Cannot pay self

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.
