If an API client passes an invalid value for the `TransactionType` parameter, then AlphaCommerceHub responds with a generic message `1003` / «Request failed, technical error» instead of a more meaningful message like «Invalid TransactionType»

It would better to respond with something like «Invalid TransactionType», similar to 1048 / «Invalid OrderID» and 1049 «Invalid PaymentID» responses.

Please pass the payload you used. I just did a test with an invalid transaction type OneStepPaymentx and received 1092 Invalid Transaction Type response
