Multiple accounts with 1 dev account/key set?

[d.b.metals]

I have 3 dev accounts. 1 for each eBay account I sell with. I'm not experienced enough to understand that I could have everything under 1 dev account.

How do I combine them? I only get 1 key set per developer account, right?

What am I missing here to fix this?

Hi @d.b.metals,

In the Application Keys page,  use Request another keyset to request an additional keyset for another application. When you request another keyset, you’re asking for an additional keyset for a different application, not a replacement keyset for an application that already has one.
