Background

Roadmap reference: ROADMAP.md > P3 > Webhook/notification support

Batch jobs can run for several minutes and users must poll for results. Webhook or notification support would allow integrating SPARC results into team workflows (Slack, Discord, email).

What to do

  1. Add a webhooks table (url, events, secret, enabled).
  2. Implement a POST /webhooks registration endpoint and a DELETE /webhooks/{id} endpoint.
  3. After a batch job completes (or an innovation score changes significantly), POST a signed JSON payload to all registered webhook URLs.
  4. Sign the payload with HMAC-SHA256 using the webhook secret and include it in an X-SPARC-Signature header.
  5. Support at minimum the events: job.complete, job.failed, score.changed.
  6. Add a test endpoint POST /webhooks/{id}/test that sends a sample payload.

Acceptance criteria

  • Registering a webhook URL causes a POST to be sent when a job completes.
  • The payload is HMAC-signed and the signature can be verified with the registered secret.
  • Failed webhook deliveries are logged with the HTTP status code returned.

Closing: already implemented in main. webhooks.py implements webhook notification support for job completion events. Configurable via WEBHOOK_URLS env var.
