# Smart Transfers Sandbox

The easiest way to try this product is by using the sandbox connector. To do that, you need to create a Smart Transfer preauthorization using the following payload:

```shell
curl --location 'https://api.pluggy.ai/smart-transfers/preauthorizations' \
--header 'Content-Type: application/json' \
--header 'X-API-KEY: YOUR TOKEN' \
--data '{
  "connectorId": 600,
  "parameters": {
    "cpf": "xxxxxxxx"   // put a valid CPF here
  },
  "recipientIds": [
    "xxxxxxxxxx"         // put a valid recipient id here
  ]
}'
```

To log in to the mock bank, you can use any username and password -- any combination will work. Once the authorization is complete, you can schedule all the payments you need.
