Changes in API Documentation: Clarification of the payerContractNumber Parameter Requirements
The payerContractNumber parameter is mandatory when the sender is the payer and uses a non-cash payment method. This ensures the correct processing of payments for delivery services.
If this parameter is not provided for shipments where the sender is listed as the payer, the system will automatically default to a cash payment method.
Previously, this information was not included in the documentation, which caused inconvenience for clients expecting non-cash payments.
Please review the updated description and ensure that your requests meet the specified requirements.
