create_inbox — Makes a kept inbox on your account and returns its post_url (give this to the service that sends webhooks) and view_url (for a person to watch it live).
list_inboxes — Every open inbox on your account, busiest first, with its post_url, request count and last request time.
wait_for_request — Holds until a request lands in the inbox, then returns it in full (headers, body, provider, event, signature check).
list_requests — An inbox's requests, newest first, without bodies: id, time, method, provider, event, a plain headline and the signature result.
send_sample — Delivers a real provider webhook into the inbox, with the provider's own headers, body and signature, so you can test a handler with no provider account.
get_request — Everything caught, as it came: method, path, query, headers, the raw body (base64 when not text), sender, event, and whether its signature matched the inbox's signing secret (verified, failed, or null with no secret set), with the checks behind it.
set_inbox_answer — Changes what the inbox sends back to senders, to test how a provider handles failures: status (200, 201, 202, 204, 400, 401, 403, 404, 409, 410, 422, 429, 500, 502, 503), body as a string, delay (0, 2, 10, 30 seconds), and challenges (answer Slack, Meta and Twitch verification for you).
set_forwarding — Sends every request that lands on to your own public http or https address, exactly as it came, with retries.
