Rewarded video


Incentive video advertisements need to allow users to actively choose to watch. The effect of the advertisement is to issue rewards to users after watching the video advertisement.
Usage scenarios include but are not limited to:

  1. Watch video ads in games and other apps to get in-game coins, etc.;
  2. Integral application access;
    Supported ad sizes: Full screen horizontal screen (aspect ratio 16:9), full screen vertical screen (aspect ratio 9:16). Android does not currently support gravity rotation


Template rendering of rewarded video ads: Provided by default
SDK rendering rewarded video ads: has been recycled and no longer provides creation

Request method

Remarks: There is no difference in the advertising request method for template rendering rewarded video and SDK rendering rewarded video, only the difference in request parameters.
In the incentive video request method of template rendering, the setExpressViewAcceptedSize parameter needs to be set. The value set is greater than 0.

Create TTAdNative object

TTAdNative mTTAdNative=TTAdSdk.getAdManager().createAdNative(this);

Template rendering request AdSlot

AdSlot adSlot = new AdSlot.Builder()
        .setRewardName("金币") //奖励的名称 选填
        .setRewardAmount(3)  //奖励的数量 选填
        .setMediaExtra("media_extra") //附加参数
        .setOrientation(orientation) //必填参数,期望视频的播放方向:TTAdConstant.HORIZONTAL 或 TTAdConstant.VERTICAL

SDK rendering request AdSlot

AdSlot adSlot = new AdSlot.Builder()
        .setRewardName("金币") //奖励的名称 选填
        .setRewardAmount(3)  //奖励的数量 选填
        .setMediaExtra("media_extra") //附加参数
        .setOrientation(orientation) //必填参数,期望视频的播放方向:TTAdConstant.HORIZONTAL 或 TTAdConstant.VERTICAL

Parameter description

Method Description
setCodeId() The code ID created by the platform starts with 9 and 9 digits
setRewardName() The reward name (optional) is consistent with the creation code. Obsolete in 3300 and above
setRewardAmount() The reward quantity (optional) is the same as the one filled in the creation code position. Obsolete in 3300 and above
setExpressViewAcceptedSize() Set the size of the requested template creative. Unit: dp, the value set is greater than 0 (required for template ads)

Method Description
onError() Advertisement request failed callback The returned error code (code) indicates the reason why the advertisement request failed. For details, please see链接
onRewardVideoCached() Callback for the completion of the local loading of the ad video, the local video can be played directly after this callback
onRewardVideoCached(TTRewardVideoAd ad) The callback for the completion of the local loading of the ad video, the local video can be played directly after the callback, and the parameter object can be used to play directly
onRewardVideoAdLoad() Callback when ad loading is complete

Note: In order to ensure the smooth playback of advertising video, it is recommended to call the showRewardVideoAd method in the main thread to display the advertisement after the onRewardVideoCached callback is loaded. After displaying the advertisement, set the advertisement object to null in time

//当mIsLoaded标识为true 代表广告视频本地加载完整 可直接开启一个主线程处理showRewardVideoAd
if (mttRewardVideoAd != null&&mIsLoaded) {
       mttRewardVideoAd.showRewardVideoAd(RewardVideoActivity.this, TTAdConstant.RitScenes.CUSTOMIZE_SCENES, "scenes_test");
       mttRewardVideoAd = null;
     } else {, "请先加载广告");

onRewardVerify Callback description:

  1. The onRewardVerify callback only verifies the video playback status or progress without the user's server reward verification. If the video is played 90% or the playback fails due to an abnormal player, the CSJ will call back onRewardVerify with rewardVerify=true.
  2. In the case of using server-side reward verification, the onRewardVerify callback returns the result of the developer's server-side verification.

Summary: The onRewardVerify callback is only a result of the video playback status or the result returned by the developer, and does not represent advertising business indicators such as whether the playback is billed or not.

onRewardVerify parameter description
Parameter Description
rewardVerify Is it valid
rewardAmount The number of rewards, the value configured when the media platform creates the code bit
rewardName Reward name, the name configured when the media platform creates the code bit
code Error code. New in version 3300
msg msg error message. New in version 3300

Note: Add int code, String msg parameters in the onRewardVerify callback method of SDK3300 version

Need server judgment: the award can be issued based on rewardVerify as the judgment condition
No server judgment is required: rewardVerify returns true by default. The code bit of the test status rewardVerify returns false by default.

Reward distribution mechanism

Refer to this document for reward distribution logic: Link

Server to server callback

The server-to-server callback allows you to determine whether to provide rewards to users who watch the ad. When the user has successfully watched the ad, a verification request will be sent to the verification interface you configured in the CSJ platform, and the developer will determine whether the user will be rewarded for this viewing.
Key Note: The CSJ server only transmits the verification request transparently, and does not add verification logic in the intermediate process. In order to protect the interests of developers and user experience, developers can add their own verification logic in the verification process.

Callback method description

The CSJ server will request the callback link of the third-party service by GET method, and splicing the following parameters to return:

Field name Field definition Field type Remarks
sign Signature string Signature
user_id tagid string Call SDK to pass through
trans_id Transaction string The unique transaction ID that completed the watch
reward_amount rewardAmount int The value configured when the media platform creates the code bit
reward_name rewardName sting The name configured when the media platform created the code bit
extra Extra string Call the SDK to pass in and pass it through, or empty if not needed

Signature generation method

appSecurityKey: The key you obtained from the newly created reward video code bit on the CSJ media platform
transId:Transaction id

sign = sha256(appSecurityKey:transId)

Python Example:

import hashlib
if __name__ == "__main__":
    trans_id = "6FEB23ACB0374985A2A52D282EDD5361u6643"
    app_security_key = "7ca31ab0a59d69a42dd8abc7cf2d8fbd"
    check_sign_raw = "%s:%s" % (app_security_key, trans_id)
    sign = hashlib.sha256(check_sign_raw).hexdigest()

Conventional return parameters

Field name Field definition Field type Remarks
isValid Check result bool Judgment result, whether to issue rewards

According to SDK requirements, the callback url that needs to be judged by the server is a get request. The default return is a json string {"isValid": true}


    "isValid": true

Destroy the ad object

    protected void onDestroy() {
        if (mttRewardVideoAd != null) {
            mttRewardVideoAd = null ;
