Authorize.net and paypal

[hannahcochran]

I am trying to implement paypal express-checkout with authorize.net.

I already did the Authorize.net process

1. login with my sandbox account
2. Account option
3. Digital payment solutions
4. PayPal (sign up)
5. login with paypal sandbox
6. grant
7. redirected to authorize.net
8. status pending after more than 3 days.

I tried to gave access to authorize.net in paypal but when I entered the authorize.net Api Login it told me tha is invalid.

have somebody else had the same problem? Do I need to add something else to the api Login?

Thanks id advance for your help

I don't think I need a Union for what I'm doing. Could someone help me out with this?
