Hi @mike_reasi, The list of [business classifications](https://docs.dwolla.com/#list-business-classifications) will contain an `_embedded` list of industry classifications. You’ll want to make sure you’re selecting an industry classification Id and not a Business Classification Id. For example, if the business classification is “Food retail and service” then you’ll want to select an industry classification ID within that like “Restaurant” with an ID of `9ed3f673-7d6f-11e3-adb1-5404a6144203`. It’s recommended to cache the list of industry classification ids used on your platform vs. calling the API each time or storing the full list of Ids.

Hope this helps, please let us know if you continue to run into issues!
