The official documentation can be found here.

Is there a way to fetch custom filters for a particular category in Magento 2 using Rest api?

I am using the url below to fetch the products in a particular category and it works fine.

/rest/default/V1/products?searchCriteria[filterGroups][0][filters][0][field]=category_id&searchCriteria[filterGroups][0][filters][0][value]=262&searchCriteria[filterGroups][0][filters][0][conditionType]=eq&searchCriteria[filterGroups][1][filters][0][field]=visibility&searchCriteria[filterGroups][1][filters][0][value]=4&searchCriteria[filterGroups][1][filters][0][conditionType]=eq&searchCriteria[pageSize]=10&searchCriteria[currentPage]=0

The only issue is that I would like to show filters based on the categories selected. For eg a price filter works for every category but a size and color filter would only work for clothing category while screen size would work for electronics.

Any idea on how to fetch the filters for each category?

    I found the answer ,but I had to switch from using rest api to graphql as graphql supports aggregations . This was exactly what I needed and also seems like graphql has more features as compared to rest api for magento 2.

    You can try magento search api to get filters by passing category or any other field like below example.

    {{url}}/rest/V1/search?searchCriteria[requestName]=catalog_view_container&searchCriteria[filterGroups][0][filters][0][field]=category_ids&searchCriteria[filterGroups][0][filters][0][value]=10

    Result will have category and other buckets, something like below:

    [
  {
    "name": "category_bucket",
    "values": [
      {
        "value": "2",
        "metrics": [
          2,
          634
        ]
      },
      {
        "value": "10",
        "metrics": [
          10,
          634
        ]
      }
    ]
  },
  {
    "name": "brand_bucket",
    "values": [
      {
        "value": "617",
        "metrics": [
          617,
          562
        ]
      },
      {
        "value": "639",
        "metrics": [
          639,
          29
        ]
      },
      {
        "value": "1218",
        "metrics": [
          1218,
          26
        ]
      },
      {
        "value": "640",
        "metrics": [
          640,
          8
        ]
      },
      {
        "value": "1332",
        "metrics": [
          1332,
          4
        ]
      }
    ]
  }
]

    You can map this result with attribute api result to get label
    {{url}}/rest/all/V1/products/attributes?searchCriteria=&fields=items[attribute_id,attribute_code,options,frontend_labels]
