WEBHOOK

Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Headers

​
X-Orb-Signature
string
required

v1= followed by the hex HMAC-SHA256 of v1:{X-Orb-Timestamp}:{raw request body}, keyed by the endpoint's webhook secret. The header may carry several space-separated signatures during a secret rotation; a receiver accepts the delivery when any v1 signature matches. Compare in constant time, and sign the bytes as received rather than a re-serialized body.

​
X-Orb-Timestamp
string<date-time>
required

When the delivery was signed, ISO 8601 to milliseconds. It is part of the signed message, so a receiver must reject timestamps outside its tolerance to stop replays.

Body

application/json

Issued when metric events are dropped by watermark threshold.

​
id
string
required

The ID of this webhook event.

​
created_at
string<date-time>
required

The time at which this event was created, to the second.

​
type
enum<string>
required

The event this payload describes.

Available options:
metric.events_dropped_by_watermark
​
properties
DroppedByWatermarkThresholdWebhookEventProperties · object
required

window_start and window_end are ISO-8601 strings rather than datetimes: the untyped message called .isoformat() on them, so they keep microseconds where the webhook JSON provider would have truncated them.

Response

2XX

Any 2xx acknowledges receipt.
