Specifies an API call on our server.
Pick-to-Light URL Sections
Our Pick-to-Light technology works with your existing ERP or WMS or even Google Docs. A simple URL request, sent to our server on the Amazon Cloud, causes the associated Pick-to-Light device to light up with the operator’s name, SKU and quantity to pick – or any two lines of text!
Code Samples
These code samples will help you integrate the Pick-to-Light devices with your WMS or ERP. Need a closed-loop system (to confirm picks)?
Very Simple Perl Example using LWP
#
use strict;
use warnings;
use LWP 5.64;
my $browser = LWP::UserAgent->new;
$browser->cookie_jar({});
my $host = 'https://www.sku-keeper.com/'; # the host
$browser->post( $host,
[
'name' => 'yourusername', # the log-in ID
'pass' => 'yourpassword', # the password for the above ID
'form_id' => 'user_login_block'
],
);
$browser->get($host."api/E8D787:72D9D7/pick/hello/there/15,c5,4/10");
$browser->get($host."api/FFFE81:A42B35/pick/hello/there/15,c5,4/10");
$browser->get($host."api/FAAD4B:8E336A/pick/hello/there/15,c5,4/10");

Pick-to-Light Devices
Everything you ever wanted to know about batteries, (low) voltages, devices, mounting, device IDs, etc.
Check for the latest in AA battery prices at Slickdeals.
Double-sided tape can be purchased from Home Depot.
Turbos
Turbos connect the pick-to-light devices to the cloud. They are very easy to set up: just set your connection information and add your username and password. Turbos have a very useful GUI that does a great job helping you debug your system, check radio ranges, test communications, and see device parameters.
Using Pick-to-Light with Spreadsheets
Our Pick-to-light system is so flexible and easy to use that you don't have to integrate with a WMS/ERP - you can even use it with Google Sheets or Microsoft Excel.
Google Sheets
Pick-to-Light integration is so simple, you can even use Google Sheets for light-directed picking in any warehouse or distribution center!
Get your copy of the Free Pick-to-Light Spreadsheet and streamline your order fulfillment.

Even Microsoft Office can be used to activate our Pick-to-Light devices. A very simple Excel spreadsheet can be used to construct URLs for lighting up or storing data on the PTL devices. Just think about it: you could have PTL devices that continuously mirror the content of cells in a spreadsheet. Whoa! Suddenly, Pick-to-Light can be used in new ways throughout the supply chain.
Microsoft Excel is faster than Google Sheets, but both and be optimized for quicker response times.
