Troubleshooting
Messages in the checkout
What the customer may see in the checkout, what it means and what you do about it.
| Message | Cause | Action |
|---|---|---|
| The checkout did not respond — try again in a moment, with a grey line "Kustom 400 · BAD_VALUE …" | Kustom rejected the order. The grey line shows Kustom's code and text | Read the text: purchase_currency means the currency is not allowed for the country (check markets and enabled currencies), confirmation that the store address is not https |
| Payment in SEK is not enabled for Sweden, with the button "Switch to NOK and continue" | The country + currency pair is not among the Kustom markets | The customer can switch directly. Add the pair under Kustom › Settings if it should work |
| Live rates are unavailable right now — standard prices are shown | Sendify did not answer or rejected the quote | The checkout uses the fallback price. Check the integration's activity log; common causes are missing weight, invalid sender postal code or a sandbox that is down |
| Enter your postal code and we will fetch shipping options | The postal code is not complete | Not an error |
| The item is sold out | Stock ran out between cart and payment | The customer removes the line. Check the stock level |
| The checkout session expired | The customer was inactive for a long time, sessions live for 48 hours | The customer starts over |
| The checkout is not enabled for this shop yet | Kustom is not connected or selected | Connect under Integrations and select under Storefronts › Checkout |
