JSON Generator (Mock)

Discover more about the JSON Generator (Mock) connector and how to use it on the Digibee Integration Platform.

JSON Generator (Mock) creates a JSON object. This connector accepts any input.

Parameters

Take a look at the configuration options for the connector. Parameters supported by Double Braces expressions are marked with (DB).

Parameter	Description	Default value	Data type
JSON (DB)	The JSON object that will be the output of the connector.	N/A	JSON Object
Fail on Error	If the option is activated, the pipeline's execution with an error will be interrupted. Otherwise, the pipeline execution proceeds, but the result will show a false value for the "success" property.	False	Boolean

Using Global variables

Global variables can be retrieved in the JSON Generator (Mock) connector using the following Double Braces expression:

{{global.global-name}}

You can retrieve Globals in two ways:

• As a string

• As a number

Retrieving Global variables as a string

If the Global variable’s value is a string, regardless of its category, you must enclose the Double Braces expression in double quotes.

For example, suppose you create a Global named global-email under the Email category and set an email address as its value. The Platform will interpret this value as a string. Therefore, to retrieve this Global variable in the JSON Generator (Mock) connector, structure the expression as follows:

{
    "email": "{{global.global-email}}"
}

If you don’t enclose the expression in double quotes, you will receive the following error:

{
  "timestamp": 1738778741919,
  "error": "An internal error has occurred. Exception: com.digibee.pipelineengine.exception.PipelineEngineRuntimeException: Could not parse double braces parameter json due to JSON exception: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'email': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')\n at [Source: (String)\"{\n  \"email\": [email protected]\n}\"; line: 2, column: 17]",
  "code": 500
}

This rule applies to any Global variable with a string value.

Retrieving Global variables as a number

If the Global variable’s value is a number, don’t enclose the Double Braces expression in double quotes. Otherwise, the number will be treated as a string.

For example, suppose you create a Global named global-id under the ID category and set its value to 1234.

To retrieve this Global variable as a number in the JSON Generator (Mock) connector, structure the expression as follows:

{
    "id": {{global.global-id}}
}

The output will be:

{
    "id": 1234
}

However, if you need to retrieve it as a string, simply enclose the expression in double quotes:

{
    "id": "{{global.global-id}}"
}

This will return:

{
	"id": "1234"
}

Usage example

In this example, we used the JSON Generator (Mock) connector to modify someone’s data. Here, we want to join the firstName and lastName properties into a single property called fullName. We also want to delete the phoneNumber property and add a property called country, which has the value “Brazil”.

Input

{
    “firstName” : “Carlos”,
    “lastName” : “Silva”,
    “phoneNumber” : “[phone]”
}

Parameter settings

We use the JSON Generator (Mock) connector with the following JSON parameter configuration:

{
    "fullName" : {{ CONCAT(message.firstName," ", message.lastName) }},
    "country" : "Brazil"
}

Here, we used the CONCAT Double Braces function to join the first and last names, with a blank space between them.

Output

{
    "fullName": "Carlos Silva",
    "country": "Brazil"
}
