How to Call Action from WebResource using Web Api

Implementation Steps:

1. Create a Action ( find my blog here on how to create Action)

2. I have Created an action without any input Parameters

3. Once the Action is Created, Navigate to Settings --> Customization --> Customize the System --> Click Web Resource

4. Click New and Create a New Web Resource with Below Code

var req = {};
req.getMetadata = function () {
 return {
 boundParameter: null,
 operationType: 0,
 operationName: "new_AccountAction"
 };
};
 
Xrm.WebApi.online.execute(req).then( 
 function (data) { 
 var e = data; 
 debugger; 
 }, 
 function (error) { 
 debugger; 
 var errMsg = error.message; 
 }
);

5. That's it.

Now Call this function from OnLoad Or OnSave or OnChange from Account Level.
