Above is my static dataLayer code snippet. I have created an event named "checkout" in GTM account. But it is not affecting in analytics overview section. Is anything wrong in my code?

EDIT: DataLayer has been updated to this:

dataLayer = []
dataLayer.push({
   'event':'checkout', 
   'transactionType' : 'demo purpose', 
   'transactionId' : '27628SB013442', 
   'transactionTotal': 4760.00,
   'transactionTax' : 480.32,
   'transactionProducts' : [{
      'sku' : '27328SB013442 - 7/1/2016', 
      'name' : 'Client Name', 
      'category' : 'GV1K',
      'price' : 595.00,
      'quantity' : 8
    }]
});

Answer 1

Try to push the checkout event with your e-commerce data, and make sure you use a Transaction type tag to read the data, since this isn't an enhanced e-commerce transaction. Also verify with GA Debugger or in the dev console that you can see the hit. Other than that I think it looks fine.
