# Overview

> Charge, authorize, capture, refund, void, and check status of card transactions.

<Info>
  [← Back to API Reference](/api-reference/overview)
</Info>

Submit card processing requests to a single API endpoint. Orchestra routes them to your chosen payment gateway, supporting [{supportedIntegrations} processors](https://orchestrasolutions.com/integrations/). Need one we don't support? [Request an integration](https://orchestrasolutions.com/integration-request/) at no cost.

## Key Features

* **Single integration**: Connect to any supported processor without separate integrations
* **Orchestration workflows**: Build routing logic, retries, and failover
* **Multi-tenant support**: Store merchant credentials via [Payment Gateway Accounts](/api-reference/paymentgatewayaccounts/overview) to process on behalf of customers
* **Flexible card input**: Send card details inline or reference a [StringToken](/api-reference/stringtokens/overview)

For gateway-specific parameters, see [Gateway Requirements](/guides/rest-api/gateway-requirements).
