概要

Register webhook plan downgraded

POST/api/v1/register_webhook_plan_downgraded
Features

Register a webhook for the 'plan_downgraded' event (BUSINESS) — the direct call for 'notify us when…', 'alert me if…', 'ping our channel when…' about this event. Fires when the workspace owner downgrades plan. Delivery is an asynchronous HTTP POST. A Slack (hooks.slack.com) or Discord (discord.com/api/webhooks) incoming-webhook URL is recognised by its host and the message shaped for that platform — paste it as-is; any other URL receives the signed JSON envelope (HMAC-SHA256 in X-Docsbook-Signature-256, event type in X-Docsbook-Event). Below the BUSINESS plan the call returns PLAN_RESTRICTION naming the tier — no pre-check needed.

Price — $0.00001 per call (twice what serving it costs us), charged to the workspace balance, the same as over MCP.

Also reachable by name at POST /api/v1/tools/register_webhook_plan_downgraded.

Input3
Authorizationheaderrequired
Your API key, sent as Authorization: Bearer dbk_YOUR_API_KEY.Sent from your browser straight to the API — never to Docsbook, never stored.
urlstring · body
HTTPS endpoint to receive POST callbacks
secretstring · body
Optional shared secret (>=16 chars). One is generated if omitted.
auth_headerstring · body
Optional Authorization header value sent verbatim on delivery, e.g. 'Bearer sk-…' for endpoints that require auth (Claude Code routine fire URLs).
Output3
okboolean
Whether the tool itself succeeded. A tool that ran and refused — an exhausted balance, a plan restriction, a bad argument — answers 200 with ok: false: the call was made and billed, and that refusal is its answer.
resultobject
The tool's own JSON answer, already parsed — not a string to parse a second time.
