JSON:API Resources is Drupal 9.1 compatible

Published on

JSON:API Resources is now Drupal 9.0 and 9.1 compatible with the 8.x-1.0-beta4 release! If you are not familiar with this module, it is essentially the sandbox contributed project for building the extensibility layer for Drupal's JSON:API implementation. That is a fancy way of saying it lets you define custom endpoints that leverage the JSON:API specification.

We shipped the module with a requirement of  as we required some code that would ship in Drupal 8.8.0. Howevever, we never released the fix for the file to allow installation of th module with Drupal 9!

I made a commit nine months ago fixing it. But I never got around to making a release 😬.

git commit diff fixing drupal/core requirement

This is a pretty big deal because it unblocks most of (the entire?) JSON:API contrib ecosystem for Drupal 9 support. You couldn't use JSON:API Search API, JSON:API Views, and more on Drupal 9.

This release also comes with a fix to be compatible with 9.1.0! The  class used to implement . It does not in 9.1.0 and instead there is  a new  response class. Here's the change record: https://www.drupal.org/node/3163310

I also tagged a new release of JSON:API User Resources (8.x-1.0-alpha4.) This included a fix to the module to make it Drupal 9 compatible. This module supports user registration and password resets over JSON:API.

The JSON:API Search API needs some updates in the tests – https://www.drupal.org/pift-ci-job/1921557. But it should be fine on Drupal 9, as the failures are related to test specific items.

The JSON:API is now part of Drupal Core.

The JSON:API specifications defines standard query parameters to be used to do filtering, sorting, restricting fields that are returned, pagination and so on.

This module provides a helper Class to create the required query. While doing so, it also tries to optimise the query by using the short form, whenever possible.

API Reference


Install the package via :

$ npm i drupal-jsonapi-params



Import from

getQueryString [options?]

Returns query string which can be used in api calls. By default the output is URI encoded. Options can be passed to control the qs.stringifying internally used.


Used to restrict items returned in a listing.

pathA 'path' identifies a field on a resource
operator(Optional) An 'operator' is a method of comparison
group(Optional) Name of the group, the filter belongs to

Following values can be used for the operator. If none is provided, it assumes "" by default.

NOTE: Make sure you match the value supplied based on the operators used as per the table below

Value TypeOperatorDescription
, , , , , , , ,
size 2, The first item is used for min (start of the range), and the second item is used for max (end of the range).

Being able to retrieve resources from an API is a fundamental first step.

In this tutorial we will learn how to:

  • Issue an HTTP request to extract information about a node from the JSON:API server
  • Examine the response from the server

By the end of this tutorial you should know how to use an HTTP Get request to return a resource from the JSON:API server, and know what the default response for the resource will contain.


Request a node from the JSON:API server using an HTTP Get request.


JSON:API Resource Requests

GET your node

JSON:API is a specification that follows the REST principles. The benefit of building a RESTful web service is that you can leverage established patterns that are well known and battle tested. One pattern tells us that once you know the URL for your resource, you can access any item in that resource by appending the ID in the URL.

Construct a resource URL

According to the information provided by the entry point at /jsonapi one of the resources available to us is:

In order to get a specific article we will need to append the resource ID to the end of that url:

Extract the UUID for the node

The JSON:API module in Drupal uses the UUID field in the entity as the resource ID. There are different ways you can get the UUID from a particular article -- one of those being JSON:API -- but for now we will use the Devel tab that's added by the Devel module in the node page.

Use the Devel tab to find the UUID of a node

Request the resource

Once we have the UUID we are ready to make the HTTP request to fetch the information about the article.

That will return something like:

(We've abbreviated this response for readability.)

Drupal will respond to that request with a JSON object that contains information about the attributes and relationships of that particular article.

The JSON:API format

An example of a JSON:API response

The responses from the JSON:API module will always follow the structure defined in the official specification. One of the advantages of this specification is that it's very intuitive and easy to read. You can see that there are four different sections in the JSON:API responses:

  • Resource data information: Identifies a resource entity using the resource type an the resource ID.
  • Resource content: Contains the actual data of the resource, attributes and relationships.
  • Metadata: Provides additional information about a resource or a respose that is not considered content, but enables meaningful interactions in the consumers.
  • Glue structure: Allows to connect the different pieces together. It does not provide any information, but makes parsing the response easier for the consumer libraries.

    There are four different sections in a JSON:API response


In this tutorial, we made our first request to retrieve actual content from the Drupal backend. For that we had to find the resource URL for the article content type, and the UUID field of the article node we wanted to fetch.

Drupal jsonapi

Drupal 8 jsonapi: How to change the structure of returned json relationships included array?

I am sending a request to the jsonapi node endpoint, and using the following parameter to include the "relationship" objects of those nodes for user (post author data) and user picture (avatar):


This returns to me the json data of the nodes as well as all of the relationship objects lumped together (regardless of type) into the "included" array. The included array ends up looking like this by default:

Context: We are trying to integrate jsonapi with an iOS app as the client/consumer.

My Problem: It's difficult to write up data models in the iOS client for these relationships (without looping and sorting every response) since they are all lumped into the same level of the "included" array. Also a problem is that each "type" will have its own set of attributes/fields so data models in iOS need to be built based on "type".

Question: Is it possible to change this structure so that all included objects are sorted by type?

I would like for the "included" array to be indexed by "type" where all objects of that type would be inside that index. Maybe something like:

I'm assuming this would require a custom module with some sort of hook where I could loop and sort the data before returning it to the iOS app. But, haven't been able to find any documentation on this type of json response modification.

Any help would be much appreciated.

How to configure JSON API module and create web services using JSON API specifications in Drupal

There are two ways to create you can create web services in Drupal. one is using the Core Rest Web service module and the other is using the JSONAPI module.

Here we are going to discuss one of the important modules available in Drupal which is used for creating web services called JSON-API module.

You can read more about the configuration of the Core Rest API module here

In this article we are going to discuss below points

  • What is Json API
  • When you have to use JSON API over Rest API
  • What Json API cant do
  • Installation and configuration of JSON API module and JSON API extras module
  • Retrieve resources using  HTTP GET method
  • Post Content with HTTP basic Authentication
  • Updating existing resource(PATCH)
  • Delete existing resource
  • Uploading Files using JSON API
  • Logout API
  • Fetching multiple resources in a single request using Json include
  • Retrieving single resource
  • Sorting resource collections
  • Filtering
  • Filter based on multiple conditions and multi-value fields

Before discussing more about the module, we are going to discuss what is JSON API specification.

What is JSON API?


Json API is a specification for how a client should request a resource that to be fetched or modified, and how a server should respond to those requests

JSON:API is designed to minimize both the number of requests and the amount of data transmitted between clients and servers.

Robust approaches to resource relationships and common query operations such as pagination and sorting

JSON: API requires the use of the JSON: API media type (application/vnd.api+json) for exchanging data.

The below headers should be sent.

Accept: application/vnd.api+json

Content-Type: application/vnd.api+json

Also JSON: API has specific response codes for each type of response. Drupal JSON API uses a subset of that.

  • 200 OK – All successful GET and PATCH requests
  • 201 Created – All successful POST requests (response includes the newly created resource)
  • 204 No Content – All successful DELETE requests

When you have to use JSON API over Rest API

In JSON API by default No configuration/little configuration is possible.

Using the JSON API extras module we will get some more configurations. We are discussing more about this latter in this article.

When enabling the JSON API  module a Rest API will be available for every entity type and bundle.  This can be accessed from a dedicated URL using HTTP methods.

Resource collections

possibility of retrieving multiple resources using JSON API collections. Simply use a simple URL to load a collection of nodes. But in Core Rest API, you have to use view Export to load all.  for example, load all articles using a Get request with URL below


You can use different kind of filters here

/jsonapi/node/article?page[limit]=25&page[offset]=25 You can include multiple entities and resources in a single API response, This will reduce the number of requests to the server.

Throughout this article, we are using claro (https://www.drupal.org/project/claro) theme as the administrator theme.

What JSON API can’t do

JSON: API is entirely entity-based. That is, it can’t process business rules or do things which can’t be thought of as “CRUD”. Business logic, like registering a new account, logging in a user, or requesting a new password is not part of JSON: API. Many of these are already provided by Drupal core.

Installation and configuration of JSON API  module and JSON API extras module

Navigate to the modules listing page(Extend menu) and enable modules as below.

Even though JSON-API module is a non-configurable, you can see below to option in under configuration –>Web services->Json API


JSON API extras module

Json API extras module provides more configurations.

Module link – https://www.drupal.org/project/jsonapi_extras

This module provides below configurations additional to the default configuration of JSON API

  1. Enable and disable resources.
  2. Overwrite the name of a resource. Example: article instead of node–article.
  3. Overwrite the path for a resource: Example: /api/articles instead of /jsonapi/node/article.
  4. Disable fields.
  5. Use field aliases. Example: tags instead of field_tags.
  6. Enhance field output. Example: Use the date_time field enhancer to format date fields.


Go to configuration ->webservices – JSON API

You can see additional tab for Extras configuration.

In settings, you can change start URL of API. By default, it will be JSON API.

In the resource override tab,  you can see all resources.

By click on the overwrite button, you can change each resource path and field alias of resources.

By click on advanced, you can further customize each field and we can decide the label name of the field in the response.

Retrieve resources  using  HTTP GET method

if an anonymous user has read permission for an entity or entity bundle, you can access results by putting URL in the browser or using any API client.

URL – http://localhost/drupal9/jsonapi/node/article

URL with restricted number- http://localhost/drupal9/jsonapi/node/article?page[limit]=5

Here we are displaying contents of type article. Here it will display all published and unpublished nodes. We will discuss later in detail to filter the result based on various conditions.

See the below result in Postman.

Post Content with HTTP basic Authentication

For operations like post/put/delete , we have to do additional configuration.

First, confirm below configuration is enabled.

Next, we are going to enable HTTP Authentication.


Next, we need to create a new role and assign a user to this role.

I have created new user with user name – apiuser and assigned roles API user to this user

Also  Enable Article:Create content permission for this particular user.

Open your postman again and provide below as body text.






      "title":"article 1",


        "value":"some body text",






And for authentication, provide newly created apiuser details in Authorization tab.

As a post response, you will receive newly created content details in data objects.

So at the backend, you can see newly created content.

Content type header

Make sure your content type header is as provided below.


Updating existing  resource(PATCH)

We need to pass resource id to update a resource. So here for updating article content we have to pass article  UUID.  You can get UUID from the results of  /jsonapi/node/article or you can get Devel tab of edit article node.

You can download devel module from drupal.org – https://www.drupal.org/project/devel

URL- http://localhost/drupal9/jsonapi/node/article/{UUID}


Request body

You will receive a response with updated article details.

Delete existing resource

URL- http://localhost/drupal9/jsonapi/node/article/{UUID}

Just pass the UUID with authentication headers or Xcrsf token header.

Confirm whether  resource  is being  deleted or not from the admin content  http://localhost/drupal9/admin/content

Uploading Files using  JSON API

In order to upload files we are first going to generate CSRF token. This needed as a request header while sending files. Here we are testing this using javascript code. we are not using POST man here. We can easily test file upload using post man because it has a file browse option as shown below.

GET CSRF token




“csrf_token”: “EC2LuRmDRCPV6oYvpRn_W-YXQjMkfSdHgDgEbspti8I”,

If you try to login again, you will get 403 – access denied. You either need to logout or clear the SESSIONS table.

There are a lot of issues reported in the community while uploading an image.  All will follow the below method where users will see a blank image at the back end.


POST/jsonapi/node/article/field_image HTTP/1.1





[…binary file data…]

So the back end in /admin/content  page Files tab image will look as below

The basic reason for this issue is many people equating Binay with base 64. Actually we don’t want to convert to base6 4 while sending it to the server. You can directly send a file object to the server.

See below the working code where I am uploading the file.

If you are using Jquery/any other javascript plugin , use fetch() to call API.

HTML code

<div class="container">



  <form action=""name="registration"id="first_form">


    <input type="file"id="myfile"name="myfile">


    <button type="submit"id="#sbbutton">Register</button>







Javascript code


































fetch('http://localhost/drupal9/jsonapi/node/article/field_image',{// Your POST endpoint






        'Content-Disposition':'file; filename="filename.jpg"'


    body:myInput.files[0]// This is your file object


    response=>response.json()// if the response is a JSON object


    success=>console.log(success)// Handle the success response object


    error=>console.log(error)// Handle the error response object





In admin content you can see uploaded file in the files tab.

This is a kind of temporary storage. You have to use files file id received in response with entity add API.

The response of the file upload will be as below.

Now I am going to create new article with this file id.


in the body of the request include file id as well.



































"alt":"Json Uploaded Testing1",

"title":"Json Uploaded Testing1",










Provide headers as below.

You can see below the success response with created node details.

See the below content with the image at the backend.

Logout API

you can logout from Drupal using the logout token you received during login.

Just use the below URL as a GET request.


  • {siteurl}/user/logout?_format=json&token=dBqI0_DaAQUHZodxzpkDJcpI5D_hVJPRxXj12UNk5aU
  • Success is an HTTP Response code. Your SESSIONS record is now deleted and you can log in again.


Fetching multiple resources in a single request using Json include

include parameter allows to include relationships and avoid additional requests.

For example, using a single request you will get the article title and authors and comments details.











URL-   GET /jsonapi/node/article?include=uid

Provide headers as shown below

  • Accept: application/vnd.api+json·
  • Content-Type: application/vnd.api+json

The following header is needed for the examples to work:

·         Authorization: Basic YXBpOmFwaQ==

If you have already  X-CSRF-Token you can send it in the header instead of providing Authorization for each request.

Retrieving single resource

using a simple GET request you can retrieve a single resource.

URL – /jsonapi/node/article/{{node_uuid}}

Sorting resource collections

You can easily sort results of getting requests using sort parameters. See below example of article entity types with sorted based on created date.

In response, the data object will be having all articles sorted based on the created date.  Old articles will be at the beginning and the newly created article will be at the end of the data object.

In my case, have 13 articles and it will be in order as provided below.

Use minus sign to get latest at the beginning of the items in data object.  Minus sign makes result in descending order.


you can use multiple sorting option as below


uid.name sorts based author username ascending order. You can use the minus sign to get results in descending order.


Normally while calling API url    /jsonapi/node/article you are receiving all the articles.  So this endpoint is called unfiltered collection endpoint.  So here we need to provide filter parameters with different conditions to reduce response size.

Here we are applying the first simple filter options.

Filter and show published content.

Parameter  – API URL – ?filter[status][value]=1

In the below case, the response will contain all published and unpublished articles.

In my case around 13 articles, details will be there in response.

We can display only published articles using the filter as shown below.

The response has six articles that are in published status.

Filter by author user name


Here admin is the user name.

And the result will contain only articles authored by user admin.

Filter based on multiple conditions and multi-value fields

Here we are going to apply multiple filters with AND and OR conditions.

First, we are going to check two conditions with AND. That is we want to display article content that is published and the author user name is admin.

So our condition will be as provided below.

WHERE user.name = admin AND node.status = 1;

So our request Url will be as below.  We are going to discuss each line and what is and-group here in detail in this section.








See the below request in postman.

Result will contain article content which is published and author user name is admin,

Now we are going to discuss in detail how this filters forms.

Conjuction will be either OR or AND.

and-group and or –group used for grouping conditions like brackets in normal statements.

In our case our statement can be written as below.

WHERE ( (user.name = admin )AND (node.status = 1;))

  1. Create a AND group




  1. Create admin filter and put in AND group




  1. Create a status filter and put in And the group




another example is shown below

WHERE (user.name = admin) AND (node.sticky = 1 OR node.promoted = 1)

See below how we can create filter options for the above statement.






















# Create an AND and an OR GROUP




# Put the OR group into the AND GROUP



# Create the admin filter and put it in the AND GROUP





# Create the sticky filter and put it in the OR GROUP





# Create the promoted filter and put it in the OR GROUP




see below some of the most used filters.

 Filter for nodes where ‘title’ CONTAINS “Foo”


Filtering on Taxonomy term values (e.g. tags)




Filtering on Date (Date only, no time)

This example is for a Date field that is set to be date only (no time).




This example is for a Date field that supports date and time.




Note that timestamp fields (like created or changed) currently must use a timestamp for filtering:
