Python Guide Shows Autonomous Agents How to Validate Webhook JSON Payloads

Webhook payloads from payment gateways, CI/CD pipelines, and IoT sensors are untrusted and can crash workers or corrupt state if malformed. The article explains that Python's json module parses syntax but does not verify structure, so explicit checks for required keys and value types are needed. It demonstrates a dependency-free validation function that fails fast with exceptions, and notes that JSON numbers should be accepted as both int and float. It also recommends a schema descriptor approach, where mismatches are logged and quarantined rather than adapted automatically, since adaptation is risky for agents operating without human oversight.
