Use this endpoint to retrieve a single transaction object by its TransactionId.

It works for purchases, refunds, and chargebacks, and is useful when handling webhooks, performing diagnostics, or tracking individual operations.

This is the most direct way to retrieve a transaction when its type is unknown or when you only need the specific object, not the full lifecycle.

📘
This endpoint returns only the transaction with the provided ID.
To retrieve the full lifecycle of a purchase, including related refunds or chargebacks, use GET Purchase Details.

For a complete explanation of transaction types, statuses, and structure, refer to the Transaction Guide.
