How to use Charge EIPP API?

The batch_payment_details field allows for the breakdown of a total order amount into multiple payment entries.

This is useful in cases where an invoice is settled in parts or where multiple transactions correspond to a single order.

Each entry in batch_payment_details represents a separate payment installment associated with unique metadata.

Here’s a dedicated section on Settlements for the documentation:

Settlements

The Settlement process in the Charge API finalizes and records the payments made for an order, allowing merchants to reconcile received funds with their internal records. During settlement, all entries in batch_payment_details—including metadata in extra_fields—are exported and made available to the merchant. This enables efficient and accurate tracking of each payment installment associated with an order.

Key Features of Settlement

• Export of Extra Fields: Every extra_fields entry included in the batch_payment_details section is exported during settlement. This data includes key-value pairs for specific identifiers (e.g., invoice numbers, order references) that the merchant can use for internal reconciliation.

• Reconciliation-Ready: With the export of extra_fields, merchants can easily match incoming funds with individual payment details, enabling a seamless reconciliation process. Unique identifiers like invoiceNumber in extra_fields provide precise tracking for each payment installment.
