The Maltese side beat their Armenian hosts 3-1, ensuring a preferable trip to Malta for Hammers fans.
Shortest break, fastest starters?
The early qualifying rounds of the competition were always going to throw up some unknown opponents and interesting trips across the continent.
The lowdown on Birkirkara
But what do we know about Birkirkara?
First things first, more supporters will be able to travel over for the game as the club's Infetti Ground holds 2,500 fans - double that of FC Lusitanos.
Some might be thinking twice about making the trip, though, because 'Infetti' means 'infected' in Italian and is so named because the fields on which the stadium is built served as a graveyard for victims that had died from the plague in the past.
A pint will cost around €3 for domestic and imported beer. Anyone that does make the trip will need to bring their suntan lotion. Temperatures over there at the moment are averaging at a scorching 32°C.
It is the most populated town on the island, with 22,247 inhabitants.
On the pitch, Birkirkara have won the Maltese Premier League four times. They finished third last season and play in yellow and red, a similar kit to that of newly-promoted Premier League side Watford.
Like against Lusitanos, West Ham will be red hot favourites to qualify for the third qualifying round over two legs, the dates of which are yet to be confirmed.
