Update the AI Security for Apps custom topics of a zone.

PUT/zones/{zone_id}/ai-security/custom-topics

Update the custom topic list of the zone, overwriting it entirely with the topics in the request, so include every topic you want to keep. Changes can take up to a minute to propagate.

Each entry has a label, used to reference the topic in rule expressions and analytics, and a topic description, which the classifier scores prompts against while AI Security for Apps is enabled. The following rules apply:

A zone can hold at most 20 topics.
label must be 2–20 characters, using only lowercase letters (a–z), digits (0–9), and hyphens.
topic must be 2–50 printable ASCII characters.
Labels must be unique within the zone, and so must topic descriptions.
