Cannot pay self

Returns from the Payments V1 API.

CANNOT_PAY_SELF indicates that the payment request is attempting to send money to the same account initiating the transaction.

Cause	Impact	Resolution
- 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.
