signifyd api returned 500 on case fetch: how to fix

Not specified by the original author.

TL;DR

A 500 on a Signifyd case fetch is almost always transient. Retry a few times with backoff and a request id, validate the case id before retrying, and serve your last cached case state while Signifyd recovers. Escalate to a human if failures persist past a few minutes. Log every attempt so support has a clean timeline.

signifyd api returned 500 on case fetch: how to fix

Use this when

• Case lookups fail intermittently with 500.
• One case fails while others succeed.
• The failure starts suddenly with no code change on your side.

Not for this skill when

• You get 400s. That is a request shape problem, and retrying will not help.
• Cases stay open after investigation. That is a workflow issue.

Steps

1. Validate the case id format before retrying: correct length, correct prefix, no whitespace. Verify: a malformed id is fixed, not retried.
2. Retry the fetch up to three times with exponential backoff and a unique request id per attempt. Verify: each attempt logs its own request id.
3. Check the Signifyd status page for an active incident. Verify: you know whether the 500 is yours or theirs.
4. While retries fail, serve your last cached case state and mark it stale. Verify: downstream code sees the stale flag, not silent old data.
5. If 500s persist past a few minutes, alert a human and open a support ticket with request ids and timestamps. Verify: the ticket carries the exact failing window.

Variant phrasings

signifyd case api 500 error

Shortest search form.

signifyd 500 fetching case

Log-line wording.

signifyd api server error case lookup

Support-ticket phrasing.

Compatibility: Signifyd Case API. 500 is a server-side failure; treat 4xx and 5xx differently in your retry logic.

Why it happens

Transient 500s come from Signifyd's side: deploys, hot partitions, or a single case record hitting a bad path. Your code did not break; the service hiccupped. Bounded retries exist for exactly this.

Edge cases / pitfalls

• Never retry 400s with the same backoff loop. A bad request fails forever.
• Cap retries. An unbounded loop turns their incident into your outage.
• Stale cache needs a visible flag. Serving old case state silently is worse than an error page.
• If the same single case 500s while others succeed, note the case id in the ticket. A record-specific 500 is a different bug from a service-wide one.
• Alert on rate, not on single 500s. One is noise; a sustained spike is the incident.

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.

TL;DR

A Signifyd 403 on writes with reads working is a scope problem, not a broken key. Keys are issued with permissions, and a key created for reporting or read only integrations will fetch cases all day and refuse every create or update. Check the key role in Signifyd team and API settings, generate a key with case write access for the integration that needs it, and swap it in that service config only. Then retest the exact write that failed before rotating anything else.

signifyd api 403: api key lacks case write scope

Use this when

• GET case calls succeed and POST or PUT case calls return 403.
• A new integration or a new service cannot create cases while the old one can.
• The key was recently reissued by an admin or security team.

Not for this skill when

• All calls return 401. The key itself is wrong, revoked, or sent incorrectly.
• One specific case returns 403 while others write fine. That can be case state, for example writing to a closed case.

Steps

1. Reproduce the split: run one read and one write with the same key and record both status codes. Verify: reads return success and the write returns 403, confirming scope over validity.
2. Open Signifyd API key settings and read the permissions attached to the key your service uses, identified by its name or last characters. Verify: you can name the exact scopes the key holds.
3. Create or request a key with case write scope for this integration, named for the service that will use it. Verify: the new key exists with the needed scope and a clear owner.
4. Update only the affected service configuration, restart or redeploy it, and retry the original failing write on a test case. Verify: the write succeeds and the case appears in the console.
5. Audit other services for the same under scoped key before they hit writes in production, and record key scopes in your integration inventory. Verify: the inventory lists each key, its scope, and its owner.

Variant phrasings

signifyd 403 on create case

Create focused phrasing.

signifyd key read only cannot update case

Scope phrasing.

signifyd forbidden on case write api

Forbidden phrasing.

Compatibility: Signifyd API keys on current team plans. Scope names follow the Signifyd developer documentation; key management requires an admin role in the console.

Why it happens

Least privilege key hygiene, done without a scope inventory, produces keys that are valid but too narrow for the job they were handed to. Because reads work in testing, the integration passes smoke tests and fails on its first real write, usually during a live fraud case when the timing hurts most.

Edge cases / pitfalls

• Do not solve scope problems by sharing the one full access key everywhere. Issue per service keys so a leak or rotation stays contained.
• Closed or guarantee decided cases reject some writes by design. Test writes on an open test case.
• Note the environment: a sandbox key with perfect scope still 403s or 404s against production cases.
