Errors
Every API returns the same envelope on failure, so one handler covers the whole catalogue.

UNAUTHORIZEDThe API key is missing, wrong, or for the other environment.
NOT_FOUNDNo resource with that ID or reference exists.
DUPLICATE_REFERENCEThis clientReference was already used. Safe to treat as a repeat of the first call.
RATE_LIMITEDToo many requests. Back off and retry after the Retry-After header.
UPSTREAM_UNAVAILABLEThe biller, bank or network is down. Retry later; nothing was charged.
