Troubleshooting and FAQ

"Dry-run is on: nothing was sent to Velocity". This is expected until you switch on Book real couriers on Logistics → Velocity → Settings.

"Velocity pickup warehouse isn't registered yet". Fill in the whole pickup address on Carrier Accounts and save with dry-run off, or paste an existing Velocity warehouse ID.

No Velocity price at checkout. Check that the shipping method uses carrier Velocity with Realtime (Carrier API) rates, that Show Velocity rates at checkout is on, and that the pincode is serviceable. The method's own price is used when Velocity cannot quote.

Failed deliveries, returns, COD remittance. Not in CartWhizz yet; use the Velocity dashboard.
