I have a page set up in my model driven all to show another app in the same frame as a web resource. The url is just an iframe snippet to the app. is there a way to implement environment variables in the webresource URL to update the appid as we navigate thru the different environments?

Thank you

@ctedesco3307

you can’t directly use Environment Variables inside a static HTML web resource URL.

You can use script to load the url with dynamic value

Environment Variables cannot be directly used in a Web Resource URL because Web Resources are static and do not resolve Dataverse values at runtime.

The recommended approach is to use a JavaScript Web Resource to retrieve the Environment Variable via the Dataverse Web API and dynamically construct the iframe URL.

Alternatively, consider using a Custom Page, which natively supports environment variables and provides a more modern and maintainable solution.

Hello @ctedesco3307,

You can’t directly plug environment variables into a web resource URL, but you can work around it via using JavaScript.

Store your appId in an environment variable, then use JavaScript (Xrm.WebApi) to fetch it and set the iframe URL dynamically. That way it changes automatically across environments.

Yes, environment variables are accessible via the Web API.
