REST API parameters

API parameters can be used with the REST API to filter, sort, and paginate results and to select fields and relations to populate. Additionally, specific parameters related to optional Strapi features can be used, like the publication state and locale of a content-type.

The following API parameters are available:

Operator	Type	Description
sort	String or Array	Sort the response
filters	Object	Filter the response
populate	String or Object	Populate relations, components, or dynamic zones
fields	Array	Select only specific fields to display
pagination	Object	Page through entries
publicationState	String	Select the Draft & Publish state Only accepts the following values: live preview
locale	String or Array	Select one or multiple locales

Query parameters use the LHS bracket syntax (i.e. they are encoded using square brackets [])

tip

Strapi takes advantage of the ability of the qs library to parse nested objects to create more complex queries. Use qs directly to generate complex queries instead of creating them manually.

Example using qs:

In the following example, the qs library is used to build the following URL: /api/books?sort[0]=title%3Aasc&filters[title][$eq]=hello&populate=%2A&fields[0]=title&pagination[pageSize]=10&pagination[page]=1&publicationState=live&locale[0]=en

const qs = require('qs');
const query = qs.stringify({
  sort: ['title:asc'],
  filters: {
    title: {
      $eq: 'hello',
    },
  },
  populate: '*',
  fields: ['title'],
  pagination: {
    pageSize: 10,
    page: 1,
  },
  publicationState: 'live',
  locale: ['en'],
}, {
  encodeValuesOnly: true, // prettify URL
});

await request(`/api/books?${query}`);
