JSONStreamingAPI - Scoped

Rversion finale: Australia

Mis à jour 12 mars 2026

19 minutes de lecture

Build a large streaming JSON payload to use in a REST or SOAP request to send bulk data to a third-party API. You can also create the payload as a JSON string for a non-streaming option.

Use these methods in the Workflow Studio script step with the sn_ih namespace identifier. For example, you can use this API to create a JSON payload in the Workflow Studio Script step and pass the returned value to the REST step to send the request to a third-party service. For more information, see the Workflow Studio Script step.

You can only use this API within the Workflow Studio environment.

To use this class, you must call the build() method in the JSONStreamingBuilder class to return a JSONStreamingAPI object. See JSONStreamingBuilder - Scoped.

API call order

Generate JSON payloads using these APIs in the following order:

JSONStreamingBuilder: Creates a builder object

Use these methods in the following order to create a builder object:

JSONStreamingBuilder(): Instantiates the JSONStreamingBuilder object.
withAttachment(): Optional. Creates the JSON object as a streaming attachment and stores it in the Streaming Attachments [streaming_attachment] table. If you do not call this method, the API creates the payload as a JSON string.
expiresAt(): Optional. Sets a time when the attachment expires. Must also call the withAttachment() method.
build(): Returns a JSONStreamingAPI object.

JSONStreamingAPI: Builds the JSON payload

Use these methods in the following order to create the JSON payload:

startObject(): Creates the parent JSON object.
Methods to generate the JSON key-value pairs, such as writeFieldName(), writeString(), and writeNumberField().
endObject(): Closes the parent JSON object.
getJSONString() or getAttachmentId(): Returns the JSON string or attachment ID that you created.
close(): Closes the JSONStreamingAPI object.

Size limits

Payloads generated through this API cannot exceed these size limits:

Attachments: 200 MB
Strings: 5 MB

Example

This example create a JSON object and stores it in the Attachment [sys_attachment] table with a defined expiration date. You can use this option to create payloads under 5 MB.

try {
  var ttl = new GlideDateTime("2011-01-01 12:00:00");
  var builder = new sn_ih.JSONStreamingBuilder()
    .withAttachment() // Creates the JSON object in streaming mode within an attachment.
    .expiresAt(ttl) // Sets an expiration date for the attachment.
    .build(); // Creates the JSONStreamingAPI object. 

  builder.startObject()  // Begins generating the JSON object.
	.writeFieldName("firstName")  // Adds a "firstName" field 
	.writeString("John")          // Writes the value of the "firstName" field
	.writeFieldName("lastName")
	.writeString("Smith")
	.writeNumberField("age","25") // Write a number field named "age" with value "25"
	.writeFieldName("address")
	.startObject()                // Start a new object nested under the parent object
		.writeStringField("streetAddress", "21 2nd Street")
		.writeStringField("city", "Santa Clara")
		.writeStringField("state", "CA")
		.writeStringField("postalCode", "11111")
	.endObject()
	.writeFieldName("phoneNumber")
	.startArray()                    // Start an array 
		.startObject()               // Add the first object to the array 
			.writeFieldName("type")
			.writeString("home")
			.writeFieldName("number")
			.writeString("212 555-1234")
		.endObject()
		.startObject()               // Add another object to the array 
			.writeFieldName("type")
			.writeString("fax")
			.writeFieldName("number")
			.writeString("646 555-4567")
		.endObject()
	.endArray()
	.endObject()

  gs.log(builder.getAttachmentId()); // Returns the sys_id of the attachment.
} 

catch (err) {
  gs.log(err);
} 

finally {
  builder.close();
}

Alternatively, this example uses the API in the Script step and creates the payload as a JSON string. You can use this option to create payloads under 5 MB.

(function execute(inputs, outputs) {

  var builder = new sn_ih.JSONStreamingBuilder().build();
  
  builder.startObject()
    .enablePrettyPrint()
    .writeFieldName("firstName")
    .writeString("John")
    .writeFieldName("lastName")
    .writeString("Smith")
    .writeNumberField("age","25")
    .writeFieldName("address")
    .startObject()
      .writeStringField("streetAddress", "21 2nd Street")
      .writeStringField("city", "Santa Clara")
      .writeStringField("state", "CA")
      .writeStringField("postalCode", "11111")
    .endObject()
    .writeFieldName("phoneNumber")
    .startArray()
      .startObject()
        .writeFieldName("type")
        .writeString("home")
        .writeFieldName("number")
        .writeString("212 555-1234")
      .endObject()
      .startObject()
        .writeFieldName("type")
        .writeString("fax")
        .writeFieldName("number")
        .writeString("646 555-4567")
      .endObject()
    .endArray()
    .endObject()

  outputs.payload = builder.getJSONString();
  
})(inputs, outputs);

Output:

{
"firstName" : "John",
"lastName" : "Smith",
"age" : 25,
"address" : {
  "streetAddress" : "21 2nd Street",
  "city" : "Santa Clara",
  "state" : "CA",
  "postalCode" : "11111"
},
"phoneNumber" : [ {
  "type" : "home",
  "number" : "212 555-1234"
}, {
  "type" : "fax",
  "number" : "646 555-4567"
} ]
}
