What cc_rejected_duplicated_payment means in Mercado Pago

Payment status: rejected

Short answer

The buyer already made a payment for that same amount.

If you are the buyer

If you need to pay again, use another card or payment method.

If you are the seller

Look for the earlier payment before asking the buyer to pay again.

If you are the developer

General engineering advice (not from Mercado Pago's documentation): Before showing an error, look up the earlier payment for the same order and check its status. If it was approved, fulfil the order from that payment. Use an idempotency key per order attempt so that a double click does not create a second charge.

The meaning comes from the Mercado Pago developer documentation, verified on 2026-11-04. Buyer and seller steps follow from it; developer notes are general engineering practice, not Mercado Pago documentation.
