OTP was entered correctly but rejected
In a small number of cases, a customer insists they entered the correct code but Cartsaver rejected it. The possible reasons are finite and each is quick to test.
1. The code expired
Section titled “1. The code expired”- Default expiry: 10 minutes from send.
- In Cartsaver → Logs, compare “Sent at” against the verification attempt timestamp.
- If the gap exceeds the configured expiry, the code is dead.
Fix: ask the customer to tap “Resend” for a fresh code, or raise the expiry in WhatsApp Order Confirmation settings.
2. Attempt limit exceeded
Section titled “2. Attempt limit exceeded”- Default: 3 attempts.
- After repeated failures, the code is locked even if a later entry is correct.
- Logs show the “Attempts” count.
Fix: raise the limit in WhatsApp Order Confirmation settings, or resend a new code from the order detail screen.
3. Customer typed on a different number
Section titled “3. Customer typed on a different number”- Some customers use multiple WhatsApp numbers. They may read the message on one device but type on another linked to a different number.
- Cartsaver matches the code to the order’s phone number, not the device.
Fix: confirm with the customer that they’re using the same number they entered at checkout.
4. Accidental whitespace
Section titled “4. Accidental whitespace”- A copy from WhatsApp sometimes includes a leading or trailing space, which can register as a different value.
- Cartsaver trims input automatically in recent versions; if a customer reports this after a browser or keyboard update, ask them to type the code manually.
5. Relying on auto-verify
Section titled “5. Relying on auto-verify”- If Auto-verify is enabled but the customer tapped the link in a different browser session (with another account logged in), the automatic verification can silently fail.
- Manual code entry should still work as a fallback.
6. Transient network issue
Section titled “6. Transient network issue”Bad network on the customer’s side can cause a successful submission to look like a failure.
Fix: ask them to retry on a different network, or after a few seconds.
When many customers report it at once
Section titled “When many customers report it at once”If multiple customers report the same issue in a short window:
- Check Cartsaver → Logs for patterns (same country, provider, template).
- Notify support immediately — it may be a Cartsaver-side or provider-side incident.
