# Insert Data

> You can insert new data using the POST method

To create a row post a JSON object whose keys are the names of the columns you would like to create. Missing properties will be set to default values when applicable.

```bash theme={null}
curl "https://integration.getmateo.com/api/v1/contact" \
 -X POST -H "Content-Type: application/json" \
 -d '{ "full_name": "Max Mustermann" }'
```

```bash theme={null}
HTTP/1.1 201 Created
```

No response body will be returned by default but you can add a `select` query parameter to select the columns that should be returned:

```bash theme={null}
curl "https://integration.getmateo.com/api/v1/contact?select=full_name,birthday" \
 -X POST -H "Content-Type: application/json" \
 -d '{ "full_name": "Max Mustermann" }'
```

```bash theme={null}
HTTP/1.1 201 Created
```

```json theme={null}
{
  "full_name": "Max Mustermann",
  "birthday": null
}
```
