List webhook endpoints
Every endpoint of the API key's environment, oldest first. Webhook endpoints belong to the API key's own environment: a coss_test_… key only ever sees sandbox endpoints, and a coss_live_… key only production ones.
bearerAuthAuthorizationBearer <token>A secret API key from the dashboard: coss_live_… for production environments, coss_test_… for sandbox environments.
Coss-Version?"2026-10-10"The API version (a date) to use for this request. Defaults to your organization's version, pinned to the latest one when it first used the API and upgraded from the dashboard. The SDK always sends the version it was built for.
"2026-10-10"The environment's webhook endpoints.

The endpoint's delivery log, newest first: one delivery per event sent to it, with every HTTP attempt and the payload as sent. Pass the last `id` as `after` to get the next page while `has_more` is true. Deleting the endpoint deletes its log.
Retry a delivery POST
Queues a finished delivery (`succeeded` or `failed`) for one more attempt, made within seconds, signed with the endpoint's current secret and sent to its current URL. A delivery that is still `pending` is returned unchanged: it is already scheduled for `next_attempt_at` (automatic retries stop after 8 attempts).
