Getting Started
There are few basic requirements to get started:
Web Hosting. The merchant must have a website which is hosted and publicly available. The Cascading Style Sheet and company logo are hosted by the merchant.
HTML or Plaintext plain text editor. Form elements will need to be added to existing or new HTML, with either a HTML or Plaintext plan text editor.
Merchant Account. A merchant account is required to begin processing live transactions.
Submit Final Amount Only. ME Hosted Checkout will only process the amount sent in the transaction_amount field. Shipping charges, local tax, etc. will need to be accommodated before the transaction is submitted.
Transaction Flow
MerchantE’s Hosted Payments will guide your customers through the checkout process to ensure their experience is as simple as possible. When your customer is redirected to your payment page, your customer will have the option to checkout as a guest, create a payment account, or they can log in to make a payment. The checkout experience between guest checkout and a payment account holder checkout is slightly different. Customers that “Checkout as Guest” have a limited view of Hosted Payments.
...
A customer is on a merchant’s e-Commerce website and clicks Checkout.
The customer is redirected to the MerchantE Hosted Payment Page
The customer enters their payment details and submits the payment.
If the payment is approved, the customer is presented with a payment receipt and has the option to return to the merchant’s website.
If the payment is declined, the customer is presented with a generic payment decline and advised to reach out to the issuer for more details.
Integration with Website
The following are the recommended steps to integrate ME’s Hosted Payments into an e-Commerce website.
