Create label webhook - clarification on packages[].name field

In the webhook documentation, I see that the “name” field in the response echoes back the same value of the same-named field in the request. During testing, we noticed that if we don’t echo back this field, the ShipHero user receives the following error: Package name response does not match the expected format: ‘ ’

I don’t see documentation specific to this field, or behaviours, and I want to know the following:

  1. Is echoing back the exact value (e.g., Package 1) the expected and required behavior for successful package matching?
  2. Should we always expect the “Package #” convention?
  3. Is there any additional significance to this field we should be aware of?

Hoping for clarity on this one. Thanks.
