Hi Rajkiran,

I found this article link that may helps you.

Hi Rajkiran,

I'm assuming that you're looking to trigger these actions outside of your OutSystems environment hence asking for an API (Otherwise the suggestion below will still be applicable just without exposing that functionality in a custom API) .

For your first point, there are a couple options:

1. Inactivating the user instead of deleting them (by using the User_Update method and passing in False in the Is_Active field) - Inactive users are excluded from User license limits. 
2. OutSystems allows you to create & expose your own custom API. This means that you can create a custom API which deletes all roles from a user (by filtering the User_Role Entity in the System module by the UserId and deleting those records) first and then call the User_DeleteIfNoRoles action in the same flow. Given the sensitivity of data at hand, ensure that you have configured your API Authentication adequately - see more here.

For your second point, Lifetime's v2 API has a user endpoint however the deletion of users is not within the scope of its actions. 

One last thing to note is that if OutSystems doesn't expose the exact functionality you're looking for ootb than there might be a good reason for it. I'd recommend researching OutSystem's suggestions and security best practices on the matter before delving into solution mode :)

Hi Rajkiran, 

In addtion to Ossama's reply. Instead of User_Role Entity you should refer to User_Effective_Role Entity, Because it's include the roles thease are inherit from Groups. 

For question #2, Is "User from Outsystems lifetime" means IT user? It's very different to end user, as Ossama said,

You should consider the security best practices. Is it really need to delete IT user progmactlly?
