More Than 200K Subscribers to Open eBay Apps


The Open eBay Apps program now has more than 200K subscribers. And the number of eBay sellers that subscribe to the apps, which are embedded on the eBay site, is growing.

The numbers came from Tina Mazzei and Anand Gangadharan during a presentation at the PayPal X Developer Conference. I was excited to hear about the growth because I'm a contributor to the Open eBay documentation for developers. Tina explained to the audience that in the Open eBay program, "we bring the customers to you."

As Anand said, "eBay does a lot of the heavy lifting" for third parties. This includes handling marketing through the Apps Center and handling billing through PayPal.

The Open eBay apps include the new eBay Listing Analytics application, which is free.

Sellers use Open eBay apps right on the site. Many of the apps reduce sellers' operational costs. For third parties who want to write Open eBay apps, "the most important part is to be a customer-centric provider," and earn good ratings, Anand said.

Apps Center adds more marketing opportunites for Open eBay Apps!

Check out the latest marketing upgrades to the Apps Center, where sellers can find vetted apps to grow and manage their business! We've enhanced featured app placements to showcase more apps, and reduced the number of clicks to needed to subscribe. These apps are embedded inside of MyeBay, where sellers can directly access app functionality along side core MyeBay functions.

The Open eBay product team has also launched several recent product enhancements to help app developers better manage subscriptions. Most significantly, subscribers can now easily upgrade and downgrade between subscription plans.  

The feature list includes:

  • Offer easy upgrades and downgrades between subscription plans. Find out the pre-requisites, and how to opt-in!
  • Get notified every time a user's subscription state changes.  Especially useful for notifications for cancellation requests on non-prorated billing plans!
  • Get notified when a users auth token is revoked or renewed. Automate your end user messaging and detection of account synchronization problems.

Check out the Open eBay documentation for a complete list of the latest feature enhancements!
