Lightspeed Retail error LSI004 — "Customer not found in Lightspeed"

Created by Emily Campbell, Modified on Thu, 16 Jul at 1:04 PM by Emily Campbell

What this error means

When BRM sends a transaction, it can also send the customer. This error means the customer linked to the reservation doesn't exist in Lightspeed.

Why it happens

The customer was most likely deleted in Lightspeed after being linked, so the ID BRM sends no longer matches anything there.

How to fix it

  1. Open the reservation's customer record.
  2. Re-link it to the correct Lightspeed customer, or clear the stale link so BRM sends the customer fresh.
  3. Retry the transaction.
