Your API key looks a bit short...

Did you just register your API key? According to Eugene O'Neill on this forum:

After registering an API key and specifying a valid domain, it may take up to 30 minutes for the changes to take affect, so if it doesn't work immediately, go grab a coffee and check back in a few.

Also, make sure you specified your API Domain.

He outlines the full series of steps as follows:

To register an API key:

head over to https://www.linkedin.com/secure/developer

log in and click the link to Add New Application

fill out the following info:

• Company (choose from the dropdown)

• Application Name (e.g. My Company Jobs)

• Description (e.g. For receiving applications from job applicants)

• JavaScript API Domain (this is an important step. this is the website the button will go on e.g. http://www.mycompany.com)

• Application Use (select one from the list, if nothing matches your needs, choose "other")

• Developer Contact Email (your email address)

• Phone (a phone number you can be reached at if there are issues with the account)

check "I agree" Security text (enter the characters you see just above it)
