Help ref# 77342

If you get a CORS issue like the image below

It could be an issue with your web.config in that it is missing the CORS xml code

On your CRM server open "custompages/sagecrmws/web.config" and search for the "<system.webServer>" section.

You should see a number of "Access-Control-Allow-..." options within the "<system.webServer>" section.

 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="*" />
       <add name="Access-Control-Allow-Headers" value="*" />
       <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE,PATCH,OPTIONS" />
       <add name="Access-Control-Allow-Credentials" value="true" />
       <add name="Access-Control-Allow-Private-Network" value="true" />
     </customHeaders>
   </httpProtocol>

....leave any code in between thats there already...and do not copy this line in  :)

 </system.webServer>

If you do see it check that

   "Access-Control-Allow-Headers" 

has the value

   "Content-type, App-Mode, App-Capacitor-Platform, App-Connector, App-Container, App-version, Authorization" 

set

If you do not see it then add it in.

Add in the section

   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="*" />
       <add name="Access-Control-Allow-Headers" value="Content-type, App-Mode, App-Capacitor-Platform, App-Connector, App-Container, App-version, Authorization" />
       <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE,PATCH,OPTIONS" />
       <add name="Access-Control-Allow-Credentials" value="true" />
       <add name="Access-Control-Allow-Private-Network" value="true" />
     </customHeaders>
   </httpProtocol>

between

 <system.webServer>

and

 </system.webServer>

then after </httpProtocol> (THIS IS THE CLOSING TAG AND NOT THE OPENING ONE)add in

   <rewrite>
     <outboundRules>
       <clear />

<rule name="AddCrossDomainHeader"> <match serverVariable="RESPONSE_Access_Control_Allow_Origin" pattern=".*" /> <conditions logicalGrouping="MatchAll">

           <add input="{HTTP_ORIGIN}"
                pattern="^(capacitor://localhost|https?://localhost(:\d+)?|https?://(.+\.)?crmtogether\.com|https?://(.+\.)?msappproxy\.net|https?://(.+\.)?mail\.google\.com)$" />
         </conditions>			  <action type="Rewrite" value="{HTTP_ORIGIN}" />

</rule> </outboundRules>

   </rewrite>

No need to restart IIS or anything. Just save the file.

• • • UPDATE: 2 July 2026 ***

Changed the pattern to fix Native Android

• • • UPDATE: 17 March 2024 ***

It appears that a wildcard header in the “Access-Control-Allow-Origin” header is no longer accepted. This causes a CORS issue and you cannot log in. We fixed this using the details above
