Why did I get the error "Account not found. Unilateral receiver not allowed in chained payment is restricted" when testing the chained payment on my site?

Important: Adaptive Payments is now a limited release product. It's restricted to select partners for approved use cases and shouldn't be used for new integrations without guidance from PayPal.

PayPal presented an "Account not found. Unilateral receiver not allowed" error message.

This usually occurs when the receiver has an unconfirmed email address.

Ask the receiver to confirm their email address. Here’s how:
  1. Access your PayPal email settings.
  2. Select the email address you'd like to confirm.
  3. Confirm the selection and we'll send you an email.
  4. Follow the link in the email to complete the confirmation process.
