So how does it work?



Initiate Transaction Verification

As a developer you simply call the Okay API with the transaction verification call from your service!



Customer Gives Okay

The customer receives a push notification within the Okay app. He can then see the details of the transaction and give his Okay.



Transaction is Verified

Once the transaction is verified, you are sent back confirmation of this. All transactions are fully traceable and PSD2 compliant! Sweet!
