Norwich City's number one was a surprise selection by Roy Hodgson to travel to this summer's European Championship, but he has had an impressive debut season in the Premier League.
In a particularly impressive debut season for the Canaries, Ruddy has made 37 appearances as the club finished in 12th, 11 points clear of relegation.
The 25-year-old has never presented his country, with Wednesday’s announcement being the first time he has received a call-up to the international setup.
"It was quite surreal. I can't wait to get started now. It's fantastic for me to be able to repay the faith Paul Lambert put in me. It caps off a wonderful couple of years I've had at Norwich and we've had a fantastic season too,” he told Sky Sports News.
"There were a couple of times, it got a bit difficult, but with the determination and the desire not to give up, it's paid off now and it's nice to look back and remind myself what could have happened. It's a wonderful opportunity and it caps off a wonderful year for me."
The goalkeeper the pointed to the his club coach, Lambert, as one of the major reasons behind his success.
"You see what he's done with Norwich, not just me individually, but as a club," Ruddy said. "This season in the Premier League has been the biggest achievement we've had at the club - getting to 47 points - it's just his management style, the will to win and confidence he gives us."
Ruddy then commented on his fellow domestic teammates who failed to receive call-ups including Grant Holt, who was overlooked by Roy Hodgson despite an impressive season where he ended up as the Premier League’s second most potent English goalscorer.
"I can't talk about people who should or shouldn't have been selected," he said. "If I'm having an opinion then I think he should have gone - 17 goals count for itself. He's a great guy and a great leader at Norwich. I'm very disappointed for him.
"Same with Wes Hoolahan and Anthony Pilkington who could have got in the Ireland squad, and probably deserve to get a bit more recognition. I think a club like Norwich will take staying in the Premier League for another season and make sure the better players are coming back stronger."
The former Everton keeper also revealed that he had originally planned to get married before hearing the news, and will now miss the scheduled warm-up friendly against Belgium on June 2 before joining up with the squad just before it flies out to the tournament.
"I'm due to get married on June 2, and I've had this conversation with my family and they've said they don't want to cancel it. So all being well, barring any injuries, then finger crossed I'll be getting married, then I'll join up with the squad and then on to Poland."
