The page at http://predictionio.incubator.apache.org/datacollection/webhooks/ speaks about "Unifying Multichannel Data with Webhooks" saying that "Webhooks are used to collects data for your application from multiple channels automatically." Where can I get more details about these "webhooks" ? I'm thinking specially about the need to correlate user identities from separate data sources. Is there something inside the Event Server to work with that, or does that need to exist outside PIO?
Thanks Gustavo
