Try out form does not work when POST with application/x-www-form-urlencoded

[fieder]

I have no problems when I specify 'application/json' but the client does not like it when type is changed. I'm submitting a form and this is my swagger definition.

Is it supported?

/tickets/checkout: {
post: {
tags: [
"Tickets"
],
summary: "Checkout",
description: "Initiates payment checkout",
operationId: "jqueryPostCheckoutFormHandlerMercadoPagoUsingPOST",
consumes: [
"application/x-www-form-urlencoded"
],
produces: [
"application/json"
],
