You can use the same credentials for your existing Stripe account to configure your payment processor in NationBuilder, but they will not connect. Even though processing payments through NationBuilder is powered by Stripe, the integrated payment processor is a completely separate processor. 

You'l also notice that the experience of using the processor in NationBuilder differs from what you would experience using a Stripe account externally: 

1. The dashboard is different. You will have access to what Stripe refers to as their "Express" dashboard, which includes basic payout and account management details. 
   
   
2. The payment data displayed in the dashboard will only include contributions that have been made through your NationBuilder account. Donation information you have access to in your current Stripe account will not be displayed. 
   
   
3. You can continue to access your Standard stripe account after you've configured your NationBuilder integrated payment processor. You will only be able to access the payouts dashboard for your nation directly through the control panel. Your Standard stripe account will not track any donations submitted through NationBuilder even if you're using the same login credentials for both accounts.
   
   
4. You will not be able to connect your payment processor in NationBuilder to an external applications. Donations through this processor will need to be processed through your NationBuilder account.
