💡2. Initialize IMP object

Prepare for payment integration using the Merchant ID.

On the checkout page, initialize the IMP object using your Merchant ID.

  var IMP = window.IMP;   // Can be omitted
  IMP.init("Merchant ID"); // Example: imp00000000 

Be sure to initialize the IMP object only once.

Calling a sub-merchant (Tier) payment window

IMP.agency('Merchant ID', 'ABC'); //ABC = Tier Code
