This method is designed to create a transaction batch within a single request or to create a single transaction. This method is asynchronous: the batch is registered upon request, and the actual transaction processing is performed by the system later. The payer and recipient parameters must contain encrypted data encoded in Base64 format. Encryption must be performed using the RSA algorithm with PKCS#1 v1.5 padding and the partner's RSA public key. To recover the original data, it must first be decoded from Base64 and then decrypted using the partner's RSA private key with RSA PKCS#1 v1.5 padding.
