OnePageCRM has the ability to output changes via a webhook. What I would like to know is how can I setup Elasticsearch to receive the post (or more importantly transform it) from the OnePageCRM format to the ES post format.
All I can think of at the moment is to set the URL to be the destination index and post blind without structural changes. I would normally use the _bulk tail on index, but I wondered if I could go for straight index post request as it should only be triggered from changes.
