So you need to send emails. Pretty simple right? Not so fast. It doesn’t matter how easy your language or framework makes sending emails, if you try to do it on your own be prepared to configure mail servers, setup Spam-related DNS entries, and still wonder if mail is actually being delivered. And your applications needs to process incoming email? Back to the config files, piping mail to your script - or just end up polling a POP or IMAP box. That’s what I had to do, back in the day. Fortunately, like so many things today, there’s an API for that. Actually there are a few.
We've added twenty six APIs to the ProgrammableWeb directory in categories including Messaging, Transportation, Location, and Open Data. Highlights today include an API that can provide developers with Uber driver information, and the Hypertrack.io API, for adding location tracking features to apps.
