Update Data Item

Updates an item in a collection.

Call this method when you want to replace an existing item's payload and expect the item to already exist. For different behavior, you can call:

• Patch Data Item to make partial field changes that keep the rest of the payload unchanged.
• Save Data Item for upsert behavior, meaning to create the item if it doesn't exist and update it if it does.

This method replaces the data item's existing data with the payload provided in dataItem.data in the request.

To update an item, you need to specify an item ID and a collection ID. If an item is found in the specified collection with the specified ID, that item is updated. If the collection doesn't contain an item with that ID, the request fails.

When an item is updated, its data._updatedDate field is changed to the current date and time.
