JSON Arrays with Primitive Values

A JSON array contains zero or more ordered elements separated by commas and is enclosed in square brackets [].

In Event Publication Subscription, a JSON array can contain primitive data types, key-value pairs, JSON objects, and nested JSON arrays.

You can use primitive arrays when you need to include a list of simple values in a payload without wrapping each value in a JSON object. JSON arrays can contain the following primitive data types:

• String. For example:

  {
    "fruits": ["apple", "banana", "cherry"]
  }
  

• Number. For example:

  {
  "scores": [95, 88, 76, 85]
  }
  

• Boolean. For example:

  {
    "permissions": [true, false, true, true]
  }
  

• Null:

  {
    "values": [null, null, null]
  }
  

You can generate these payloads from Siebel server scripts or from external applications that publish events to EPS.

Examples of JSON Arrays with Primitive Values:

• JSON array with string values:

  {
    "name": [
      "abc",
      "1",
      "2"
    ]
  }
  

• Nested arrays that contain a combination of JSON objects and primitive values:

  {
    "array": [
      [
        {
          "key1": "value1"
        },
        "anotherchild"
      ],
      "abc",
      [
        "child1",
        "child2"
      ]
    ]
  }
  

• EPS also supports arrays of primitive values within object properties. For example, JSON object with primitive string elements:

  {
    "Message": {
      "Property": [
        {
          "Name": "Color",
          "Values": [
            "Blue",
            "Red",
            "Green"
          ]
        },
        {
          "Name": "Size",
          "Values": [
            "S",
            "M",
            "L"
          ]
        }
      ]
    }
  }
  

  In this example, each Property object contains a Values array with primitive string elements.

• Example of complex JSON objects and primitive values:

  {
    "bookstore": {
      "name": "Readers' Haven",
      "inventory": [
        {
          "category": "Fiction",
          "books": [
            {
              "bookId": "B001",
              "title": "The Great Gatsby",
              "editions": [
                ["Edition", "Format", "Price"],
                ["First", "Hardcover", 24.99],
                ["Second", "Paperback", 14.99]
              ]
            },
            {
              "bookId": "B002",
              "title": "1984",
              "editions": [
                ["Edition", "Format", "Price"],
                ["First", "Hardcover", 22.99],
                ["Second", "Paperback", 12.99]
              ]
            }
          ]
        }
      ]
    }
  }
