You should post array of integer in body.

If you are using jquery to do the post, you can do something like below.

$.ajax({
  type: "POST",
  url: url,
  data: [1, 2, 3]
});

In your Api -

public HttpResponse Post(int[] ids){}

the problem is length of params, as i mentioned the params are about 1000 URL and earch url is 100 character length, so easily exceeded the 2048 URL length limitation – SnowStorm Aug 13 '15 at 20:07
If you do a HttpPost it will not hit the url length limit. I think it is hitting the url max limit as you are passing parameters in the url to Http GET method – Yousuf Aug 13 '15 at 20:18
but if HttpPost used, how the results(in this case array of URLs) is returned? – SnowStorm Aug 14 '15 at 04:46
Instead of returning HttpResponse, you can return list. you can return list type from a post method. – Yousuf Aug 14 '15 at 14:09

You need a post method in your controller. And receive an array of strings.

public IEnumerable<Category> GetCategories([FromUri] int[] categoryIds)

and send request

/Categories?categoryids=1&categoryids=2&categoryids=3

Then in your method do the calculations and return a result as usual

I need to pass about 1000 URL and each URL length is about 100 character, thus total webapi params length reach about 100,000 character that is more than standard URL length – SnowStorm Aug 13 '15 at 19:54
Is just an example, you can also pass an object to your api as string[] using Jquey AJAX function. – Juan Carlos Oropeza Aug 13 '15 at 20:06
