Docs : SDK : updateItem

updateItem lets you modify an existing item in a user's database. This API will return a promise that gets resolved once the item has been durably updated in the database.

    userbase.updateItem({ databaseName, item, itemId })
      .then(() => {
        // item updated
      })
      .catch((e) => console.error(e))
