# TourAction API-Requests of type "review"

Learn how to correctly structure the 'timings' array in API requests to avoid validation errors.

## Understanding the 'timings' Array Structure

When working with the Tour-Actions endpoint for reviews, it's crucial to understand the expected structure of the `timings` array. Incorrect formatting can lead to validation errors and HTTP 400 responses.

### Common Issue

A common mistake is passing a flat array of numbers instead of the required array of tuples. The `timings` field should be structured as an array of tuples, where each tuple represents a pair of numbers.

### Correct Structure

```
{
    "type": "review",
    "timings": [
        [1754374003, 1754402803],
        [1754460403, 1754489203]
    ]
}
```

Each inner array represents `[arrival_time, departure_time]` for a stop. Ensure that the number of tuples matches the number of stops in the tour.

### Troubleshooting

* Ensure the `timings` array is an array of tuples.
* Verify that the number of tuples corresponds to the number of stops.
* Check that the `type` field is correctly set to `review`.

Following these guidelines will help prevent validation errors and ensure your requests are processed correctly.
