Patch operation on Business Partner API through cloud sdk

Hi all,

I'm trying to perform patch operation on Business partner through cloud sdk (java) but it is failing to perform the operation.

I also tried to perform the same operation on BP through postman and getting the following error

CSRF token validation failed

I have following questions:

1. How to perform patch operation through cloud sdk or postman?

2. How we'll get the csrf token and pass it to the patch call through cloud sdk or postman?
