Hi @Cody_Eddings!
We actually have a Postman Collection filled with examples. All you have to do is fill in the blanks (token, customerID, transferID, etc.)
The create an unverified customer
post request can be found in the customers
folder.
There is also a good post on how to use our postman collection here
Also make sure you are using the actual token for your bearer token. You can create this token in your sandbox applications tab through the create token
button or in the postman collection itself in the OAuth folder
