Constituent Name Standardization

I hope you’re all doing well. I’m reaching out for some guidance on a Power Automate flow I’m developing to help manage constituent data in Raiser's Edge NXT.

The flow’s purpose is to standardize data by checking for and correcting any improperly formatted names and addresses. Specifically, I want to retrieve fields like First Name, Last Name, Middle Name, Preferred Name, and Address, identify cases where they are in all lowercase or uppercase (e.g., “john doe” or “JOHN DOE”), and then update them to proper case format (e.g., “John Doe”).

To accomplish this, I need to access each constituent’s specific record through the API. If you could help me identify the appropriate endpoint or provide any documentation on accessing constituent-specific details, I would really appreciate it.
