Hi,
I have created an Environment Variable in my Power App Solution and I want to access the value of the variable using the Web API in a Web Resource with JavaScript.
Could this done using XRM in Javascript ?
Thanks

Hello Rory,
Generally speaking "Environment Variable" is 2 entities in CDS that are available through api.
You should query entities environmentvariabledefinition (to apply the filter by variable name) and environmentvariablevalue to get the value. Generally speaking following FetchXml should bring you what you need:
<fetch> <entity name="environmentvariabledefinition" > <filter> <condition attribute="schemaname" operator="eq" value="test" /> </filter> <link-entity name="environmentvariablevalue" from="environmentvariabledefinitionid" to="environmentvariabledefinitionid" > <attribute name="value" /> </link-entity> </entity> </fetch>
An improvement on the above is to make it an outer join and to also return the DefaultValue from the environment definition - then you have the ability to cater for if the environment variable is not set in an environment.
As the previous users mentioned, you can. A clean way if you want to avoid fetchXML is with the out-of-the-box client web api script, retrieveRecord.
Xrm.WebApi.retrieveRecord("environmentvariablevalue", <GUID>, "?$select=value").then(successCallback, errorCallback);
Note: the GUID of the environment variable value will be the same in the different environments if you imported the variable with a solution.

Hope this helps!
