This endpoint creates a Transaction. It should only be used when decryption activity occurs outside of the Decryptx platform. Certain Partners may operate their own Validated P2PE decryption environment (Domain 5). This allows the partner to journal their decryption activity into the P2PE Manager, allowing the Partner to utilize the P2PE Manager for their device management and chain of custody. The Partner's Client can still benefit from the device management, chain of custody, and historical decryption activity even when decryptions occur outside of the Decryptx system.
