Correct me if I’m wrong, but it looks like Fab won’t have any means to verify customers or purchases at launch?
I was planning to publish my Unity asset on Fab, but without a way to verify purchases, we won’t be able to integrate with our licensing backend. That would be a blocker.
Please consider adding a way to verify purchases. Anything that allows validating order/invoice numbers via a web API would work. For reference, here is Unity’s API: Unity - Asset Store Publisher API
I agree, having an API like that would be great!
Regardless of the engine or software the purchase(s) are intended for, a method to authenticate verified purchases of our products is a necessity.
Sure, sales reports are great for accounting - that helps very little combating piracy when it comes to support, or the time consumption required to collect and verify information from customers.
My studio already runs automated purchase validation services for Unity publishers. We hope to add Fab, but it doesn’t seem like an invoice verification API is a priority.
Hi everyone. We’ll have an integrated purchase verification solution when Fab launches. No need to consider adding it, as it’ll already be there. 
We also plan to eventually release a public API, but that’s a little farther down the road.
Hey, thanks for letting us know! So, at launch, we’ll only be able to manually verify via a publisher backend UI? That’s better than nothing, but it still won’t work for us, as we need an automated way to verify purchases. Hopefully, the public API won’t be too much farther down. 
Yes, you’re correct.
I’ve passed your API request on to the team. 
Looking forward to something usable.
I’m curious if there’s any movement on this as having even a basic API that we can do automated calls against would be extremely useful, and shouldn’t be difficult to build.
@Koderz there has not been any movement on this yet. We still want to build out an API, but right now we are focused on addressing the various usability features and improvements as listed on the roadmap. Once we feel we are in a good place with those we will look at the API again.
Lets’ be honest we all knew there wouldn’t be. Still hoping an unpaid developer does this for us 
Guys It’s been over a year since FAB released it isn’t THAT difficult to expose us the API that already exist. Especially considering that most plugins are distributed open source and there is ton of piracy going on around
I mean I don’t even understand what you guys are “looking at” this ■■■■ literally takes few hours to code up even accounting for complex authentication & API spam checking and whatnot like does might multi-billion-dollar company can’t even spare few hours of a random intern to provide such us such a critical feature?
Is there any news on “Purchase Verification API” in 2026?
We are trying to migrate from Asset Store to Fab store, and we would like to migrate our internal license verification system as well.
I’d like to bump this thread. It has been two years since a developer mentioned this feature was planned, so it should definitely be in the works by now. Any updates on the progress?
FABs development is being completely outsourced. And apparently they chose the worst possible company to do it, heck we still don’t have a functional search function.
The sad reality is that Epic doesn’t care, FAB is just an afterthought. With Fortnites profits decreasing, one can only hope that epic will be forced to realize how much goodwill they are currently wasting.
But I don’t see anything changing anytime soon. All we get is empty promises and the standard copy-pasted “I have passed this feedback & request along to the appropriate team.” response, with nothing ever happening.
