I'm working on my own webshop and want it to synchronise well with my Bricklink
store. My software seems to work pretty well, but now I'm wondering, does
it happen that names/numbers of parts change on Bricklink, and if so, how often
does that occur? I want to gauge how necessary it is to do some extra coding
to accommodate for this.

I imagine most parts now have the correct numbers but minifigure can change,
like the extra 0 in SW figs.

Yes, I noticed some added 0's in the pattern numbers of some parts, because
the Bricklink number did not match with what Rebrickable thought was the Bricklink
number. I wonder how regularly such things happen. If it's a rare thing then
I should be fine just whiping and reuploading my entire webshop once in a while,
but if it's regular I should think of some way to update these items specifically.

Those can change as bb... are replacment bricklink numbers when part number is
not known. So wneh somebody discover correct number they can be changed

Thanks Marek, that's useful! Looks quite intimidating anyway, all those changes.
I've now put a module into place that recognises "new" parts that have new
part numbers but are linked to previously existing LotIDs in my inventory. It
then adds the new part and updates the lot with the old part number to zero quantity.
I think that should do the trick

I'm eager to hear more about your webshop. As far as I've understood
you've been dreaming about it for quite some time now, and finally your on
the way. Do you have something to show? Screenshot? Do you have a markedplan?
How do you decide which features to add? How big development team have you managed
to put together?

Good luck

Thanks! You're right! Someone I know put me on the right track with a content
management system that's featured in my hosting package. I'm essentially
able to do it all by myself, thanks to the versatile system, a bit of programming
skills I do have, and €20 I spent on a programmer to tweak some things It
has been a huge amount of work so far, 1. tweaking the store, 2. writing software
that turns inventory files that I download from Bricklink into the format I need,
3. writing an entire database of all parts and 4. finding rights free pictures
of everything. I really don't want to take anything from Bricklink that was
given by contributers and isn't mine, so I'm really working like crazy
these weeks

I won't go sharing much of it, as I don't want to border on inviting
to buy outside of Bricklink. But anyway my main idea is to make a very white,
minimal site with good overview, and make it all Dutch. I'm going to try
to focus on the Dutch market, since I believe there's an untapped market
there for people who aren't insiders but would buy from a friendly accessable
webstore they can understand easily, and use the payment method they're comfortable
with that isn't featured on Bricklink. Also, having my own store means I
can go and advertise it everywhere. That's alot better than constantly having
to tell people that my store is on some platform called Bricklink.

I don't know if I'm right. I could be wrong, but if so, it'll just
mean one wasted summer If I am right, I could be having some great business
and stability for many years to come. But probably I will be having to boost
my inventory alot more in order for my store to be significant enough by itself.
I hope hierachical category system and independent filters for many part properties
are going to be selling points.

I was willing to gamble some €2000 on having someone build me a store, so if
everything fails, I'm fine with just having wasted a lot of time and still
have all my money - except from the €20

The programmer only asked for €13 for the tasks I gave him but I added a tip,
considering that programmers are usually too expensive and too busy

Possibly you should be made aware that Bricklink considers its part names and
numbers to be its own proprietary information, and that using them on your own
commerce site might draw unneeded problems. They have taken action at least once
in the past to require another site to stop using the Bricklink part numbers.

As a result, other sites choose to come up with their own part numbering system,
or they use the LDraw names and numbers, which can be used freely with the proper
attribution.

Of course many BL numbers are the numbers actually molded on the parts by LEGO,
and these are probably safe to use. Also, many BL part names and numbers are
from LDraw. These should also be safe to use.

Thanks for the advice. Actually I'm not "using" Bricklink part numbers -
my sync system just needs to know what is what, so for that part, it's essential
that my software is able to "speak Bricklinkish" - I imagine that's the same
for BrickOwl and for Brickstock. I don't use it in the shop itself for the
customers. Names/descriptions I'm not using at all, I've described them
in Dutch (which was the most exhausting part of the job )
