Payout

In order for the user to redeem his collected rewards, they must be paid out. A reward can only be paid out exactly once.

For an easier integration process and a more seamless user experience, we highly recommend using the server-side reward handling as laid out on this page. If you cannot handle the rewards via server and you need to handle them inside the app, please refer to this section instead.

Server-to-server payout

In order to use the server-to-server payout, you need to create an endpoint on your server that we can request in order to notify you of the user's rewards. Once you receive the notification, it will be up to you to deliver it to the user.

We highly recommend using server-to-server payout for rewards due to higher security and better transparency on your end.

Endpoint structure

We will call your endpoint with an HTTP GET request and the configured parameters:

Parameter	Detail	Format	Type
user_uuid	The Id of the user that should get the rewards	string	mandatory
sid	The request signature, which should be used to verify request authenticity. sid is computed as a SHA1 hash of the request parameters as sid = sha1(concatenate(trans_uuid, user_uuid, currency, coin_amount, device_id, sdk_app_id, s2s_token))	string	mandatory
coin_amount	The amount of virtual currency the user should get	integer	mandatory
currency	The name of the virtual currency	string	mandatory
trans_uuid	The unique transaction ID	UUID v4	mandatory
device_id	optional device id	string	optional
app_name	URL encoded app name in English	string	optional
sdk_app_id	optional app id of the sdk	string	optional
app_id	optional app id that generate the usage	string	optional
sdk_sub_id1	optional sub id one passed from SDK to track the request	string	optional
sdk_sub_id2	optional sub id two passed from SDK to track the request	string	optional
reward_level	optional reward level	string	optional
reward_type	optional reward type	string	optional

Security

To ensure that requests come from us, you should calculate the sid parameter and compare it to the parameter sent in the callback. It is calculated as follows: sid = sha1(concatenate(trans_uuid, user_uuid, currency, coin_amount, device_id, sdk_app_id, s2s_token)) We will supply you with the parameter s2s_token separately.

Example Endpoint URL: https://example.com/example?[YourParamName]={user_uuid}&[YourParamName]={sid}&[YourParamName]={coin_amount}&[YourParamName]={currency}&[YourParamName]={trans_uuid}&[YourParamName]={sdk_sub_id1}&[YourParamName]={sdk_sub_id2}
