The Aptean AP Invoice Automation connector synchronizes invoice data from AP Invoice Automation (APIA) to Business Central through inbound events processed via Aptean Integration Platform (AIP) connector.

These inbound events allow invoices processed in APIA to be automatically imported into Business Central as purchase invoices.

The connector supports the following inbound invoice types:

Expense invoices
Invoices that contain expense-related charges which are mapped to G/L accounts in Business Central.

Purchase invoices
Invoices that reference purchase orders or receipts and create item-based purchase invoice lines.

Mixed invoices
Invoices that contain both expense lines and purchase lines, allowing the system to process multiple types of charges within a single invoice.
