Summary
Core Theme
This content explains a legal method for scraping Facebook Marketplace data using only a web browser by inspecting network traffic, without violating terms of service. It details how to access and extract raw listing information, including details like price, location, seller information, and media URLs.
if you need to scrape Facebook
Marketplace data I'll show you how to
legally do so using only your web
browser as you scroll through Facebook
Marketplace listings without violating
the Facebook terms of service to get
started at the Facebook Marketplace and
you don't even need to be logged in
unless you want to and browse any
category or location you want you can
put in any of these filters use the
website normally because we're just
going to be recording your web traffic
we don't have to do any automated
interaction that typically fails once
you see the list things you want right
click and hit inspect this opens up
developer tools which will automatically
begin recording your web traffic you'll
see here now that we're recording
refresh this page so Facebook reloads
the first set of results into our
browser and you can just close these
annoying popups they're really desperate
to get you to log in or give them your
location now under the network Tab and
developer tools if you type in graphql
under the filter you can see these API
responses showing us the raw data for
Facebook Marketplace they use to power
the front end it's extremely deeply
nested so you have to keep drilling
through here until you find the listings
and you'll finally see something here
like 1963 Chevrolet and you can see the
number of miles it has here delivery
types most of these cars are going to be
in person but sometimes they do shipping
this ID is useful if you want to look up
the listing on Facebook Marketplace for
even more details you get pricing here
in a bunch of different formats for some
reason and if there's a video attached
to the listing you can get the URL to
see that video here's some more
information about the location of each
listing I can see the city and State
this here is information about the
seller showing them their full name but
I don't want to show that on camera and
if they have photos we can see the
primary photo here and again it's an
image URL and if we search in the
results we can see the HTML version
presented up here with all the data I
just showed you in Json button
userfriendly format now to get the rest
of the listings we simply scroll through
the results and the Facebook API will
send more data to our browser that we're
recording we're not violating the
Facebook terms of service because we're
just browsing the site normally if
anybody asks so I got through about
1,500 results and it looks like I could
keep going but I think that's enough for
this demo to get this data out go into
the network Tab and click this down
arror here called export hor that will
save a hor file containing the raw Json
data to your computer to get the data
out of the hor file check the link in
the description for my no code Facebook
API scraper featuring the hor file web
scraper this will work with any hor file
not just from Facebook Marketplace just
drag and drop it into your browser and
it will securely combine together
similar API requests so you can download
all of the data in one place look for
this group here ending in graphql and
check these fields it should have things
like listing and listing price there may
be a few groups ending in graphql you'll
also see a bunch of images for the cars
these were captured in the hor file
they're not being dynamically loaded so
don't worry about that then down here
you can see the 65 individual API
requests and responses containing all
the data now using these Blue Links here
you can download that raw Json data I
showed you in your browser to your
downloads folder so you can get all this
data in one folder on your computer to
process it yourself but if you just want
a CSV file of all this combined data
scroll all the way up and click this
parse group button here and if you have
a premium account with us you can
download up to 10 rows of this data per
day for free here I'm able to download
all 1500 results we browse through on
Facebook Marketplace and if I want to
see them on Facebook Marketplace I copy
this listing ID and you want to paste it
into this URL format here facebook.com/
Marketplace item listing ID and then
paste in the listing ID here now you can
open this URL up in your browser and see
the official listing Facebook
Marketplace this is this video that I
showed earlier and we can also see that
first image is the primary image we saw
in that Json data other notable Fields
will'll get back are the title of the
listing there is custom title too which
is usually the same in most cases a link
to the primary photo for the listing so
you can loaded in your browser here
here's the price again in decimal format
location City and location state if the
listing has a video you can see that URL
here to the video file if you do access
this media for whatever reason please do
not republish it without consent that's
typically copyright violation but you're
probably fine if you just use this
information for private research you
also see the seller's Facebook
identifier and their name which could be
helpful for example if you're trying to
crack down on people selling illegal
things here's the number of miles which
is obviously only going to be shown on
cars So based on what you browse these
fields will be different and we can see
the shipping or pickup on site it's
mostly going to be in person and there
are a few more Fields here you may find
helpful for example if a listing has
more than one video you can download
that here as a separate collection and
each row will come with a reference to
its parent listing in the download file
and then these here are custom
attributes so this is showing mileage
for cars but if you're scraping phones
for example it may show you storage
capacity or other attributes based on
the products you're browsing so hope you
guys found this useful let me know in
the comments your feedback or what
you're using this data for or if there
are other websites I can help show you
how to scrape and check out this next
