  1. Client requests Merchant payment page, which is sent to the client browser from the Merchant's website.
  2. Client enters payment data which is sent to Bluefin for processing.
  3. Bluefin replies (with HTTP 200) with a success/fail response directly to the client browser.

  1. Client requests Merchant payment page, which is sent to the client browser from the Merchant's website.
  2. Client enters payment data which is sent to Bluefin for processing.
  3. Bluefin replies (with HTTP 303) with a success/fail response to the client browser, which is redirected to the specified transparent redirect URS, which actually sends a merchant specified webpage to the client browser.
