How do I remove restrictions on my Bitcoin/Coinbase OAuth application?

[laredotornado]

I'm trying to use the Coinbase API for Ruby to create an application to accept Bitcoin payments. I assume one way I can use their API is through their OAuth sequence. So I created an OAuth 2 application on their site. It has these scope restrictions by default ...

• wallet:transactions:send is limited $1.00/day per user
• wallet:transactions:send:bypass-2fa is disabled

with a link that reads "Please verify your identity to upgrade limits." When I click on the link, it gives me two options

Buy limits (where I can upload my ID) or
Sell limits (where I'm given a link to "Verify my Identity")

Which of these do I need to use in order to achieve what I want?
