I was testing the scenario where we had to workaround with the plugin: prior portal Web API times 🙂 it wasn’t possible to deactivate a record from a portal with a status different from the default one. Now it’s super easy!
- I added a new inactive status for a testing purpose:

2. I updated Site Settings to include statecode and statuscode fields:

3. I added a script to update the record I wanted to deactivate:
webapi.safeAjax = safeAjax; })(window.webapi = window.webapi || {}, jQuery) if (confirm('Update?')) { alert('Thanks for confirming'); webapi.safeAjax({ type: "PATCH", url: "/_api/tk_inspections(e4c23961-61f5-ea11-a815-000d3ad20d1d)", contentType: "application/json", data: JSON.stringify({ "statecode": 1, "statuscode": 821350004 //Cancelled - custom new inactive value }), success: function (res) { alert("Yay!") } });
4. It just worked! ?

Happy days!
