Thanks @shreya, those tips are helpful! I still think it would be nice if the API returned the exact value of the businessType back that was used rather than the ambiguity between llc, corporation or partnership based on the presence of the controller object, but I guess I can work around it with my application database.
Edit: This topic can be locked or deleted now that we can pass a correlationId when creating Customers - I can easily handle this type of stuff with my application’s database now instead. Thank you.
