Run Workflows using CRM 365 Web Api

Hi all, Today I am going to post a sample code you can use to run a workflow in CRM 365 using the new Web Api.

The function takes three parameters in input: the workflow Guid, the record Guid and a boolean to tell the Web Api whether or not to run the workflow synchronously; true = asynchronously which is the default behaviour, false = synchronously.
The Workflow should be set up to be run either as a child or On demand Workflow otherwise you'll get an error.

var _runWorkflow = function (workflowId, recordId) {

        var parameters = {};
        parameters.EntityId = recordId;

        var req = new XMLHttpRequest();
        req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/workflows(" + workflowId + ")/Microsoft.Dynamics.CRM.ExecuteWorkflow", false);
        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) {
                    var results = JSON.parse(this.response);
                } else {
                    //Xrm.Utility.alertDialog(this.statusText);
                }
            }
        };
        req.send(JSON.stringify(parameters));
    }

Here is an example of how to call the function above after saving the record via javascript:

Xrm.Page.data.save().then(
            function () {
                var entityType = Xrm.Page.data.entity.getEntityName();
                var recordId = Xrm.Page.data.entity.getId();

                var wfGuid = LDA.Functions.Common.GetWorkflowGuid(entityType);

                if (wfGuid == "na") return;

                LDA.Functions.Common.RunWorkflow(wfGuid, recordId.replace("}", "").replace("{", ""));
             
                Xrm.Page.data.refresh(false);
            },
            function () {
                //handle errors
            }
        );



That was it, very simple and straight forward, hope it helps to get you started with the new CRM 365 Web Api. If you have any questions leave a comment and I'll get back to you ASAP.
