Hi @chandramohans27,
What do you mean by making api call ?
As describe here : Manager Correlation Rule | SailPoint Developer Community
Manager correlation rule is cloud rule. That mean it’s deployed by Sailpoint.
Once you develop your rule, you can check it with rule validator https://community.sailpoint.com/t5/Professional-Services/IdentityNow-Rule-Validator/ta-p/166116
And after that, you send it to sailpoint support for deployment in your tenant.
After deployment sailpoint will give you the id of your rule or you can retrieve it by using sp-config as describe here : GET /api/rule/list - Identity Security Cloud (ISC) / Non-Public API Deprecations - SailPoint Developer Community. The existing endpoint for retrieve your tenant rule list is deprecated and the remplacement is to use spconfig.
And in final step with patch operation endpoint update-source | SailPoint Developer Community you can update your source by attaching your manager correlation rule :
