You can always see how many people have clicked on any bitly-powered link by taking the link and putting a plus sign (+) at the end of it. For example: http://bitly.com/RYYpZT+
In this exercise, we'll review how to use the bitly API to programmatically get the same value.
Full documentation for the bitly clicks endpoint is here: http://dev.bitly.com/link_metrics.html#v3_link_clicks
The sample code is configured to make a call to the bitly /v3/link/clicks API endpoint with a link value, then returns the resulting JSON. You're looking for the link_clicks value -- that's how many people have clicked on this link.
Go ahead and swap the link parameter in the example for a bitly link of your own creation. How many clicks did it get? Click it and try again!
Now print just the number of clicks, but printing the value returned in ['data']['link_clicks'].
