In today’s blog, we are going to look at how to work with JSON in Business Central.
JSON (JavaScript Object Notation) is a lightweight data‑exchange format that is easy for humans to read and write, and easy for machines to parse and generate. In Dynamics 365 Business Central, JSON is widely used for API integration and data exchange between systems. This versatile and efficient format enables companies to handle and manipulate structured information effectively, facilitating communication between different applications and services.
Throughout this blog, we will explore the different types of JSON data used in Business Central, how they can be created, how to read them, and practical examples.
JSON Data Types in Business Central
In Business Central, we work with several JSON data types that allow us to handle and manipulate structured information efficiently. These data types are essential for integration and data exchange between different systems and applications.
Below are the main JSON data types used in Business
JsonObject
This data type represents a JSON object. A JSON object is a collection of key‑value pairs, where each key is a string and each value can be any JSON data type, including other JSON objects. This allows data to be structured in a hierarchical and organized way.
JsonArray
Represents a JSON array. A JSON array is an ordered list of values, which can be of any JSON data type, including JSON objects and other JSON arrays. Arrays are useful for representing collections of items, such as product lists, users, or any other dataset.
JsonToken
This data type represents a JSON token. A JSON token is a basic unit of data in JSON, which can be a key, a value, or a delimiter (such as a comma or bracket). Tokens are essential for parsing and manipulating complex JSON structures.
JsonValue
Represents a JSON value. A JSON value can be a number, a string, a boolean, a JSON object, a JSON array, or even a null value. This data type is fundamental for working with individual values inside a JSON structure.
These JSON data types in Business Central provide great flexibility and power when working with structured data, enabling efficient integration with other systems and effective data manipulation.
Creating JSON
To create a JSON in Business Central, we use the JsonObject data type. Here is an example of how to create a JSON for a Sales Order:
Reading JSON
To read a JSON object, we use the ReadFrom() method of the JsonObject data type. Here is an example of how to read a JSON response from an API call:
