[2] It was thought to be the first ever competitive game behind closed doors at Wembley and was Northampton Town's first appearance at the stadium since the 2013 Football League Two play-off final.
Andy Williams scored Northampton Town's fourth goal late in the game to ensure his team won the match 4–0 and secure promotion to League One.
After a goalless first half, Cohen Bramall scored direct from a free kick with nine minutes of the game remaining, and the match ended 1–0 to Colchester United.
Jayden Richardson then gave Exeter an aggregate lead 13 minutes into the second half but an equaliser from Courtney Senior sent the match into extra time.
Charlie Raglan put the visitors ahead midway through the first half before Conor Thomas made it a final score of 2–0 with four minutes of the game remaining.
The BBC reporter Tom Garry described Evans, on loan from Wigan Athletic as putting on an "impressive goalkeeping display", keeping his third consecutive clean sheet.
Twelve minutes into the second half, Callum Morton levelled the aggregate score as the ball deflected off his head after a defensive mix-up in the Cheltenham Town box.
[17] Exeter had also re-gained promotion to the Football League with victory over Cambridge United in the 2008 Conference Premier play-off final at Wembley.
[19] The highest scorer for Exeter City during the regular league season was Ryan Bowman with 13 goals followed by Broom on 8, while Sam Hoskins and Andy Williams were joint-top marksmen for Northampton Town with eight apiece.
[27] The Exeter City manager Matt Taylor made one change to his team from the semi-final against Colchester with Nigel Atangana replacing Archie Collins.
In the fourth minute, Exeter City's Randell Williams was fouled by Scott Wharton who was shown the first yellow card of the game: the resulting free kick was cleared.
He controlled the ball on his thigh, feigned to shoot to send Jake Taylor the wrong way before taking a shot which deflected off Martin's heel past Jonny Maxted in the Exeter City goal.
[29][30] Two minutes later, Northampton Town were forced to make their first substitution of the match: Adams went off with a leg injury to be replaced by Mark Marshall.
On 59 minutes, Exeter City were reduced to ten players when Dean Moxey was sent off after being shown a red card for a late tackle on Watson.
Collins was then brought down in the box as he went to shoot, but no penalty was awarded and replays indicated that Northampton Town's Marshall won the ball legally.
A minute after his introduction, Andy Williams increased Northampton Town's lead further when he scored from close range after Smith headed on a long throw-in from Goode.
[36] The Exeter City manager Taylor admitted that conceding an early goal had a negative impact on his team, noting "we started as men but quickly turned into boys".
