I'm integrating with Transparent Redirect, when the user submits the credit card information to PayPal site, it returns a redirect page, which looks like this: <body>
<div align="left">
<div id="payflow-link">
<p class="note"><br/></p>
<!-- Logo/Display Name -->
<h1>
</h1>
<!-- End: Logo/Display Name -->
<p class="note"><br/></p>
<form name="redirectForm" action="<callback confirmation url>"
method="post" style="display: none">
<input type="hidden" name="SECURETOKEN" value="<token>"/>
<input type="hidden" name="COUNTRYTOSHIP" value="US"/>
<input type="hidden" name="AVSDATA" value="XXN"/>
<input type="hidden" name="COUNTRY" value="US"/>
<input type="hidden" name="AMT" value="123.45"/>
<input type="hidden" name="ACCT" value="1111"/>
<input type="hidden" name="AUTHCODE" value="764PNI"/>
<input type="hidden" name="VISACARDLEVEL" value="12"/>
<input type="hidden" name="PNREF" value="A10AA4BFFD0B"/>
<input type="hidden" name="TRXTYPE" value="S"/>
<input type="hidden" name="RESULT" value="0"/>
<input type="hidden" name="SECURETOKENID" value="<token id>"/>
<input type="hidden" name="POSTFPSMSG" value="No Rules Triggered"/>
<input type="hidden" name="SHIPTOCOUNTRY" value="US"/>
<input type="hidden" name="BILLTOCOUNTRY" value="US"/>
<input type="hidden" name="EXPDATE" value="1218"/>
<input type="hidden" name="RESPMSG" value="Approved"/>
<input type="hidden" name="TRANSTIME" value="2017-05-26 09:35:05"/>
<input type="hidden" name="HOSTCODE" value="A"/>
<input type="hidden" name="CARDTYPE" value="0"/>
<input type="hidden" name="PREFPSMSG" value="No Rules Triggered"/>
</form>
<script language="javascript">
document.redirectForm.submit();
</script>
</div>
</div>
</div>
</body>
</html> To have a better user experience, I would like this page to show something, instead of being a blank page, because it might confuse customers if my callback confirmation url takes more than a couple of seconds to load. I see that there seems to be a placeholder for Logo/Display Name and maybe even a note, but I wasn't able to find how to customize this page in PayPal's documentation. Is there a way? Thanks
