# Webhooks and status polling Canonical HTML: https://spoolis.com/docs/webhooks. This page is also available in machine-readable Markdown. Spoolis does not send outbound webhooks today. Poll supported resources or use the MCP tools for current state. ## Current webhook support Spoolis has no outbound webhooks today. ## Poll current state Poll `GET /api/v1/receipts/{id}/status` for the optional online status of an Outcome Receipt. Poll `GET /api/v1/spools/{id}` for the current canonical Spool state. One-call verification responses include `receipt_url`, a human-readable URL for the result. ## MCP alternatives The MCP server exposes tools for one-call verification, Spool retrieval, lifecycle actions, evidence submission, verification, and event reading. See the [MCP server guide](/docs/mcp).
