An update to the Overwatch League App accidentally gave fans full access to the esport league’s API.

The app gives fans details on the current state of the Overwatch League, and this update was only meant to add a few extra statistics. But on top of individual map stats listing player contributions to kills, damage and healing, the update also brought a whole host of minutiae through the League’s API.

The leak revealed stats ranging from objective time and critical hits, right down to the number of shots fired and those that hit their mark. It’s a bit of a statistician’s dream, but the Overwatch League has confirmed that this goldmine of numbers was never meant to be dug up.

“In a recent update to our mobile products, we unintentionally deployed access to an expanded stats API in the code,” said Overwatch League commissioner Nate Nanzer, speaking to the competitive Overwatch subreddit.

”You guys are on the ball and quickly discovered it. While we appreciate the enthusiastic response, that content was not intended for public consumption at this time, and we’re going to turn it back off.”

The Overwatch League’s continued success is helping the overall esports market balloon in popularity - reports predict the worldwide esports market will hit $2.17bn by 2023.
