GraphQL

The Flotiq API supports a GraphQL queries. It is an alternative way to REST API to get your data. We provide the complete, always up-to-date GraphQL description of your data and the endpoint which understands GraphQL queries for your Content Objects.

What is a GraphQL?

GraphQL is a query language for APIs. It is designed to make API more flexible than REST API - it is all about giving clients precisely the data they request. The developers can pull various data, in the desired shape, with a single API call.

Graphql in Flotiq

The system supports GraphQL queries for Content Objects. Endpoints that allow you to interact with the system in a GraphqQL way are:

  • GET /api/graphql/schema - get GraphQL schema,
  • POST /api/graphql - execute GraphQL query.

Authentication

To authenticate the GraphQL query, you need to use one of the Application API Keys available in your Flotiq Dashboard.

As in the whole Flotiq API, you can pass your API Key in the following way:

  • X-AUTH-TOKEN header
  • auth_token query parameter

Note

If you need more information on how to get your API Key and how to use it - go to the API access & scoped keys page.

GraphQL API endpoints are unavailable for the User Defined (scoped) API keys.

Get GraphQL Schema

To get the full GraphQL schema that describes your data you have to call the GET endpoint. It describes the shape of your current Content Type Definitions, including attribute types, required fields and relations.

Request

curl -X GET 'https://api.flotiq.com/api/graphql/schema' --header 'X-AUTH-TOKEN: YOUR_API_TOKEN'

Execute GraphQL Query

To make a query for your objects, you need to call POST /api/graphql GraphQL endpoint. We can specify two types of queries - responsible for retrieving a single object and listing objects.

Query single object

To a get single object, you need to pass the object identifier and fields you want to receive in the response. Example Query in GraphQL language to get id and title for the product with id product-1 looks like:

Graphql

query {
    products(id:"product-1") {
        id
        title
    }
}

To pass this query to the Flotiq, you need to call:

Request

curl -X POST 'https://api.flotiq.com/api/graphql' \
    --header 'X-AUTH-TOKEN: YOUR_API_TOKEN' \
    --header 'Content-Type: application/json' \
    --data-raw '{"query":"query{products(id:\"product-1\"){id,title,}}"}'

Response

{
    "data": {
        "products": {
            "id": "product-1",
            "title": "Green Tea"
        }
    }
}

List objects

While listing objects, you can use the optional parameters page, limit, order_by, order_direction, or filter.

Param name Param description Defalut value
page Number of objects on page 20
limit Number of the requested page 1
order_by What field should list be ordered by
order_direction Order direction, possible values asc, desc asc
filter Json encoded object containing conditions on which the list of CO should be filtered
Example filter value: {"title":{"type":"equals","filter":"Hello world!"}}

The below example shows how to list all products ordered by title, limited to 2 results:

Graphql

query {
    productsList(limit: 2, order_by: "title", order_direction: "asc") {
        id
        title
    }
}

To pass this query to the Flotiq, you need to call:

Request

curl -X POST 'https://api.flotiq.com/api/graphql' \
    --header 'X-AUTH-TOKEN: YOUR_API_TOKEN' \
    --header 'Content-Type: application/json' \
    --data-raw '{"query":"query {productsList(limit: 2, order_by: \"title\", order_direction: \"desc\") {id, title}}"}'

Response

{
  "data": {
    "productsList": [
      {
        "id": "product-3",
        "title": "Rooibos"
      },
      {
        "id": "product-2",
        "title": "Earl Grey"
      }
    ]
  }
}

Relation resolving (hydration)

GraphQLs flexibility also covers object relations (e.g. product has category). In Flotiq, the related objects are resolved automatically based on the type of DataSource.

For example, when we have a product object: 

{
   "id":"product-1",
   "categories":[
      {
         "dataUrl":"/api/v1/content/categories/",
         "type":"internal"
      }
   ]
}

and category: 

{
   "id": "category-1",
   "name": "Tea"
}

The GraphQL query for listing objects including categories will look like:

Graphql

query {
    productsList(limit: 1) {
        id
        title
        categories {
            id
            name
        }
    }   
}

Request

curl --request POST \
    --url 'https://api.flotiq.com/api/graphql?auth_token=__YOUR_AUTH_TOKEN__' \
    --header 'content-type: application/json' \
    --data '{"query":"query{productsList(limit:1){id,title,categories{id,name}}}"}'

Response

Will return automatically resolved relation: 

{
    "data": {
        "productsList": [
            {
                "id": "product-3",
                "title": "Rooibos",
                "categories": [
                    {
                        "id": "category-1",
                        "name": "Tea"
                    }
                ]
            }
        ]
    }
}

As you can see, the related element, category, was fetched, including its properties.

Explore using Insomnia client

GraphQL queries can be complex. To efficiently interact with Flotiq GraphQL API, we suggest you use apps like Insomnia. It helps to create queries with autocomplete, based on your current schema, validate your input and display a preview of the response.

An example query using Insomnia REST Client with endpoint https://api.flotiq.com/api/graphql?auth_token=YOUR_AUTH_TOKEN:
