HttpGet API Endpoint Accepting Array Parameter

I have an endpoint for an HttpGet method:

    [Route("fightIds")]
    [HttpGet]
    public async Task<IActionResult> GetPredictionsByFight([FromQuery] IEnumerable<int> fightIds)
    {
      var predictions = await _predictionService.GetPredictionsByFights(fightIds);

      return new OkObjectResult(predictions);
    }

    [Route("fightIds")]
    [HttpGet]
    public async Task<IActionResult> GetPredictionsByFight([FromQuery] IEnumerable<int> fightIds)
    {
      var predictions = await _predictionService.GetPredictionsByFights(fightIds);

      return new OkObjectResult(predictions);
    }

Is it best practice to use [FromQuery] and accept the values as part of the URI? If so, what's the best way to build this request URI for my HttpClient? Do I need to manually concatenate a string, e.g. 'https://localhost:7109/api/Predictions/fightIds?fightIds=1&fightIds=2'? This feels like I'm doing something that is bad practice here. Or should my endpoint be accepting [FromBody] or some other way?

Array in Query can cause problems. What if there will be 300 items ? HttpPost with Body is fine

Thanks - I'll implement it with a body instead!
