Referral Methods

If you need to use a referral method to sign up a new player using a referral link, call the function below to use the referral module. Best use case is in the success of the registration API of your app just call this method

Don’t call the registerPlayer, this method will register the new playerUniqueId

let playerAttributes: [String : Any] = [
"displayName": "Martin spiderman",
"email": "",
"gender": "m",
"mobileNumber": "01280448448",
"dateOfBirth": "2019-08-18T10:11:34.478Z",
"joinDate": "2019-08-18T10:11:34.478Z"
self.gameballApp?.friendReferral(playerUniqueId:"Spiderman5" , playerAttributes: playerAttributes, completion: { result in
print(result)} )

The playerAttributes is optional, so if you haven't created it yet then call the method like this with only the new playerUniqueId.

self.gameballApp?.friendReferral(playerUniqueId:Spiderman5, completion: { result in print(result)
} )

Now, referral links will be generated successfully for your players!
