@fm_skeller
I am using below javascript code
function triggerOnDemandWorkflow() {
console.log("Inside Function");
var entityId = document.getElementById('EntityFormView_EntityID');
var entity = {
"EntityId": entityId.value
};
console.log(entityId.value);

var WorkflowId = "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXX";

fetch(
"https://oooooo.api.crm.dynamics.com/api/data/v9.2/workflows(" + WorkflowId + ")/Microsoft.Dynamics.CRM.ExecuteWorkflow",
{
body: "{\"EntityId\":\"" + entityId.value + "\"}",
credentials: "same-origin",
headers: {
"Accept": "application/json",
"Content-Type": "application/json; charset=utf-8",
"OData-MaxVersion": "4.0",
"OData-Version": "4.0"
},
method: "POST"
})
.then(response => console.log("Success:", response))
.catch(error => console.error("Error:", error));
}

and this is the error which I am getting on execution above function on button click

@Pragatij the way you are trying to call the workflow won't work. You cannot access the CRM webapi from the portal.
From power pages, you can call a workflow like this:
var url = "/_services/execute-workflow/<your website id>"; var data = {}; var workflowReference = {}; workflowReference.LogicalName = "workflow"; workflowReference.Id = workflowid; data.workflow = workflowReference; var entityReference = {}; entityReference.LogicalName = entityName; entityReference.Id = id; data.entity = entityReference; var json = JSON.stringify(data); shell.ajaxSafePost({ type: "POST", contentType: "application/json", url: url, data: json }).done(function() { //workflow executed successfully }).fail(function(e) { //workflow failed for some reason })

Can it be a power automate instead? There is native support for calling those now: https://youtu.be/JS16v3xBLFU
