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.
