Authorizations

Authorization

string

header

required

Send Authorization: Bearer whk_…, a webhook key from the dashboard. Webhook keys belong to one network, so pick the server that matches the key. lum_ API keys are not accepted here (401).

Headers

If-Match

string

required

The ETag from GET /v1/subscriptions/{id}, for example "1" (the weak form W/"1" that some proxies produce is accepted too). A stale version returns 412; a missing header returns 428.

Pattern: ^(W/)?"[1-9][0-9]*"$

Example:

"\"1\""

Idempotency-Key

string

required

Required, 1 to 128 characters. Resending the same key within seven days returns the first test instead of sending another.

Required string length: 1 - 128

Example:

"test-0001"

Path Parameters

id

string<uuid>

required

Endpoint (subscription) ID from POST /v1/subscriptions or GET /v1/subscriptions. The example ID is a placeholder and answers 404: use your own.

Example:

"00000000-0000-4000-8000-000000000000"
