POST
Create an endpoint
Creates a webhook endpoint — or a Slack/Discord notification endpoint, see type below. For a webhook, the response includes a secret (prefixed whsec_) shown only once — store it to verify signatures. Slack/Discord endpoints have no secret.
string
required
A label for the endpoint (1–100 chars).
string
default:"webhook"
webhook, slack, or discord (forward relays to a mailbox instead — see forwarding). Slack/Discord post a formatted notification to url (that channel’s incoming-webhook URL) instead of raw JSON, and aren’t signed.
string
required
Delivery URL (http/https). Must resolve to a public host — private and internal addresses are rejected. For slack/discord, must also match that provider’s incoming-webhook host.
object
Up to 10 custom headers sent with every delivery. Reserved headers (Content-Type, X-Inboundr-*, X-Inbound-*, …) can’t be overridden.
integer
default:"10"
Per-request timeout, 1–30 seconds.
integer
default:"5"
Total attempts (first + retries), 1–10.
Copy the secret now — it’s shown only at creation.
