Here's how to enable PayPal Payments Pro on a Sandbox test account:
- Log in to your PayPal Developer account.
- At the top of the page, click Dashboard.
- Click Accounts under Sandbox on the left side of the page.
- Click the email address for the account for which you would like to enable Payments Pro.
Note: Only Business accounts can have Payments Pro enabled. - Click Profile under the email address.
- Click Upgrade to Pro.
- Click Enable.
Once your sandbox business account is upgraded to PRO, you should be able to integrate and perform DoDirectPayment API calls.
Thank you so much for your patience and understanding.
Sincerely,
Chiranjeevi
