Configuring the callback functionality.

• Please contact the third party app developers and get them to implement their app logic in our callback functionality.

• They have to add the following code in the Cart page file of your theme coding in which they will pass their app logic with the return value as true or false.

function hulkappsCheckoutClick(){


return true;

return false;


• Save the file and you are good to go.
