Introduction

Hello! Welcome to the Walker Tracker API. This page is for you if you are a programmer / developer /tinkerer who would like to have access to Walker Tracker data in order to

Re-visualize it
Include it in your own application
Create widgets, feeds, etc

NOTE: the API is only accessible to our community members if they've explicitly listed themselves as 'public' in their preferences. If you have an interest in API access for your private program - please contact us

You'll use HTTP GET requests and REST (representational state transfer) to get data from the API

A Walker Tracker API request might look like this:

yoursite.walkertracker.com/api/Athena.xml/view/20070514

*note - browsers show xml unequally. If it comes back as a single paragraph, view the source.

What's happening here?
We're telling Walker Tracker

to send us a single step blog/count day (May 14th, 2007 = 20070514)
for username 'Athena'
send the response in XML

Go to the examples to see more.

Currently the API is read only - a future version will include the ability to add step counts, etc.

Methods
