Successful payments (batch) - Multiple Successful payments within an objects array :

• Batch payment webhooks are delivered with the objects array (plural), triggered when the bank's ACK file is processed.
• Each webhook carries up to 100 payments; batches larger than 100 are split across multiple webhooks.
• Partial settlements — where only some payments in a batch are confirmed in a given ACK cycle — updates for those payments will be delivered first, with the remainder arriving in subsequent webhooks as later ACK files are processed.
• All payments inside an objects array belong to the same batch, but you should still loop through the array and process each payment independently using its id rather than relying on order or position.
