| - Duplicate reference: The transaction or billing agreement attempts to reference the sender and receiver of payment as the same entity, which is invalid. | - Disrupted transactions: PayPal prevents the transaction from being processed to avoid misuse or fraud stemming from potential self-payment. | - Confirm separation: Ensure that the sender and receiver are different entities.
- Review API request: Ensure you use distinct PayPal account IDs or email addresses for the sender and receiver.
- Implement validation checks: Ensure that your application checks to prevent users from setting up billing agreements with duplicate entities.
- Debug application code: Review and debug the code to correct issues leading to payer and payee using the same account. |
