What cc_rejected_invalid_installments means in Mercado Pago

Payment status: rejected

Short answer

The payment method does not process payments in the number of installments that was requested.

If you are the buyer

Choose a different number of installments or another payment method.

If you are the seller

If buyers hit this often, check which installment options your checkout offers.

If you are the developer

General engineering advice (not from Mercado Pago's documentation): Make sure the installments you send come from the options available for that payment method and amount, and let the buyer pick again.
