Create Batch Invoice

This API allows merchants to create a batch payment request. This scenario is useful when a set of invoices will be paid in a batch using a single invoice number.

Key business rules

1. All invoices of a batch shall have the same currency.

2. All invoices of a batch shall have the same payment account identifier.

3. An expired invoice cannot be included in a batch.

4. An invoice can only be included in one and only one batch.

5. A paid invoice cannot be included in a batch.

6. The expiration time of a batch invoice is the earliest expiration time of all the linked invoices.

7. Once an invoice is in a batch, it cannot be paid individually anymore.

8. A batch invoice cannot be paid partially.

9. Once a batch invoice is paid, all the linked invoices will be marked as paid in IremboPay, but IremboPay will notify the merchant endpoint only for the batch payment (linked invoices will not be included in the payment notifications).
