The Hammers qualified for Europe through the backdoor thanks to the FIFA Fair Play rankings which was great for the club and fans.
It throws up some interesting and bizarre trips across the continent and depending on how far they progress could add as many as 23 matches to West Ham's season.
Slaven Bilic was again in the stands to watch this one, leaving team duties to Academy manager Terry Westley, who will step aside for the second round of qualifying.
But did we learn much from the game?
1) Sam Allardyce was wrong to ignore starlet Elliot Lee
West Ham fans have been calling for the son of former England and West Ham star Rob to be given his chance in the first team for well over a year.
Excited by his supreme scoring record at youth and U21 level, many supporters used his lack of game time - particularly when the Hammers suffered a string of injuries to their strikers in the last two seasons - as a rod with which to beat former manager Sam Allardyce.
They felt Big Sam had no interest in promoting academy players, something the club prides itself on. Lee was given a couple of late substitute cameos under the now departed manager but was farmed out on loan. He showed against Lusitanos that Allardyce was wrong to ignore him by marking his full debut with a well-taken goal and being named man of the match. Cue comparisons to Hammers legend Tony Cottee.
2) The Europa League is not all glamour
If any proof was needed that playing in Europe is not always what it is cracked up to be, a trip to Andorran minnows Lusitanos provided it. A stadium holding less than 1,000 fans and sporting an artificial pitch was the venue for the game. The club could not live stream the match over the internet, because the signal was not good enough and all the hosts seemed to want to do was start a fight with their visitors from east London.
It is a far cry from the kind of European nights we are used to seeing in television. But the Hammers must first go through the pain to be rewarded with plum ties later on in the competition.
3) Terry Westley is West Ham's best ever manager
If Hammers Academy manager Terry Westley is remembered for nothing else in his career let it be this. He is officially West Ham's best ever manager boasting a 100% win rate.
Ok he may have only taken charge of two games but the pressure was on considering he had new boss Slaven Bilic watching on from the stands and the club's ambitious co-owners David Sullivan and David Gold desperate to make the competition proper.
With four goals scored and none conceded over the two games it is a record that is unlikely to be broken anytime soon.
Players, both senior and youth, remarked how much they enjoyed their time under Westley preparing for the matches.
And the experience will bode him well in terms of knowing the levels the club's emerging talent need to reach to realistically compete for a first team spot.
4) Diafra Sakho needs to keep his cool under provocation
When Diafra Sakho was sent off after 14 minutes, in all honesty, it mattered very little given that his side were already 3-0 to the good against weak opposition.
But the popular striker cannot afford to leave his team in the lurch by reacting to provocation, particularly as they progress to face tougher teams.
He is the club's main goalscoring threat and will now be missing for the next round. Opposing players will see him as a weak link mentally if he reacts to being wound up so easily and he will be a target. We must remember he is still only 24 so he must learn from this and ensure it doesn't happen again when he returns.
5) Perhaps youngster Josh Cullen needs to go out on loan?
With the match all but over before kick-off, much of the excitement in the build-up surrounded the news that West Ham were handing a full debut to exciting Academy prospect Josh Cullen in centre midfield.
The swashbuckling youngster is in the mould of the likes of Joe Cole and has shown some glimpses of real talent in his cameos before this game.
Brave as a lion he is usually very direct and runs at opposition defences. May fans expected to see him involved in the thick of the attacking action but he was on the periphery for the majority of the match.
That was more down to the ever decreasing pace and interest in the dead rubber tie from both sides. But perhaps a loan move to get regular competitive first team action might be best for his progression.
He showed some frustration by getting booked late on before being withdrawn. Did do anything wrong but would definitely benefit from a move to a Championship or League One side looking to add some creativity to their team.
