Webhook packet question

Hi,

I’m looking at how larger packages of webhook data are split up:
https://docs.particle.io/guide/tools-and-features/webhooks/#handling-web-responses

I see that the hook responses packets can be identified by number. For example
hook-response/get_weather/0 , hook-response/get_weather/1, etc.

I’m wondering if there is a way to read the total number of packets and parse only the latest or final one?

Thanks for any help.
