The Message Faces provides users the ability to integrate the service into their applications. Message Faces is a service that provides users with images of the people who send email in order to enrich email inboxes or address books. With Message Faces users can recognize who is sending email immediately from their personalized photo icon, and distinguish which emails are important. Currently Message Faces supports Yahoo!, GMail, Apple Mail, AOL, GMX, web.de, Mozilla Thunderbird and Roundcube. The API is currently in Beta. The API uses RESTful protocol and responses are formatted as PNG files.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
