Unable to retrieve FirstName and LastName in Before Operation Rule for Web Services

@sita_ram Refer below post:

Add/Remove Entitlement operation $plan placeholder issues - Identity Security Cloud (ISC) / ISC Discussion and Questions - SailPoint Developer Community

Try this:

  1. Parent endPoint - First get the account details and map those in response mapping
  2. Child endPoint - Get the values from Parent response and pass it to body.

Also to your point why you are not getting values using $paln.firstName$ etc.

you can only get the requested attribute from the plan.

For e.g. in this case you are trying to remove the entitlement, so you will only get which role is getting removed and the nativeIdentity in the plan not others.

For Create Operation you are getting all the required values from Create Profile and they are there in the provisioning plan.
