Webhooks

[Chris Chapman]

Hi Jerry - 

Without loading some sort of content from a webserver containing identifying information, such as a UUID, I don’t see how any other way web hooks could be implemented. Looking at the mailchimp api, it seems they are handling the web bug functionality internally in their application THEN transmitting the data to your script on a server somewhere. So essentially it’s the same thing, they are just acting as a middleman.

Now for tracking bounces, usually the return email is set to something like emailAddress+bounces at domain.com <mailto:emailAddress+bounces at domain.com> or uuid+bounces at domain.com.  These go into a bounces mailbox which is processed.  I assume this is how mailchimp handles it as well. Maybe not a mailbox per se but a process which accepts return mail headers.

Hope this helps.

That URL points to a script on a server that does a database insert based on the UUID and returns headers which return an image file.
