For our sample sync, we're going to be syncing to Chargify's Billable Events. In this case, we'll also need one more piece of information, the target Billable Event Stream's API Name. To get that, visit Chargify, click Events in the left navigation, and then Streams. You'll have to first create a stream if you don't have one. Once you've created it, copy and paste the stream API name.
