy as it could be. How it differs from common games:

  • you don’t need to implement in-app payments in your game. Ads monetization only is fine for us;
  • you don’t need to implement any social mechanics (by implementing them would be great) like user communications, publishing user topics or any other social stuff;
  • new and hypercasual games only featuring mechanics will be available on our platform.

To launch such an app it’s required to:

  • get a developer access for yourself;
  • create an API application on our platform;
  • identify OK users on game launch;
  • implement an ads monetization;
  • successfully pass our moderation review.

How to get developer access

To acquire an access to developer-only sections of OK you need to get developer access on this page: ok.ru/devaccess

All users planning to have an access to your app before it’s publication must get developer access.

How to create and set up an application

After you’ve finished getting developer access you now can create an API application. This app will be used as an entry point for your game. Also it’s required to work with our API.

To create an app you can follow this instructions

Make sure when setting it up you’ve enabled following platforms:

  • web;
  • mobile.

As an app’s link you must specify your game’s URL.

After app is created an email with essential app’s data will be sent to you. It will contain following information:

  • ID - unique application identifier;
  • secret key - it’s used to access app’s settings;
  • public key - it’s used for OK API access.

Don’t forget to keep these keys safe.

After you’ve correctly set up an application it will be available for it’s creator by this links:

  • https://m.ok.ru/game/appId - on mobile platforms;
  • https://ok.ru/game/appId - on desktop.

It will also be displayed in a special “my uploaded games” section of games in our mobile apps for android and iOS platforms.

How to make a game available for other developers

If another user needs an access to your “under development” game on out platform (i.e. for testing it) follow these three steps:

  • user must get a developer access here;
  • app’s creator and this user must be friends on OK;
  • app’s creator can then add this new developer to app’s developers list following this instructions

How to identify OK user in your game

After app is correctly set up when it is accessed via https://ok.ru/game/gameId link your game will be opened on our platform in an iframe.

In a query part of an URL a dozen of other parameters will be passed to your app:

  • logged_user_id - unique user identifier;
  • user_name - user’s name and surname;
  • user_image - user’s avatar URL;
  • user_gender - user’s gender. 1 - male, 2 - female.

This is not a full list of parameters. Full list can be seen here.

Ads monetization

Two types of ads monetization are available for games on our platform:

  • rewarded ads;
  • interstitial ads.

Using our SDK is quite easy. You need to:

  • add FAPI script to your game’s code;
  • specify a callback function;
  • use two SDK methods to find and show an ad.

Rewarded ads

To impement this type of ads in your game following two SDK methods should be used in your game:

These methods are available on all our platforms (desktop web, mobile web, android and iOS apps).

Interstitial ads

This type of ads requires a single SDK method to be implemented:

Interstitial ads are available only on android platform at the moment.

Setting up FAPI

It’s enabled in your game by adding a single line of code:

<script type="text/javascript" src="//api.ok.ru/js/fapi5.js" defer="defer"></script>

Callback function

Methods from the FAPI.UI group don’t require the callback function to be passed. After the method is executed, a global function will be called, and the developer must realize it. The function must have the signature:

function API_callback(method, result, data);

Here:

  • method - the name of the method called
  • result - the result of the execution (“ok” if successful, “cancel” if the user canceled the action)
  • data - additional information, for example, for showInvite() – a list of IDs of invited friends, separated by commas, in the string format.

Finding a rewarded ad

Example usage

function prepareRewardedAd() {
    FAPI.UI.loadAd();
}

Displaying a rewarded ad

Example usage

function showRewardedAd() {
    FAPI.UI.showLoadedAd();
}

Displaying an interstitial ad

Example usage

function showInterstitialAd() {
    FAPI.UI.showAd();
}

Game moderation

After your app is ready to be launched it needs to be moderated by us.

To create a moderation request you just need to fill up a moderation form

If everything went good you’ll get an email with account credentials for our moderation JIRA.

Starting from this point communications will be processed there.
