Calling Workflow through Javascript

CALLING A DYNAMICS 365 WORKFLOW THROUGH JAVASCRIPT

In Dynamics 365, you may want to call a workflow directly from JavaScript. This can be achieved using the WebAPI.

Let’s say we have a workflow as follows, that creates a task on the account:

For the sake of the demo, we will hardcode the Workflow Id and Account Id.

Copy the Workflow Id from the URL:

Now create an account:

Get the Id of the account:

Now the code. Note we are calling Microsoft.Dynamics.CRM.ExecuteWorkflow:

var entity = {

"EntityId": "D82A5713-3C39-E811-A952-000D3A36478D" // accountId

};

var WorkflowId = "4E79CE7A-BB73-409D-9F6A-7FCBB49FFD94";

var req = new XMLHttpRequest();

req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v9.0/workflows(" + WorkflowId + ")/Microsoft.Dynamics.CRM.ExecuteWorkflow", true);

req.setRequestHeader("OData-MaxVersion", "4.0");

req.setRequestHeader("OData-Version", "4.0");

req.setRequestHeader("Accept", "application/json");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

req.onreadystatechange = function() {

if (this.readyState === 4) {

req.onreadystatechange = null;

if (this.status === 200) {

Xrm.Utility.alertDialog("Success");

} else {

Xrm.Utility.alertDialog(this.statusText);

}

}

};

req.send(JSON.stringify(entity));

Running this, we get:
