webhooker/TODO.md

Workflow

• branch (from main)
• do the work in Next Step
• move Next Step to the top of Completed Steps
• move the top item of Future Steps into Next Step
• commit (TODO.md changes in the same commit as the work)
• merge to main if the branch is not protected, otherwise open a PR
• push

Status

pre-1.0. No git tags exist. main (afe88c6) is a working webhook proxy with auth, CSRF/SSRF protections, login rate limiting, Slack target, policy compliance (#6), and pinned lint tooling (#55). Note: TODO.md was deliberately deleted from this repo in f9a9569 (2026-03-01, #6); its content was folded into the README TODO section, which this draft reconstructs as of 2026-07-06.

Next Step

Implement automatic event retention cleanup based on retention_days: a periodic maintenance job that deletes Events, Deliveries, and DeliveryResults older than the parent webhook's retention_days from each per-webhook event database. The field exists on the Webhook model and the README promises the behavior, but nothing enforces it, so event databases currently grow without bound.

Completed Steps

• 2026-03-25 pin golangci-lint Docker image for linting (#55)
• 2026-03-18 CSRF middleware detects TLS per-request, fixing login over plain HTTP and behind reverse proxies (#54)
• 2026-03-17 root path redirects based on auth state (#52)
• 2026-03-17 CSRF protection, SSRF prevention for HTTP delivery targets with DNS rebinding defense, and per-IP login rate limiting (#42)
• 2026-03-17 Slack target type for incoming webhook notifications (#47)
• 2026-03-17 Dockerfile absolute paths and static linking (#49); absolute dev DATA_DIR default and clarified env docs (#46)
• 2026-03-05 security headers middleware, session regeneration on login, request body size limits (#41)
• 2026-03-04 tests for delivery, middleware, and session packages (#32); removed globals.Buildarch (#31)
• 2026-03-04 1.0 MVP merge: Webhook/Entrypoint/Target rename, core delivery engine with bounded worker pool and circuit breaker, parallel fan-out, per-webhook event databases, management UI (#16)
• 2026-03-01 repo brought to REPO_POLICIES standards; TODO.md folded into README (#6)

Future Steps

• Manual event redelivery from the web UI (replay is a core promised capability in the README rationale)
• Delivery status and retry management UI
• Per-webhook rate limiting in the receiver handler (per-webhook config plus handler enforcement; global limits must not apply to receiver endpoints)
• Webhook signature verification for GitHub and Stripe HMAC formats
• API key authentication for programmatic access (APIKey model exists; Bearer token middleware does not)
• REST API v1
  • CRUD for webhooks, entrypoints, targets
  • event viewing and filtering endpoints
  • event redelivery endpoint
  • OpenAPI specification
• Analytics dashboard: success rates, response times, volume
• Session expiration tuning and a remember-me option
• Password change and reset flow
• Later, nice to have
  • email delivery target type
  • SNS and S3 delivery targets
  • data transformations (e.g. webhook to Slack message formatting)
  • JSONL file delivery with periodic S3 upload
  • webhook event search and filtering
  • multi-user with role-based access control
