Set up API permissions for Express Checkout

[topgreengold]

I see 3 options:

- Option 1 - Grant API permissions to a third party to use certain PayPal APIs on your behalf.
- Option 2 - Request API credentials to create your own API username and password.
- Accept payments from your online stores before setting up APIs

As per the article you referenced, you want OPTION 2 - REQUEST API CREDENTIALS TO CREATE YOUR OWN API USERNAME AND PASSWORD

I have already chosed Option 2 - Request API credentials ...and completed setting in zen-cart admin accordingly.

But when I click Accept payments from your online stores before setting up APIs, 2 alternative shows up:
A. Accept PayPal payments before API permissions or credentials are set up
B. Block payments from uncredentialed shopping carts

And then I have already submitted A. or B. several times, but not sure what it will cause?

If you've already set up your API credentials, then WHY are you bothering with clicking on "Accept payments from your online stores before setting up APIs"?
Ignore the "Accept payments from your online stores before setting up APIs" thing, because you've already set up API stuff. You're no longer in the "before" state.
