You can update your items using JSON under the bigcommercecustomfields header or you can update the custom fields using the SureDone custom field headers you use to update details for other channels. Similar to Amazon, you can map you SureDone custom fields to the Big Commerce ones you created. If you are opting to edit them using SureDone custom field headers, then make sure you remove the value in bigcommercecustomfields from your CSV since JSON takes precedence.
