For all VPCart merchants that are currently using Authorize Net Accept Hosted payment gateway, we will need you to do an update to your web.config file.

This is required for you to make an update as recently Chrome browser is having issue in getting response from Authorize.Net if you are using this Authorize Net Accept Hosted payment gateway in your VPCart site.

NOTE: For those using Authorize Net Accept Js, you DO NOT need to do this update.

Please follow the steps below:

1. Login to your site FTP, go to httpdocs folder. Check if you have web.config file.

2. If you don't have web.config file, then please create a new file called web.config using notepad and enter this code below:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<outboundRules>
<clear />
<rule name="Add SameSite" preCondition="No SameSite">
<match serverVariable="RESPONSE_Set_Cookie" pattern=".*" negate="false" />
<action type="Rewrite" value="{R:0}; SameSite=None; Secure" />
</rule>
<preConditions>
<preCondition name="No SameSite">
<add input="{RESPONSE_Set_Cookie}" pattern="." />
<add input="{RESPONSE_Set_Cookie}" pattern="; SameSite=None; Secure" negate="true" />
</preCondition>
</preConditions>
</outboundRules>
</rewrite>
</system.webServer>
</configuration>

3. Upload the web.config file into your httpdocs folder.

4. If you already have web.config file, then please open the file with notepad or any other text editor and insert this new code before the </rewrite> :

<outboundRules>
<clear />
<rule name="Add SameSite" preCondition="No SameSite">
<match serverVariable="RESPONSE_Set_Cookie" pattern=".*" negate="false" />
<action type="Rewrite" value="{R:0}; SameSite=None; Secure" />
</rule>
<preConditions>
<preCondition name="No SameSite">
<add input="{RESPONSE_Set_Cookie}" pattern="." />
<add input="{RESPONSE_Set_Cookie}" pattern="; SameSite=None; Secure" negate="true" />
</preCondition>
</preConditions>
</outboundRules>

5. Upload the web.config into your httpdocs folder to replace your existing.
