Does anyone know of any resources that can link me to how to use webhooks? I'm pretty new to this and I think this will add a lot of functionality to for our system...I just don't know what they're capable of yet.
Marketo doc does a pretty good job: http://developers.marketo.com/webhooks/
Yep, the docs are the place to go it is fairly straightforward to use them (be wary however if your webhook returns XML as Marketo does not support reading Element attributes). Also be aware that Webhooks are prioritized lowest in the queue when it comes to processing so backlogs and or slowness can occur if you are doing them in large batches.
You might read this blog post on one of the finer points of webhooks. In there, I make mention of one fundamental rule: field updates from webhooks will not be available until a Data Value Changes event has been triggered on the field. That is, updates are not available in the next step in the flow.
More webhook-tagged posts to come on my blog.
