Sent once per measurement deleted. The payload is the measurement as it was before deletion.

Payload

The payload of this webhook request is an object.

idstringRequiredformat: "^whe_[a-zA-Z0-9]{10,22}$"

Unique identifier for a webhook event. A retried delivery carries the same identifier, so use it to discard duplicates.

eventenumRequired

The event that occurred.

Allowed values:

versionenumRequired

A released version of the public API. Each OAuth client is registered against one version, which determines the response shape it receives.

Allowed values:

created_atdatetimeRequired

UTC timestamp with microsecond precision, always suffixed with Z, in the form yyyy-MM-ddTHH:mm:ss.SSSSSSZ.

payloadobjectRequired

A set of readings taken on an animal on a single day, together with any values derived from them. Which readings and calculations a measurement carries is determined by your team’s measurement settings; a measurement that recorded a reading no longer configured for your team omits it.

client_idstringOptionalformat: "uuid"

The OAuth client whose API request caused the event. Omitted when the event did not originate from an API request, and on events that never carry it.

Response

2XX

Any 2xx status acknowledges the delivery, which is then not retried. The response body is ignored.
