Multiple Customizations

If you have multiple importers in your app and want each one to use different customizations, you can create a customization for each importer on the Customizations page and then use their customization keys with the SDK to customize each importer.

First, "Create a copy" of your initial customization.

Then, set the settings that you want to use for your second importer.

Finally, use the "Customization key" that you specified as the customizationKey in the SDK.
