Error Message

Service is busy importing another file. 


Worldline declined the transaction because you took many payments in a short period of time, and Worldline could not process them fast enough.

What Worldline is Trying to Tell You

You are sending ACH or EFT payments to Worldline at such a fast rate, that Worldline cannot process the payments quick enough.

Next Steps

  • You can safely retry these payments by attempting another payment
  • If you contact Worldline, they may be able to speed up processing speed for you
  • If this is occurring when ChargeOver is automatically processing subscription payments, enabling ACH or EFT batching may also help. This means that ChargeOver will bundle a large amount of payments into a single batch settlement with Worldline, instead of sending one settlement batch per payment
