Added: Support for Cross-Border Transactions

We have added support for cross-border transactions by enabling the creation of non-Nigerian (non-NG) parties.

Behavior Changes

Party Validation Logic

• If a TIN is provided and no address is supplied, the party is assumed to be Nigerian.
  • The TIN will be validated as a Nigerian TIN.
  • If validation succeeds, a default Nigerian address will be applied.
• For cross-border transactions, the address is required.
  • The country is derived from the address object.
  • TIN validation is determined based on the country specified in the address.
  • Non-Nigerian parties are supported when a non-NG country is provided.

Invoice Processing

• Cross-border invoices are not added to the invoice transmission queue.

Backward Compatibility

• This update is non-breaking.
• Existing integrations that omit the address for Nigerian parties will continue to function as before.
