How to set up the Flatpay terminal integration in Sapera so that payments can be completed on your Flatpay payment terminal.

## Flatpay

Flatpay is a payment terminal integration that lets you accept card payments directly from Pos via a Flatpay terminal. On this page you set up the connection to your Flatpay terminal and control how receipts are handled.

You need a company id and a terminal serial number, which are provided to you by Flatpay, before the integration can be used.

### How to find the settings

1\. Open the hamburger menu in the top left corner and select **Financial**. 2. Go to **Setup** → **Settings** → **Point of Sales** → **Agent application** → **Flatpay**.

Note that the settings are shown with English names in the screen. The setting names below are listed as they appear in Sapera.

### Activation

**Flatpay is enabled:** Turns the Flatpay terminal integration on or off. When it is off, payments are not processed via Flatpay. Default: No. Set to **Yes** to start using Flatpay.

### Connection to the terminal

**Flatpay company id:** The company id provided to you by Flatpay. It is used together with the terminal's serial number to send the payment to the correct terminal. The field is a number. A payment cannot be completed if the company id is missing.

**Flatpay terminal serial number:** The serial number of the Flatpay terminal itself, provided to you by Flatpay. It identifies the terminal that is to receive the payment. Required in order to complete a payment.

### Receipt and printing

**Flatpay receipt is printed together with sales receipt:** Controls whether the card receipt from Flatpay is printed together with the regular sales receipt instead of as a separate receipt. Default: No.

**Disable terminal printing:** Turns off printing on the Flatpay terminal itself. Select **Yes** if the terminal should not print a receipt itself. Default: No.

### Advanced

**Flatpay API to use:** Selects how Sapera communicates with Flatpay. You can choose **Async API with webhooks (Recommended)** or **Async API with polling**. The default is **Async API with webhooks (Recommended)**, which is also the recommended setting. Only use the polling mode if you have agreed on it with support.
