And the two teams are level at the break. The Baggies went in front thanks to Isaac Price's 19th minute free kick - his low shot from 20 yards whistled past Ewen Jaouen at the Gallowgate End to stun St. James' Park - but Bazoumana Touré equalised on his debut.
Joe Willock came close for the Mapgies in the seventh minute. The midfielder - who scored against Liverpool on Sunday - nearly made it two in two games as he made space for a shot but fired wide.
Then Lewis Hall's half-volley was fielded by Matt Ingram, the visiting goalkeeper.
But at the other end, Jaouen - like Touré, making his Magpies bow - was unable to keep out Price's audacious free kick.
New signing Nico González was announced and unveiled to the capacity crowd just before kick-off, creating a raucous atmosphere, but the home fans were silenced when the Championship side went ahead.
Jimmy-Jay Morgan then dragged an effort wide for Albion just before the half-hour mark, but United pushed for a leveller before the interval.
Touré had an opportunity to do just that, but his shot lacked the power to trouble Ingram.
But the Ivorian did equalise in the 38th minute, converting from close range following a searching centre from Dedić.
