Authorizations

Authorization
string
header
required

An OAuth 2.0 bearer token, sent as Authorization: Bearer <token>. This is the recommended way to authenticate.

Get one by exchanging a service account's access key pair at POST /v1/oauth/token with grant_type=client_credentials. It is the standard client-credentials grant, so any OAuth-aware library will obtain and refresh it for you.

Tokens last an hour by default. The same access key pair is separately your AWS SigV4 credential for the S3-compatible object endpoint, which speaks nothing else.

Path Parameters

id
string<uuid>
required

Immutable alert UUID. Names and CRNs are not accepted in identity paths; use list filters.

Body

application/json

Only supplied fields change. The expression is replaced as a whole. Null is allowed only for silenced_until. Name is immutable. Rule edits and enable changes reset evaluation; edits discard events queued for the previous configuration.

topic
string

Required same-account, same-region notification topic reference: UUID, canonical CRN or exact name, classified by syntax. Multiple alerts may share a topic. Binding requires notifications:Publish and respects explicit topic-policy denies.

Available options:

threshold
number<double>
window_seconds
integer

Whole-minute window. Evaluated every minute against the last complete UTC-aligned window.

Required range: 60 <= x <= 3600Must be a multiple of 60
for_seconds
integer

Continuous breach duration before firing; 0 fires immediately. Missing data, query failures and scheduling gaps reset a pending duration.

Required range: 0 <= x <= 86400Must be a multiple of 60
enabled
boolean
default:true
silenced_until
string<date-time> | null

Mute notifications until this instant (at most 30 days ahead). Evaluation continues; null removes silence. An active alert notifies on the next evaluation after silence expires.
