Sending an HTTP request to SharePoint

This is my guide for patching SharePoint items using the SharePoint REST API. All code can be copied and pasted into the body. Method, Uri and Headers will need to be different depending on whether you’re creating or updating an item. All Methods, Uri and Headers are provided below.

You can get the sp.listitem code from _api/web/lists/GetByTitle('<ListName>')

Get ssplist from https://<Tenant>.sharepoint.com/sites/<ListName>/_api/web/lists/getbytitle('<list title>')/fields?$filter=InternalName eq '<managed metadata name>'
