What cc_rejected_3ds_mandatory means in Mercado Pago

Payment status: rejected

Short answer

The payment was rejected because it did not go through the 3DS challenge, which was mandatory.

If you are the buyer

Try again and complete the 3DS authentication step if your bank asks for it.

If you are the seller

Ask the buyer to retry.

If you are the developer

General engineering advice (not from Mercado Pago's documentation): Check that your integration implements 3DS and takes the buyer through the challenge before you create the payment.
