Send webhook upon sending or receipt of email

Question

I have been looking around for how to create a webhook that is triggered when an email is sent or received in Gmail. For example someone sends an email, that email gets POSTed as a JSON object to one of my applications. I have found many middleman applications/services that do this (zapier offers all the functionality I want, but it costs money), but I can't find any documentation on how to actually do this myself so I don't need to pay for it.

Is this possible?

Solution 1

After some research the best solution I could find was to use the gmail API

To achieve the functionality that zapier offers you would have to have a service or something polling google and querying the status of a users in box. There are also a couple of ways to trigger calls to code, but I do not think this is what zapier does. Check the gmail API for more information.

Solution 2

You can try using context.io They allow you to connect multiple gmail (and others) mailboxes and then create webhooks for different actions. They handle the polling for you and then whenever the condition is met, they call the URL that you provide.
