fraud agent stalled waiting for signifyd sla callback that never came

Not specified by the original author.

TL;DR

An agent that waits only for a Signifyd callback has no defense against the one callback that never comes, and its case, and the customer order, wait forever. Build the wait as a bounded state: record when the case was submitted and the expected decision window, poll Signifyd for the case outcome on an interval after that window, and at the hard limit escalate to a human with the case id, submission time, and poll history attached. Most cases resolve by poll, because the outcome usually exists in Signifyd and only the notification was lost.

fraud agent stalled waiting for signifyd sla callback that never came

Use this when

• Agent cases sit in a waiting on Signifyd state far beyond normal decision times.
• Signifyd console shows a decision the agent never acted on.
• Orders are late because an agent run never resumed.

Not for this skill when

• The case is inside Signifyd normal investigation window. Polling early adds noise, not speed.
• Signifyd shows the case still open with no decision. Escalate the case with Signifyd, not just the agent wait.

Steps

1. Add wait metadata to every submitted case: submitted time, expected window, and poll schedule, stored on the case rather than in agent memory. Verify: a waiting case shows its age and next poll time in the queue.
2. Implement polling after the expected window: fetch the case from Signifyd and act on any final guarantee or review outcome found. Verify: a staged case with a suppressed callback completes by poll.
3. Set a hard wait limit, for example twice the normal SLA, at which the agent stops waiting and escalates with full context instead of polling forever. Verify: a staged never resolving case escalates at the limit with its history attached.
4. Reconcile daily: list every agent case waiting past the window and compare with Signifyd outcomes, clearing any stragglers the poller missed. Verify: the daily report shows zero unexplained aged waits.
5. Track callback arrival rate as a health metric so a rising miss rate triggers webhook investigation before cases pile up. Verify: the metric exists and an artificial dip alerts the team.

Variant phrasings

agent waiting signifyd decision never came

Missing decision phrasing.

signifyd callback lost agent stuck

Lost callback phrasing.

poll signifyd case outcome agent timeout

Polling solution phrasing.

Compatibility: Signifyd case API and webhooks with any agent orchestration framework that supports scheduled wakeups or durable timers. Poll intervals should respect Signifyd API rate limits.

Why it happens

Callback only designs assume webhook delivery is guaranteed, and it is not: endpoints fail, signatures break, queues drop events. Human teams notice a stale case because a customer complains; an agent in a wait state has no impatience, so the failure mode is silent and indefinite unless the wait itself is engineered with a deadline and a second path to the answer.

Edge cases / pitfalls

• Polling too aggressively burns API quota and can slow the very system you are waiting on. Poll on a widening interval.
• A case decided while the agent was stalled may have a stale order behind it, cancelled or already shipped. Revalidate the order before acting on a late decision.
• Keep the escalation human readable: case id, order id, wait duration, and last known Signifyd status, not a raw agent trace.

TL;DR

A 40-second lookup should never block the agent. Fire the lookup asynchronously, poll with a short timeout, serve repeat lookups from a local case cache, and escalate cases that stay stale past your SLA.

fraud agent timed out on signifyd case lookup with 40s latency

Use this when

• Case fetches take tens of seconds and stall the run.
• The queue backs up behind one slow case.
• The same case gets looked up more than once per run.

Not for this skill when

• Guarantee decisions are wrong. That is decision logic.
• The API returns errors. That is a failure, not latency.
• Lookups are fast but the agent is slow. That is an agent problem.

Steps

1. Make the case lookup async: fire the request and poll for completion instead of blocking. Verify: the agent keeps working while the lookup runs.
2. Set a short per-poll timeout with bounded retries. Verify: one slow poll does not stall the loop.
3. Cache case results locally with a TTL for the run. Verify: the same case is never fetched twice.
4. Define a staleness SLA: cases unfetched after N minutes escalate to manual review. Verify: no case waits forever in the queue.
5. Track lookup latency per endpoint. Verify: you can show whether 40s is normal or a regression.

Variant phrasings

signifyd case lookup slow agent

Same problem, common phrasing.

signifyd 40 second latency

Symptom-level search.

case fetch timeout signifyd agent

Operational wording.

Compatibility: Signifyd Cases API consumed by an agent review loop.

Why it happens

Case lookups join data across Signifyd's investigation history, so they are slower than score calls, and agents that block on them serialize the whole queue behind one slow case. Async polling plus caching turns the slowest call in the loop into background work the agent does not wait on. Slow lookups also poison agent planning: the agent cannot decide the next step until the case arrives, so async polling lets it do other work, like pulling related transactions, while the case loads.

Edge cases / pitfalls

• Cached cases go stale. Keep the TTL short and refresh cases near decision time.
• Polling too aggressively becomes its own rate limit problem. Use sensible intervals.
• A case that never returns is a signal. Escalate it rather than dropping it.
• Do not let async lookups pile up unbounded. Cap in-flight polls.
• If one case type is always slow, prefetch it at queue intake instead of at decision time.

TL;DR

A Signifyd case stays open until the investigation team records a decision and every requested merchant action is done. Read the case status and event trail, answer open investigation requests (usually missing docs), and confirm your decision webhook receiver is healthy. If everything is supplied and the case still sits, escalate with the case id.

signifyd case never closes after investigation: how to fix

Use this when

• A case idles in review with no status movement for days.
• The investigation phase looks finished but no decision is recorded.
• Your dashboard shows open cases far older than your usual cycle.

Not for this skill when

• The case closed but you disagree with the guarantee outcome. That is an appeal, a different process.
• Case fetch calls return 500. That is an API reliability issue.

Steps

1. Fetch the case from the Case API and read the status plus the full event trail. Verify: you can see every state change with timestamps.
2. Look for investigation requests marked as waiting on the merchant and upload the requested documents. Verify: no request is still flagged as awaiting merchant action.
3. Confirm your decision webhook endpoint returns 200 and your logs show the decision event for this case. Verify: the endpoint logged a delivery attempt for the case id.
4. Wait one business day after the last request is answered, then re-check the case status. Verify: the status moved or a new event appeared.
5. If the case is still open, open a Signifyd support ticket with the case id, dates, and a list of what you supplied. Verify: you get a ticket number back.

Variant phrasings

signifyd case stuck in review

Common shorthand for the same state.

signifyd investigation done but case open

Search phrasing when the team feels finished.

signifyd case status not updating

Symptom-level search from a dashboard watcher.

Compatibility: Signifyd Case API. Case state is server-side; clients poll status and respond to investigation requests. Decision delivery depends on your registered webhook endpoint.

Why it happens

Cases do not close on a timer. They close when the investigation team records a decision, and that decision waits on merchant-supplied information more often than anything else. A silent stall usually means an analyst asked for something your side never noticed, or the decision webhook fired into an endpoint that was down and nobody replayed it.

Edge cases / pitfalls

• Uploaded documents still need analyst review. Uploading is not closing.
• Do not open a second case for the same order. It splits the trail and slows everything.
• Business days only. A Friday upload reads as Monday morning.
• Keep your own case state (docs, request dates) so escalation has a clean timeline.
