I need transaction_id to be generated only as a numeric and not an alphanumeric.
This is because the customer can use it as a variable symbol when making an offline payment. The bank only requires a number. It would also be better for exchanging information in the payment gateway plugin we are preparing.
I would like to put this as a requirement for choice in the next PMF issue. Now I would need to indicate in which file this is solved and what to change there.
Thank you very much for your help
