secret is no longer accepted

What changed

Usually ignored rather than rejected, so the call succeeds and does something subtly different.

Affects secret on PUT /accounts/{account_id}/alerting/v3/destinations/webhooks/{webhook_id}. Grep for it: nothing else will tell you.

Who is affected

Code that sends PUT /accounts/{account_id}/alerting/v3/destinations/webhooks/{webhook_id} (secret).

Before and after

Code that breaks

await client.post("/accounts/{account_id}/alerting/v3/destinations/webhooks/{webhook_id}", {
  // secret is now ignored, not rejected
  secret: value,
});

Based on Cloudflare’s published API specification. How severity is decided.
