Feedback on sale

Once a sale (or purchase) is fulfilled, the Seller may leave his/her feedback on the transaction and qualify the counterparty.
When the transaction is qualified as fulfilled, "custom" and "me1" shipments show that the product has been already delivered; therefore, bear in mind that this process should be started only if you are sure that the product has been delivered to the buyer. This way when the seller qualifies, a message will be sent to the buyer asking him/her about the sale and requesting confirmation of such sale product delivery.
Currently, this action is valid only for tracking shipment delivered statuses, that is, it has no impact on the involved Seller's reputation; it should be always applied to change status to delivered in sales without Mercado Envíos, moving these sales to the completed lists.

There is one pair of feedback_id for each transaction: sale and purchase. In this test example,“id”: 5040068160032 is the feedback_id for the sale-side , while “id”: 5040068164512 corresponds to purchase-side.

Notas:

In the case of shipments without Mercado Envíos (or Customized Shipping), it is essential to have the sales feedback for a successful closure. This is the confirmation that the buyer has received their product and is satisfied with the transaction. To validate that sales feedback has been received properly, it is important to verify certain attributes, such as:

"role": "buyer",
"extended_feedback": [],
"date_created": "2020-09-29T18:39:36.000-04:00",
"fulfilled": true,
"rating": "positive",
"visibility_date": "2020-09-29T18:39:35.000-04:00",
"message": "Produto chegou no prazo!",
"has_seller_refunded_money": null,
"site_id": "MLB"

It's important to highlight that once the sales feedback has been received and it has been confirmed that the transaction has been successfully completed, the payment is released to the seller. This is a crucial step to ensure reliability and efficiency in all transactions conducted through Mercado Libre.
