Kaizen #1 - Fields in CRM #API

Kaizen #1 - Fields in CRM #API

Hey everyone, welcome to the Zoho CRM Developer Community series. The series is named 'Kaizen', meaning continuous improvement. Through these series of posts, we aim at resolving all the frequently asked questions, common hurdles, and discuss the best practices to be followed by the CRM developer community.

We have five different streams under kaizen. Each one is related to a different stream of CRM developmentAPI v2.0, Functions, SDK, Mobile Development, and Widgets. Every post will be tagged under one of these streams with a hashtag(#). Based on your area of expertise, you can choose to follow any of them. 

So, here is the drill: 
  • We will drop a few eggs of knowledge on a most discussed topic in our developer community forum, and tag it under one of the five streams. 
  • As always, you can keep the questions coming and kick start a productive discussion. 
  • The routine iterates every Friday.
Since this is our first forum post, we decided to start with something basic.

The problem


In ZohoCRM, data is organized into fields (individual chunks of data). For instance, 'First Name', 'Email', and so on. 

As we are all aware, there are multiple field types available in Zoho CRM. Each field type has its limitations on the type and length of data that can be stored in that particular field. It is essential to adhere to these restrictions while inserting, updating, upserting data. If not, it can lead to unsuccessful requests and errors. 

What you will learn from this post


In this post, we are going to walk you through the following, to give you a better idea of different field types in Zoho CRM and their role while inserting, updating, and upserting records. 

  • Different types of fields in Zoho CRM
  • Details about each field type - [ data type, limitations (what type of characters are accepted), size ]
  • Inserting records in Zoho CRM- with emphasis on fields [System-defined mandatory fields for each module]
  • A few use-cases on inserting records in Zoho CRM

a. Different types of fields in Zoho CRM


Fields are used to store data in a structured way in Zoho CRM. 

Based on how the data is stored, they are of two types:


(i) Read-only fields - For these fields, data is system generated. For instance, "created_by", "created_time", "last_activity_time", "modified_by", "modified_time", and so on. Users cannot modify these fields.
 
(ii) Read/Write fields - For these fields, data is set by the user. For instance, "first_name", "last_name", "email", and so on. 

For custom fields and default fields, you can update this property by editing the field-permissions in the set-up screen in UI. You set the fields to be either read-only, read/write, or hidden.

Note that this property cannot be altered for system-defined mandatory and custom mandatory fields.

b. Details about each field type


Just like data types available in multiple programming languages, there are multiple field types in Zoho CRM, allowing you to store different types of data about your customers, users, vendors, and so on. For instance, we have 'Single Line' field type where you can store strings, it allows you to store all the alphanumeric and special characters within a length of 255 characters. 

Apart from default fields, Zoho CRM allows you to create custom fields. Knowing about the field types is essential to pick the right kind of field type for your custom field. For instance, a 'phone' field type would be more appropriate for a custom-field that stores phone numbers than 'single line' type, since phone allows only numeric characters and '+' (to add extensions).

You can find the details about data types and restrictions about each field type in 'modules and fields' section in Zoho CRM UI. Through API, you can get the data type of the fields in a module using meta data API

URL

​​​{{api-domain-URL}}/crm/v2/settings?fields?module={module_API_name}


The following table gives you specific details about each field type in Zoho CRM and their limitations. 
The JSON type and the data type of the field-types are extracted from fields meta data API.
