Webhook to create issue using Automation

[__ PowerUps]

I am trying to do an Automation in JiraService Desk

* Incoming Webhook
* Create ServiceDesk Customer
* Create Issue

Here is what happens:

1) POST attempt #1 => Customer is created (but fails on Create issue, because it says the reporter is invalid

2) POST attempt #2 (using same data) => Issue is created.

So when a new customer is created in step 2 of the automation, how do I reference (or wait) the newly created customer in  step 3 of the automation.
