Initialization

Once the customer is linked, the customer's id can be requested as follows:

 Indigitall.getCustomer(this, object : CustomerCallback(this){
   override fun onSuccess(customer: Customer) {
     //do something
   }

   override fun onError(errorModel: ErrorModel?) {
     //log error
   });

And the customer's information about its fields as follows:

Indigitall.getCustomerInformation(context, null, object: CustomerFieldCallback(context){
   override fun onSuccess(customerField: ArrayList<CustomerField>) {
   		//do something
  }

  override fun onError(error: Error?) {
      //log error
  }
})
