Developer Discussions

I have implemented the checkout and I want to manage the payment transactions but all the endpoints under it returns "K007 - Invalid Key Scope". I have confirmed that I am using the correct secret key for these endpoints and yet it doesn't work. I generated the API Keys in Maya Business Manager under the developers tab, I had created an application there and I chose the "Checkout". Is managing payment transactions endpoints not included in the scope of "Checkout" API Keys?
