The goalkeeper was not at the club last season when City lost a dramatic Wembley play-off final 3-2 to Blackpool, leading to a feeling of despair which has returned to all Bluebirds fans this week as Norwich wrapped up second spot.
But Heaton is adamant Cardiff can banish the nightmares of their 3-0 defeat to Middlesbrough on Monday as they look to claim play-off joy this time around.
"We'll be fine," he told the South Wales Echo. "We've got the mindset that if it was automatic, great, but if not we can just go and win the play-offs.
"It's a great mentality to have, we are not all-or-nothing about automatic promotion. It's going to be a good test of character, but there are enough characters in the squad to get through it."
He added: "We'll take anyone in the play-offs, we don't fear anyone so it wouldn't be a problem who it is. I don't think teams will want to play us, especially given our recent form."
