Hi all,
Hello and welcome to another week of Kaizen!
In this post, we will be discussing Frequently Asked Questions on Zoho CRM GraphQL APIs.  GraphQL is a query language that provides a more flexible and efficient way to access data and metadata within your Zoho CRM organization. 

Why should I try GraphQL APIs?

 Using GraphQL with Zoho CRM allows you to fetch exactly the data you need in a single request, reducing over-fetching and under-fetching. It also enables you to combine multiple operations in one request, which can improve performance and reduce network overhead.

How do I authorize GraphQL requests?

Similar to Zoho CRM REST APIs, GraphQL APIs use OAuth 2.0 for authorization.
For self-clients, you can use the self-client option in the API console to get an authorization grant code. This code can be exchanged for an access token and a refresh token. Once you receive the access token, send the token in your HTTP authorization header with the value "Zoho-oauthtoken {access_token}" for each request. Check out our Postman collection for GraphQL APIs for examples.

Are GraphQL APIs available for all Zoho CRM editions?

GraphQL APIs are available in Enterprise, Zoho One Enterprise, CRM Plus and Ultimate edition of Zoho CRM. Note that it is not available in any trial editions.

What is the difference between REST APIs and GraphQL APIs?

REST APIs let clients talk to servers using standard HTTP methods such as GET, POST, PUT, PATCH, and DELETE. Instead of fetching a fixed dataset like with REST, GraphQL APIs allows you to ask for precisely the data you want. We have covered this topic in detail in our previous Kaizen post that compares REST APIs and GraphQL APIs

Do I need to do any initial setup to start using GraphQL APIs?

To start using GraphQL APIs, you have to enable GraphQL APIs for your Zoho CRM profile through the enable GraphQL API call. 
  • Request URL : {api-domain}/crm/graphql/actions/enable
  • Method : POST
  • Scope: ZohoCRM.GraphQL.UPDATE
This API call generates the GraphQL schema. GraphQL schema defines the capabilities of a server, the data it contains and the actions that can be done on it. Note that it is sufficient to invoke this API call once for each profile. 

What are the operations supported in Zoho CRM GraphQL APIs?

   Currently, Zoho CRM GraphQL APIs support only query operations. Query operation is analogous to the GET method in REST APIs.

How do I configure requests for Zoho CRM’s GraphQL APIs?

How do I write a basic query in GraphQL? 

The below query can be used to fetch Last_Name in Leads module.

Request body 

query {

    Records {

        Leads {_data {Last_Name {value}}}

    }

}

 

Output 

{"data":{"Records":{"Leads":{"_data":[

  {"Last_Name":{"value":"Kitzman"}},

  {"Last_Name":{"value":"Frey"}}

  // ...

]}}}}


What are the supported metadata types that can be fetched using GraphQL APIs?

Using GraphQL APIs you can fetch metadata from Modules, Users, KanbanView, UserProperties, ProfilePermissions, Profiles, Roles, and Widgets

Can I fetch metadata and data of a particular module in a single query using GraphQL APIs?

Yes, using GraphQL it is possible to fetch both metadata and data in a single query. 
 For example, the below query can be used to fetch Last_Name from Leads module and metadata information of the Last_Name field in the Leads module.

Request body

{

  Records {

    Leads { _data { Last_Name { value } } }

  }

  Meta {

    Modules(filter: { api_name: "Leads" }) {

      _data {

        fields(filter: { api_names: "Last_Name" }) {

_data {

                        id

                        api_name

                        display_label

                        json_type

                        data_type

}}}}}}

 

 Output 

{

  "data": {

    "Records": {

      "Leads": {

        "_data": [

          { "Last_Name": { "value": "Kitzman" } },

          { "Last_Name": { "value": "Frey" } }

          // ...

        ]

      }

    },

    "Meta": {

      "Modules": {

        "_data": [

          {

            "fields": {

              "_data": [

                {

                  "id": "6660682000000002595",

                  "api_name": "Last_Name",

                  "display_label": "Last Name",

                  "json_type": "string",

                  "data_type": "text"

   }]}}]}}}}

 

We have covered this in detail in this Kaizen post: Using GraphQL APIs to fetch data in a consolidated way.

Are there any limits applicable for a GraphQL API query?

Yes, Zoho CRM imposes certain limits on the GraphQL API to ensure fair usage. 
  • Credits: A single query can consume up to a maximum of 10 credits
  • Complexity: Complexity is a measure of workload a query exerts on the server based on the number of fields and depth of the query. The maximum complexity allowed for a single query is 1000. 
  • Depth: The nesting level of a queried field is referred to as depth. The limit for metadata is seven, and for data is three.
Refer to the official documentation on GraphQL credits.

Is it possible to retrieve selective data using GraphQL APIs?

Records

You can use the where argument to filter records from each module.  Each field can support type specific operators and can be combined with Boolean logic and wildcards.

For example. to fetch Email, Last_Name, ID, Phone and Mobile of  contacts where last name starts with "Ni" and mobile contains the digit 5 or phone number equals 555-678-9999

Request body

{

  Records {

    Contacts(where: {

      and: [

        { Last_Name: { like: "Ni%" } },

        {

          or: [

            { Phone: { equals: "555-678-9999" } },

            { Mobile: { like: "%5%" } }

          ]

        }

      ]

    }) {

      _data {

        Email { value }

        Last_Name { value }

        id { value }

        Phone { value }

        Mobile { value }

  }}}}

 

Introspecting the GraphQL schema in Postman will reveal the details of fields and supported operators for each module. Check out our previous Kaizen, where we explained this using videos.

Metadata

You can use the filter argument to filter metadata resources.

For example, the query below fetches metadata of Deals module and api_name of its layouts and fields

Request body

query {

  Meta {

    Modules(filter: { api_name: "Deals" }) {

      _data {

        id

        singular_label

        plural_label

        layouts {

          _data {

            id

            api_name

          }

        }

        fields {

          _data {

            api_name

     }}}}}}

How do I paginate results in GraphQL?

In GraphQL, we use the offset and limit argument to paginate results.
You can use offset to fetch the next page of results by passing the value from your previous response, starting with null for the initial set.  For each page, the number of records has a limit: up to 100 records for root queries or 10 for nested data.
The value to be passed in offset is obtained by querying for previous_offset and next_offset inside _info object.

Is it possible to sort records in GraphQL? 

The order_by argument can be used to sort the response set after fetching records to ascending or descending order.

For example, the below query fetches the fields Deal_Name, Expected_Revenue, and Probability from Deals module in descending order of probability.


Request body

query {

  Records {

    Deals(order_by: { Probability: { order: DESC } }) {

      _data {

        Deal_Name { value }

        Expected_Revenue { value }

        Probability { value }

}}}}

When should I choose Zoho CRM GraphQL APIs over Zoho CRM REST APIs, and vice versa? 

Use Zoho CRM GraphQL APIs when:

  • You need to fetch complex, nested data from multiple resources (e.g., accounts with linked contacts and deals) in a single request and avoid under-fetching of required data/metadata.

  • You need to minimize over-fetching of data/metadata by selecting only specific resources, fields of the resources, and relationships of the resources.

  • You need to query data and metadata together efficiently. 

Use Zoho CRM REST APIs when :

  • You need to perform simple CRUD operations (e.g., fetch/update a single product).

  • Your use case involves straightforward endpoints without nested data/metadata.

  • You need to do add/update/delete operations.

We trust that this post addressed your doubts on GraphQL APIs. If you have any questions please let us know in the comment section or reach out to us at support@zohocrm.com.
