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

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}
