Yahoo opens up Web mail APIs

Yahoo is providing tools for external developers to create applications for Yahoo Mail.

Yahoo is opening up its Web mail platform to external developers, so that they can create plug-ins, utilities and applications for the popular Yahoo Mail service.

Yahoo plans to deliver application programming interfaces (APIs) for Yahoo Mail, said Chad Dickerson, head of the Yahoo Developer Network. The move comes on the heels of an announcement to offer unlimited storage capacity for Yahoo Mail users starting from May.

Yahoo officials had indicated in September of last year their intention to let external developers write applications for Yahoo Mail, and the tools will now be available at the Yahoo Developer Network Web site.

Yahoo provides similar development tools for other of its services, like the photo sharing site Flickr, the Yahoo search engine and the Yahoo Shopping product comparison site.

Yahoo rivals like Google also offer tools to third-party developers to build applications for their sites and online services. Companies like Yahoo, eBay and Google believe that it is to their benefit if external developers come up with useful and interesting applications for their online services that their internal developers don't have the time or resources to create.

With about 250 million users, Yahoo Mail has a gigantic audience, and the company is confident external developers will be very interested in writing applications for it, Dickerson said.

"By opening up our APIs, we'll begin to tap into the world's ideas about mail," said John Kremer, Yahoo Mail's vice president.

As an incentive for developers to use the Yahoo Mail Web Service to create applications, Yahoo will pay a commission of US$10 for every Yahoo Mail Plus account created as a result of a referral from an approved developer. Yahoo may come up with other monetary incentives and business models for developers, partners and independent software vendors.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
