How do I validate cardsV2 payload structure before sending Google Chat alerts?▼

Validating cardsV2 payload structure before sending Google Chat alerts involves checking the constructed headers, sections, and widgets against reference models. This ensures the payload is correctly formatted before performing the HTTP delivery.

What is the best way to build structured error alerts for Google Chat from Python?▼
