} This change does not have a general retry guarantee. If the response is unclear, read the affected resource before trying again. Follow Retry-After waiting times and request new sign-in or action codes when they expire.
Replace demo IDs, timestamps and placeholders with your own values. For a retry, keep the same IDs, time and content. These examples do not run requests on this page.
Keep login links, codes, cookies and keys private. Do not print them in logs or share them in support requests.

GET Read HTTP header names without their secret valuesReturns header names and whether values are configured; it never returns secret values. Use config_revision when making concurrent changes.
PUT Store or remove encrypted HTTP headersAt most eight stored headers are allowed. Values are encrypted with AES-256-GCM and bound to account, monitor, origin and header name. Use explicit removal instead of an empty replacement secret.
DELETE Permanently delete a monitorOnly the workspace owner may permanently delete a monitor. First request a five-minute configuration-bound preview, then send preview_id, confirm_deletion: true and an Idempotency-Key. Unconfirmed legacy archive requests are rejected. The monitor is immediately blocked; a durable job removes all its database, archive and cache data and cleans linked displays. Read the job until complete; paused jobs show a technical error and retry automatically. Daily quotas and security counters remain unchanged. Previously delivered messages and downloaded files cannot be recalled.
