paystack verify endpoint invalid reference: truncated reference from the webhook

Not specified by the original author.

TL;DR

Some webhook payloads carry a shortened form of the payment reference, and Paystack's verify endpoint needs the full reference: the truncated value is rejected as invalid. Recover the full reference from the charge or transaction response stored at payment time, or list transactions to match it, then verify with the complete value. Going forward, persist the full reference from the API response, not the webhook copy.

paystack verify endpoint invalid reference: truncated reference from the webhook

Use this when

• Paystack verify rejects a reference taken from a webhook
• The reference looks shorter than the ones from the API
• Verification works with the API reference but not the webhook reference

Not for this skill when

• The full reference is also rejected (the transaction may not exist)
• The transaction verifies but shows failed
• You are debugging webhook delivery rather than verification

Steps

1. Compare the webhook's reference with the reference returned by the charge or transaction API at payment time. Expected: You confirm the webhook value is truncated.

2. Recover the full reference from your stored API response or by listing transactions around the payment time. Expected: You have the complete reference.

3. Call the verify endpoint with the full reference. Expected: Verification succeeds.

4. Update your webhook handler to look up the stored full reference by the webhook's metadata instead of trusting the webhook's reference field. Expected: Future webhooks verify on the first try.

5. Add a length or format check that flags truncated references before they reach the verify call. Expected: Truncation is caught early with a clear log.

Tool compatibility

Paystack transaction verify and list endpoints; webhook event payloads.

Variant phrasings

paystack invalid reference from webhook

The same failure without the truncation detail.

paystack webhook reference truncated

Names the cause directly.

paystack verify reference not found

How the error reads when the truncated value misses.

Why it happens

Paystack's verify endpoint performs an exact lookup on the full payment reference, while webhook payloads are optimized for notification and can carry shortened or display-formatted values. When your handler feeds the webhook's copy into verify, the exact-match lookup fails. The API response at charge time is the source of truth for the full reference, which is why persisting it at creation time is the durable fix.

Edge cases / pitfalls

• Do not repair a truncated reference by guessing the missing characters; always recover it from the API.
• If you process webhooks before the charge response is stored, buffer the webhook until the reference is persisted.
• Reference formats can change: validate shape, not just length.

TL;DR

Flutterwave's verify endpoint expects Flutterwave's own transaction id, not your merchant txref: passing your own reference returns no transaction was found. Capture the transaction id from the charge response or the webhook payload, then call verify with that id. If you only stored your txref, list transactions filtered by tx_ref first to recover the Flutterwave id.

flutterwave "no transaction was found" on verify: wrong transaction reference

Use this when

• Flutterwave verify returns no transaction was found
• You are verifying with the reference you generated
• Webhook and verify use different identifiers in your code

Not for this skill when

• The transaction is found but shows failed (that is a payment failure)
• You are waiting on settlement or a bank transfer
• The error comes from the charge endpoint rather than verify

Steps

1. Check which value you sent to the verify endpoint: your tx_ref or Flutterwave's transaction id. Expected: You identify the wrong identifier.

2. Pull the charge response or webhook payload for the payment and read Flutterwave's transaction id. Expected: You have the id the verify endpoint expects.

3. Call the verify endpoint with the Flutterwave transaction id. Expected: The transaction is found and its status is returned.

4. If you only have your txref, use the transaction list endpoint filtered by txref to recover the Flutterwave id. Expected: You map your reference to the provider id.

5. Store both identifiers on every payment going forward. Expected: Future verifications use the right id the first time.

Tool compatibility

Flutterwave v3 transaction verify and list endpoints; identifier rules are version-stable.

Variant phrasings

flutterwave verify transaction not found

Short form of the same verify-path error.

flutterwave tx_ref vs transaction id

The identifier confusion at the heart of this error.

flutterwave verify with wrong reference

The mistake described directly.

Why it happens

Flutterwave lets merchants supply their own txref for correlation, but its ledger is keyed by the transaction id it generates. The verify endpoint looks up that internal id, so a merchant txref never matches and the API reports no transaction was found. The two identifiers serve different purposes: tx_ref is your label, the transaction id is the ledger key. Storing both at charge time removes the ambiguity.

Edge cases / pitfalls

• Test and live transactions live in separate spaces: a test tx_ref will not verify against the live endpoint.
• Webhooks carry both identifiers: prefer the webhook's transaction id for verification.
• Do not mark an order paid based on tx_ref alone; always verify with the provider id.

Fix Stripe webhook signature verification failing

TL;DR

Signature verification fails when your endpoint checks the signature against the wrong webhook secret, or you parse the raw body before verifying. Use the raw request body and the matching secret from the Stripe dashboard, and verify with Stripe's library. Never verify against a parsed JSON body.

The error

Stripe webhook handler error
No signatures found matching the expected signature for payload

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=webhook signature verification failed stripe"

Fix it

Step 1: Get the raw body to your verifier

Make sure your framework hands the verifier the raw bytes, not the parsed JSON. In Express that means express.raw for the webhook route.

Expected: The verifier receives bytes identical to what Stripe sent.

Step 2: Confirm the webhook secret matches the endpoint

Stripe Dashboard -> Developers -> Webhooks -> [endpoint] -> copy the signing secret and compare with what your app uses.

Expected: The values match. Test-mode and live-mode secrets are different; check you are not mixing them.

Step 3: Verify with the official library

Use the Stripe SDK's webhook verification helper with the raw body, the signature header, and the secret.

Expected: Verification passes for a real Stripe event.

Step 4: Replay a test event

From the dashboard, send a test webhook to the endpoint.

Expected: Your handler returns 200 and processes the event.

Step 5: Log verification failures with the event id

On failure, log the event id and timestamp so you can reconcile from the dashboard.

Expected: Missed events are visible and replayable from Stripe.

When this applies

• Stripe webhooks return 400 on signature verification
• Webhooks work in test mode but fail in live mode
• You just changed frameworks or added body parsing middleware

When it doesn't

• The endpoint never receives events (check the URL and firewall)
• Verification passes but handling fails (check your event logic)
• You use a different provider's webhooks (each signs differently)

Compatibility

Stripe API webhooks. Official Stripe SDKs (Node, Python, Ruby, and others).

Variant phrasings

stripe no signatures found matching expected signature

The classic message. It means the secret or the body bytes are wrong, not that Stripe is broken.

stripe webhook 400 invalid signature

Same check. Frameworks that parse JSON before the route runs are the top cause.

stripe webhook secret mismatch live mode

Test and live secrets differ. Using the test secret against live events fails every time.

Why it happens

Stripe signs the exact raw bytes it sends. Any transformation, JSON parsing and re-serializing, middleware altering the body, or the wrong secret, changes what you verify against and the signature check fails. The check is doing its job; your inputs to it are wrong.

Edge cases

• Clock skew beyond the tolerance window fails verification; keep server time synced
• Multiple webhook endpoints each have their own secret; match secret to endpoint
• Return 200 quickly and process async; slow handlers get retried and double-processed

If it still fails

• Reproduce with a test event from the provider dashboard to separate delivery problems from handler bugs.
• Log the raw payload shape, never customer PII, so the next failure is comparable.
• Check the provider status page; delivery outages mimic endpoint bugs.
• Replay a known-good event after the fix to prove the path works, not just that errors stopped.
• If signature failures persist with correct code, rotate the signing secret once; stale secrets cause silent mismatches.

Prevention

• Return 200 fast and process async on every new webhook receiver.
• Make event handling idempotent from day one; retries are guaranteed.
• Monitor delivery success rates, not just endpoint uptime.
• Keep signing secrets per endpoint and rotate them on a schedule.
• Reconcile critical events against the provider API, not just webhooks.
