    Accepted Solution


    login to the Paypal account and make sure the billing agreement has been confirmed. Please do the following:

    1. login to your Sandbox
    2. then go to Merchant Services
    3. Choose Website Payments Pro from the left navigation
    4. Choose Accept Billing Agreement from the RIGHT of the page

    Without this billing agreement being accepted you WILL continue to get this 10501 error... rediculous! No where does this Sandbox or whatever tell you where to find this information. So, if you don't want to lose your mind please follow these steps.

    Also, please check the following links for your clarification.

    Hope it may helpful to you.
