SaFi Bank Space : 🟢 Epic: Attempted Failed Transaction - Error Messages (MVP)

This epic refers to the implementation of the mapping of the error messages produced by Paynamics

All response codes including error codes will be converted to user-friendly & formal messages when reverting back to the user and implemented.

Execution steps

1. the integration service (i.e., payment aggregator/partner/merchants) will respond with an error code/message
   1. If some external services do not have any response code, we will use the response message instead
2. mapping service will compare the response from the integration service with a relational database, where the mappings are stored
3. a more user-friendly (or formal) error message is selected and displayed to the user
