Integration and Testing

We are having the same issue as in this post: https://community.developer.authorize.net/t5/Integration-and-Testing/AUthorize-net-hosted-payment-pa...

From reading that post, we have tried applying the content-security-policy via web.config file (asp.net/IIS) is not working. We are passing a paymentProfileId in the token.

• We are still seeing the error in the console.
  • Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('our domain') does not match the recipient window's origin ('auth.net domain')
• The payment gets cut off and is not the correct size so you cannot see all of the fields.
• The purchase window does not close after a purchase.

Example of web.config:

<httpProtocol>
<customHeaders>
<add name="Content-Security-Policy" value="frame-ancestors 'self' https://localhost:44300 *.ourdomain.com *.authorize.net" />
</customHeaders>
</httpProtocol>

We have even tried with the Content-Security-Policy-Report-Only but still no luck, it acts the same. 

What can we do when the content-security-policy is not working?

Hello,

Try the following in your Web.config

<system.webServer>
  <httpProtocol>
<customHeaders>
<add name="Content-Security-Policy" value="frame-ancestors 'self' *.YOUR_WEBSITE.com *.authorize.net;" />
</customHeaders>
</httpProtocol>
</system.webServer>

I'm pretty sure we've tried that but let me give it another go and post back, thank you for the suggestion!

No dice, still does not work. I find it odd that it doesn't work with the report-only option. Does anyone know of a setting within IIS that would be overriding the web.config?

Sometimes this error is the result of a target window that has not finished loading.

The basic syntax to check that the target frame has loaded would be :

const iframe = document.getElementById("pay_frame");
iframe.addEventListener("load", function() {

// Continue to display the content ... 
});

For IIS, to disable inheritance in child applications, wrap the configuration block in a:

<location path="." inheritInChildApplications="false">

<system.webServer>
  <httpProtocol>
<customHeaders>
<add name="Content-Security-Policy" value="frame-ancestors 'self' *.YOUR_WEBSITE.com *.authorize.net;" />
</customHeaders>
</httpProtocol>
</system.webServer>

</location>
