Is it okay to use client credentials grant type for authentication of a WEB API going to be consumed by SailPoint(IAM)

[bollu srikanth]

I have an old windows application written in VB.NET with SQL server backend. Currently the new user additions, deletion, adding entitlements etc. are managed by an old approval workflow system. After getting approvals, the user details and entitlements are inserted in to the SQL server database table manually.

I am trying to integrate this application with the SailPoint's Identity and access management. So the new user addition, deletion update and adding entitlements etc will be done through Sailpoint. For this, I would require to create a WEB API which can be called by Sailpoint and expose the functionalities(add user/delete user/add entitlements). The only consumer to this API is SailPoint.
