Preserve the error message
Store the provider error code, explanation, request time and related order number in a format the operations team can understand. A generic “operation failed” message is not enough to resolve the issue.
Retry in a controlled manner
Temporary connection errors can be retried automatically, but every action must use a unique key to prevent duplicate invoices or shipments. Permanent validation errors should be routed to a person.
Build a single exception queue
Sorting issues from different providers in one screen by priority, waiting time and owner makes daily operations significantly easier.
Implementation note
Adapt these principles to the API, contract and operational conditions of your sales channels. Verify critical workflows with controlled test orders before going live.
