Description of the externalAttributes Attribute​

  1. Data Type: String.
  2. Content: Can contain representations of both simple and complex objects.
  3. Flexibility: No size restriction, allowing for a large amount of data to be included.
  4. Use: Can be utilized to transmit additional information that does not fit into other request fields.

Examples of Composition in Node.js​

To compose the externalAttributes string, you can use JavaScript objects and then convert them into a JSON string. This allows for including complex data structures in the request.

Example 1: Simple Object​

const externalAttributes = {
    userId: 12345,
    userName: "exampleUser",
    preferences: {
        theme: "dark",
        language: "pt-BR"
    }
};

const externalAttributesString = JSON.stringify(externalAttributes);

In this example, a simple JavaScript object is created with basic user properties and preferences. It is then converted into a JSON string.

Example 2: Complex Object​

const externalAttributes = {
    order: {
        id: 67890,
        items: [
            { productId: 111, quantity: 2 },
            { productId: 222, quantity: 3 }
        ],
        shippingDetails: {
            address: "Rua Exemplo, 123",
            city: "São Paulo",
            zipCode: "01234-567"
        }
    },
    userComments: "Please deliver after 6 PM."
};

const externalAttributesString = JSON.stringify(externalAttributes);

In this example, a more complex object is used, representing an order with multiple items and shipping details, along with a user comment. The entire object is then converted into a JSON string.

Example 3: Simple String​

const externalAttributesString = "Simple additional information";

Here, a simple string is used as the value for externalAttributes. This is useful for cases where a complex object is not necessary.
