@jonwaldstein I was checking the link you shared in the PR description and couldn't see any response with "YES". Usually, they only return "Y" instead - check the attached screenshot.

Also, I can see in this other link that they said that "YES" is used for the liability_shift property, but as you can see in the screenshot, they API responses are using the "Y" instead.

So, I'm a bit confused about the allowed values here and wondering if we should include the "Y" on this array as well.

Thoughts?

@glaubersilva good question! I chatted with our PayPal rep about this and they said we can simply use the liability_shift property to check for YES or POSSIBLE. However, as you pointed out there are a lot more responses we could check but that is completely up to what we want to support. To start, i'm happy to accept those simple values and reject the rest 😄
