Get date of last successful job run?

I have a single step job that executes a stored procedure. I would like get the date of the last successful job execution time so that I can just update a delta instead of the whole set of data.

Right now I have the job setup to run once every day, so I have a default parameter that if it's null I set it to GETDATE() - 1 so I'm still updating a delta but what I'd like to do is set the date to the last successful execution of the job.

exec dbo.usp_UpdateFrom @LastSuccessfulExecutionTime
 

Current procedure is something like

CREATE PROCEDURE dbo.usp_UpdateFrom
     @FromDate datetime = NULL --would like to pass last successful execution time of the job
 AS
     IF @FromDate IS NULL
         SET @FromDate = GETDATE() - 1
 
     -- do stuff
 END
