# Quick start

<BraEng />

This guide shows the process of executing a pre-authorization, using Carat Portal's REST web service interface.

## Requirements

- Active account on Carat Portal's homologation environment (obtained with our support team)
- A tool capable of performing HTTP calls, such as Postman, REST Client or cURL

## Creating the Pre-Authorization

**HTTP method**: POST

**URL**: https\://<URLPOSTMAN/>/e-sitef/api/v1/transactions

**Headers**:

- **Content-Type**: application/json
- **merchant_id**: {your merchant id}
- **merchant_key**: {your merchant key}

**Request**:

To use this example, remember to set the variable `{{url}}` to the value<br/> **<URLPOSTMAN/>**

<!--DOCUSAURUS_CODE_TABSS-->

<!--JSONN-->

To use this example, don't forget to define the variable `{{url}}` to the value<br/> **<URLPOSTMAN/>**

```json
{
  "order_id": "orderID",
  "merchant_usn": "20190101",
  "amount": "100",
  "transaction_type": "preauthorization"
}
```

<!--cURLL-->

```curl
curl
--request POST "https://{{url}}/api/v1/transactions"
--header "Content-Type: application/json"
--header "merchant_id: xxxxxxxxxxxxxxx"
--header "merchant_key: xxxxxxxxxxx"
--data-binary
{
    "order_id":"orderID",
    "merchant_usn":"20190101",
    "amount":"100",
    "transaction_type":"preauthorization"
}
--verbose
```

<!--END_DOCUSAURUS_CODE_TABSS-->

**Response**:

```json
{
  "code": "0",
  "message": "OK. Transaction successful.",
  "pre_authorization": {
    "status": "NOV",
    "nit": "1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqr",
