# Cardano - Transaction Manager API

> Streamlined Cardano transaction submission and monitoring with turbo features, webhooks, and historical tracking for reliable transaction processing.

The Transaction Manager API provides a streamlined way to submit, monitor, and manage Cardano transactions with advanced features like turbo submission, webhook-based monitoring, and historical tracking. Designed for applications that require reliable transaction processing, it ensures your signed transactions are quickly propagated through the network while giving you real-time visibility into their state.

Whether you’re building wallets, payment processors, or DeFi protocols, the Transaction Manager API abstracts away the complexity of low-level transaction handling, offering secure, high-performance endpoints for transaction submission and lifecycle monitoring.

## Key Features

* **Standard Transaction Submission**: Submit already serialized CBOR transactions to the Cardano network for processing.

* **Turbo Transaction Submission**: Accelerate transaction propagation with Maestro’s Turbo Submit feature, including built-in monitoring.

* **Transaction State Retrieval**: Query the current status of a transaction by its hash to check whether it’s pending, confirmed, or failed.

* **Transaction History**: Retrieve paginated records of previously submitted transactions for your project.

* **Webhook Integration**: Set up webhooks to receive push notifications on transaction updates, confirmations, and failures.

* **Multi-Network Support**: Access the same functionality across Mainnet, Preprod, and Preview environments.

## Key Benefits for Developers

The turbo submission feature helps ensure transactions are quickly included in blocks, while webhook-based notifications let your applications react to status changes in real time. By providing a unified API for submission, tracking, and history retrieval, it enables faster development cycles, reduces operational complexity, and ensures consistent transaction performance across Cardano environments.
