@hunterachieng if you need to update the template please do it in a separate PR :)

And when you're ready for another review, please mark the PR as Ready

[hunterachieng]

@josephjclark We do not need to update the template as post is written correctly

[josephjclark]

Just a couple of small things!

[josephjclark]

Should we default this? Can users even us different domains?

If our implementation is on the main intuit.com baseUrl, we should default it and leave this as optional

[josephjclark]

changeset isn't needed for new adaptors - please delete this file and then we can merge
