## Which one, for what

### Inngest (B)

Good for: A TypeScript, Python or Go team that already runs agent steps as durable functions and wants a cheap, long wait for a human answer.

Ahead on:
- Reliability, 57 against 16
- Schema & documentation, 89 against 81
- Payments & pricing, 40 against 30
- Maintenance & community, 88 against 49

Also in its favour:
- Free to start without a card

Watch for: No reviewer inbox, Slack app or email, so the human side is your code

### withHuman (D)

Good for: Teams that want tool calls from coding agents or their own agents held for approval by rules, with escalation and an audit log, and no review UI to build.

Ahead on:
- Security & auth, 73 against 60

Watch for: The terms say the service is in early access, and the API document is version 0.1.0

## Verdicts

**Inngest.** Waits are durable and cost nothing while suspended, with runs up to 30 days on Free and 366 on Business. No reviewer inbox, Slack app or email, so the human side is your code.

**withHuman.** The approval API is small and carefully specified, with a public OpenAPI 3.1 document, mandatory idempotency keys and agent credentials that can never approve. The service is in early access under its own terms, with no status page, published rate limits or changelog, and the open-source repository the site links to returned 404 on 8 October 2026.

## Before you call either

### Inngest

1. Use `step.waitForSignal()` when one run waits for one answer, and `waitForEvent` only when one answer resumes many runs
2. Register the wait before you send the approval request, or check the external state first, since early events are missed
3. Use a unique approval ID per tool call and `match` on it, so parallel approvals resolve independently
4. Treat `null` or `undefined` as a timeout and decide on purpose whether that rejects, approves or escalates
5. Set an event `id` when sending the answer, so a retried send is dropped within 24 hours

### withHuman

1. Send an `Idempotency-Key` header on `POST /api/aap/v1/requests`. The call answers 400 without one
2. Read the decision with `GET /api/aap/v1/requests/{id}?wait=30s` and repeat while `status` is `pending`. `wait` is capped at 30 seconds
3. Set `timeout` between one second and seven days, and treat `expired` and `cancelled` as a refusal
4. Start an approved call within five minutes of `decided_at`, because the decision carries an `expires_at`
5. Cancel a request when you stop waiting, so reviewers stop seeing it
