How to send the newly created salesforce id to a Custom APEX action as a parameter

Thanks Pete. I dont know for some reason the vale is never getting updated in the column . I have even run an save model after the snippet to make sure the data is saved.

I have to send the newly created id to the custom apex action. I tried too many way and thought that I would update to a field and send the field value but No luck. Any insights would help me a lot. Thanks in Advance
