Merchant website flowchart starts with going to the merchant's website, adding items in the cart, adding address details, proceeding to payment, selecting the payment method (UPI or Internet Banking), choosing PayTM, and entering the PayTM UPI ID -- if it is valid then entering the OTP, entering the among, making the payment, and finalizing the purchase. If they choose Internet Banking, they have to select the bank, enter the username/password, and validate if the details are correct. In simpler words, a website flowchart (also known as a sitemap) maps out the structure and complexity of any current or future website.
