Hack 87 Automatically Keep Track of Auctions You've Sold

Retrieve and store completed auction data
without typing.

[Hack #65], it's vital for
every seller to keep permanent, off-site records of every single
auction he or she has sold.

This script, when run every day at the same time (as described in
[Hack #17]), does it all:

#!/usr/bin/perl
require 'ebay.pl';
$today = &formatdate(time);
$yesterday = &formatdate(time - 86400);
my $page_number = 1;
PAGE:
while (1) {
my $rsp = call_api({ Verb => 'GetSellerList',
DetailLevel => 8,
UserId => $user_id,
EndTimeFrom => $yesterday,
EndTimeTo => $today,
PageNumber => $page_number
});
if ($rsp->{Errors}) {
print_error($rsp);
last PAGE;
}
foreach (@{$rsp->{SellerList}{Item}}) {
my %i = %$_;
($id, $enddate, $title, $currency, $price, $highbidder) =
@i{qw/Id EndTime Title CurrencyId CurrentPrice HighBidder/};
if (! -e "$localdir/$id") {       
open (OUTFILE,">$localdir/$id");
print OUTFILE "[Details]\n";
print OUTFILE "enddate=$enddate\n";
print OUTFILE "itemnumber=$id\n";
print OUTFILE "title=$title\n";
print OUTFILE "price=$currency$price\n";
print OUTFILE "bidder=".$highbidder->{User}{UserId}."\n";
print OUTFILE "bidderemail=".$highbidder->{User}{Email}."\n";
close (OUTFILE);
}
}
last PAGE unless $rsp->{SellerList}{HasMoreItems};
$page_number++;
}

This script works similarly to the one in [Hack #85], but it retrieves a list of
auctions by seller that have ended between the
specified dates. Here are a few important things to note about this
script:

Unlike the GetBidderList API call, which is
limited to only 200 results, GetSellerList
supports paging, and when used properly, will continue to retrieve
results until you've got them all.

Since the DetailLevel input field (discussed in
[Hack #84]) is set to
8, the GetSellerList retrieves
all relevant information about an auction so we
don't have to issue separate
GetItem calls. This means we can retrieve the
auction details for hundreds of listings with only one or two API
calls.

The fields saved correspond to those listed in [Hack #65], with the exception of the
shipping charge (see below) and any fields you'd
normally enter manually (such as whether or not the bidder has yet
paid).

If you've specified a fixed shipping charge in the
listing or are using the Calculated Shipping option, you can retrieve
this information with the GetItemShipping API
call. Also of interest is GetShippingRates, a
non-item-specific function that helps determine the shipping rates
for different combinations of destination zip codes, package types,
weights, and shipping services.
