onboarding agent timed out polling for webhook delivery confirmation that failed

Fix the onboarding agent failing silently when webhook delivery confirmation never arrives

TL;DR

Track every webhook you wait on in a delivery ledger with a deadline. If the confirmation is not recorded by the deadline, the run fails that step loudly instead of drifting on. Silence is not success; an unconfirmed webhook is an open question the run must answer before moving on.

The problem

step 6: sent provisioning webhook to partner, awaiting confirmation...
confirmation: never arrived (partner endpoint was down)
agent: proceeded to step 7 as if confirmed
result: partner never provisioned, run reported success

Fix it

Step 1: Record every outbound webhook in a delivery ledger

Log the event id, destination, payload hash, and send time before you wait for anything. The ledger is the source of truth for what is outstanding.

Expected: you can list every unconfirmed webhook at any moment.

Step 2: Give each wait a deadline

Set a confirmation timeout per webhook (minutes for sync partners, longer for async ones). When the deadline passes with no confirmation, the step fails - it never silently proceeds.

Expected: a missing confirmation becomes a loud failure within a bounded time.

Step 3: Match confirmations to ledger entries

When a confirmation arrives, match it to the ledger by event id and mark it confirmed. Unmatched confirmations get logged and investigated, not ignored.

Expected: the ledger always reflects reality: sent, confirmed, or failed.

Step 4: Retry with backoff, then escalate

On a missed deadline, retry the webhook with exponential backoff up to a small cap, then fail the step and escalate with the ledger entry attached.

Expected: transient partner outages self-heal; real outages become tickets.

Step 5: Prove the loud failure in staging

Point the webhook at a black-hole endpoint and run the flow.

Expected: the run fails at the webhook step with a clear "confirmation never arrived" error, and nothing downstream executes.

When this applies

• Downstream steps run even though a webhook confirmation never came back
• Runs report success while the partner side never provisioned
• The agent waits on webhooks with no timeout and no tracking

When it doesn't

• The confirmation arrives but carries wrong data (a payload problem)
• The webhook itself fails to send (a sender problem, fix the send path)
• You use polling instead of webhooks (then fix the poll loop's timeout)

Compatibility

Stripe, GitHub, Slack, and Segment webhooks; any partner callback flow where the agent waits on an external confirmation.

Variant phrasings

webhook callback never came and the run continued anyway

Same fix. The run treated "no news" as "good news" because nothing enforced the wait.

onboarding step skipped waiting for partner confirmation

Check whether the wait was even implemented or just implied by the plan order. Implied waits are not waits.

Why it happens

The plan says "send webhook, then continue," and the agent reads that as sequential actions with no verification between them. Waiting was never coded because in the happy path the confirmation arrives instantly. The failure mode - partner down, event dropped, callback lost - leaves no trace in the agent's world, so it marches on and reports success for work that never happened.

Edge cases

• Duplicate confirmations: idempotent ledger updates so a double-ack does not double-provision
• Late confirmations after the step failed: reconcile on arrival instead of dropping them
• Partners that confirm out of band (email, dashboard): the ledger needs a manual-confirm path

If it still fails

• Capture the ledger entries, the retry log, and the partner's receive log before changing anything else.
• Reproduce with a single test webhook so you are not debugging a crowd.
• Check the partner status page; outages look exactly like ledger bugs.

Prevention

• Every outbound webhook the agent waits on gets a ledger entry and a deadline from day one.
• Dashboards show unconfirmed webhooks aging in real time.
• Alert when unconfirmed count spikes; a spike means a partner outage, not bad luck.

Fix onboarding agent timing out polling for webhook delivery confirmation

TL;DR

The agent times out because it polls for a delivery confirmation that will never come, usually after the delivery already failed. Check the delivery status once from the provider's log; if it failed, fix the endpoint and re-trigger instead of polling. Polling a dead delivery is the bug.

The error

Onboarding agent timeout
Timed out polling for webhook delivery confirmation that failed.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=onboarding agent timed out polling for webhook delivery confirmation that failed"

Fix it

Step 1: Check the provider delivery log

Look up the delivery in the provider's dashboard or API.

Expected: You see the real status: delivered, failed, or never sent.

Step 2: Stop polling dead deliveries

If the delivery failed, stop the poll loop immediately.

Expected: The agent stops waiting on something that will never succeed.

Step 3: Fix the endpoint issue

Address whatever the delivery log shows: 4xx, 5xx, or timeout.

Expected: The endpoint is healthy.

Step 4: Re-trigger the webhook

Send a fresh webhook or replay the event from the provider.

Expected: A new delivery attempt starts.

Step 5: Poll the new delivery with a deadline

Poll the fresh delivery with a bounded timeout and backoff.

Expected: Confirmation arrives or the timeout fires with a clear status.

When this applies

• Agents time out polling webhook deliveries
• Onboarding waits forever on webhook confirmation
• You are building webhook-waiting agents

When it doesn't

• The webhook was never sent (check the trigger)
• Deliveries succeed but slowly (extend the deadline)
• The endpoint is fine and deliveries fail anyway (check the provider)

Compatibility

Webhook delivery logs: Stripe, GitHub, Segment, and others.

Variant phrasings

agent polling webhook timeout

Same failure. Check the log first, poll second.

webhook delivery confirmation never arrives

Never arrives usually means failed, not slow. The log tells you which.

onboarding stuck waiting webhook

Stuck waits need a deadline and a fallback path, not infinite patience.

Why it happens

Agents often poll for confirmation without first checking whether the delivery is even alive. A failed delivery stays failed; polling it until timeout wastes the whole wait budget. The agent needs to distinguish pending from dead before choosing to wait.

Edge cases

• Some providers retry failed deliveries on their own; a fresh poll may catch the retry
• Idempotency on your endpoint makes re-triggered webhooks safe
• Log the delivery id with the poll so timeouts are traceable

If it still fails

• Reproduce with a minimal run: one user, one file, one step.
• Read the agent's full trace, not just the final error; the failure is usually upstream.
• Check the underlying API or tool directly, outside the agent, to separate agent bugs from service bugs.
• Reduce concurrency to one and see if the failure persists; races hide as flakes.
• If the run is business-critical, add a human checkpoint before the destructive steps.

Prevention

• Checkpoint long runs so any failure resumes instead of restarting.
• Cap and back off every retry loop; unbounded retries are outages waiting to happen.
• Validate inputs at each pipeline stage; fail fast with clear errors.
• Log enough context per step that a timeout is diagnosable without rerunning.
• Give destructive steps a human checkpoint or a dry-run mode.

TL;DR

MDM push confirmation is asynchronous and slow; blocking on it with a fixed timeout fails. Poll with backoff up to a deadline, accept a webhook callback as the success signal, and hand off to a human queue on deadline expiry.

The query

provisioning agent timed out waiting for jamf mdm push confirmation

Use this when

• provisioning times out waiting for Jamf push
• devices enroll minutes after the agent gave up
• the agent marks devices failed that later succeed

Not for

• Jamf push certificate expirations
• devices that never check in at all
• enrollment invitation problems

Steps

1. Replace the fixed sleep with polling that backs off, checking the Jamf device record. Expected output: the agent observes check-ins without blocking.
2. Set an explicit deadline, such as 30 minutes, after which the agent stops waiting. Expected output: the wait always terminates.
3. Prefer a Jamf webhook on enrollment complete as the success signal over polling. Expected output: confirmation arrives as an event.
4. On deadline expiry, file a follow-up task with the device serial instead of failing the provisioning. Expected output: a human or later run picks it up.
5. Record the actual time-to-enroll to tune the deadline. Expected output: the deadline matches reality.

Applies to

Jamf Pro webhooks and API, provisioning agents, Apple device enrollment.

Variant phrasings

Push confirmations arrive but late

Lengthen the deadline; the design already handles it gracefully.

Webhook never fires

Fall back to polling and alert that the webhook subscription needs repair.

Why it happens

APNs delivery and device check-in timing are outside your control. Synchronous waits encode a guess about that timing, and every guess is eventually wrong.

Edge cases

• Idempotency matters: a late confirmation after handoff must not double-provision.
• Log the serial at every stage; without it, late events cannot be matched.
• Weekend enrollments are slower; consider calendar-aware deadlines.
