# Cash-In

Generate and manage inbound PIX payments. Supports standard QR Code and OpenFinance flows.


## Create Cash-In

 - [POST /cash-in](https://docs.connectpsp.com/apis/cash-in/createcashin.md): Generates a PIX payment intent.

Standard PIX flow: Returns a Copia e Cola string and a QR Code image (Base64) that your user can scan to complete the payment.

OpenFinance flow: Include the openFinance object to generate an OpenFinance payment link instead. The user is redirected to their bank's app to authorize the payment.

Once payment is confirmed by the banking network, ConnectPSP will POST a CASHIN_PAID event to your webhookUrl.

## Get Cash-In

 - [GET /cash-in/{id}](https://docs.connectpsp.com/apis/cash-in/getcashin.md): Returns the current status and details of a Cash-In transaction.

## Request Refund

 - [POST /cash-in/{id}/refund](https://docs.connectpsp.com/apis/cash-in/refundcashin.md): Requests a full refund of a paid Cash-In transaction (PIX Devolution via BACEN/SPI).

> ⚠️ Important: Only transactions with status PAID can be refunded. Partial refunds are not supported — the full original amount will be returned to the payer.

The refund is sent to the banking network synchronously. The 202 Accepted response includes the new endToEndId generated for the devolution (prefixed with D).

This endpoint requires the DigitalSignature header. See the Authentication Guide for details on how to compute it.
