Errors

ORDER_TOTAL_DIFFERENT

ORDER_TOTAL_DIFFERENT

The order total submitted at placement does not match the total computed by the server. This guards against stale price data on the client.

Summary

Field	Value
HTTP status	400
errorCategory	validation
retryable	false

When This Fires

• POST /v1/marketplace/orders/place — the amounts.total (or any subordinate amount) on the request differs from the total computed by re-pricing the cart against the live catalog.

The most common cause is a price change between the validate call and the place call (the user's session held a stale catalog), or a client-side rounding mismatch.

Recommended Action

Re-fetch the canonical totals and confirm with the user before retrying:

1. Re-call POST /v1/marketplace/orders/validate to retrieve the fresh amounts block.
2. Diff against what the user previously saw and surface any change ("the price of one of your items has changed").
3. On user confirmation, resubmit place with the updated amounts.

Do not blindly retry with a server-supplied total — the user must accept the new amount.
