Substitute Adam Idah scored a late winner as Norwich started life back in the Championship with a battling 1-0 away win at Huddersfield.
The promising Republic of Ireland international striker had only been on the pitch five minutes, but was never going to miss from close range in the 81st minute after an awful mistake from defender Richard Stearman.
Centre-back Stearman was careless with a poor back-pass and Teemu Pukki crossed for Idah to lash home from inside the six-yard box.
It was tough on the Terriers, who had been good value for at least a point on the opening weekend of the new season.
Town boss Carlos Corberan handed debuts to new signing Pipa and academy graduate Ben Jackson, but last season's leading scorer Karlan Grant was left out of the squad following speculation of a transfer to West Brom.
Winger Adama Diakhaby had a chance for the hosts in the opening minute, but the Frenchman rifled over from 25 yards.
Stearman then went close to giving the Terriers the lead, but his poked shot from Alex Pritchard's corner was cleared off the line.
The Canaries had a really good shout for a penalty turned down by referee Geoff Eltringham not long after.
Xavier Quintilla's pacey delivery looked to strike Juninho Bacuna on the arm, but Eltringham, waved away the visitors' protests.
The Canaries had found some momentum and 10 minutes before the break Kenny McLean let rip with a stinging drive, but his goalbound effort was blocked inside the box.
Former Norwich midfielder Alex Pritchard had a decent opportunity with a free-kick right on the edge of the area, but he frustratingly blazed over.
Josh Koroma went agonisingly close to breaking the deadlock five minutes after the restart, but his powerful right-foot strike flew inches wide of the left upright.
Skipper Christoph Zimmermann headed just over from Quintilla's inswinging corner, while Pukki tried his luck from an acute angle. However, his shot flew well wide of the target as the Canaries continued to search for a breakthrough.
Koroma had a left-foot strike charged down on the edge of the area, but then Farke's team took a fortunate lead after Stearman's attempted pass to Hamer.
Pukki pounced to intercept the ball and his perfect cross saw Idah rifle into the roof of the net to secure maximum points.
