JSON Builder step

Create a JSON payload to use in another step. Enter values or use data pills to produce a dynamic payload. This step supports several data types, including objects and arrays for nested structures.

Roles and availability

This step requires an Integration Hub subscription. For more information, see Legal schedules - Integration Hub overview. After the required plugin is activated, the step is visible under Integrations.

Available as an Workflow Studio action step. Users with the action_designer role can create a custom action with one or more action steps.

Inputs

Provide a value for each input that your action needs. To add dynamic values, you can also drag and drop pills from the Data panel or select them from the pill picker.

Name

Data type: String

Name part of a name-value pair. Enter a value or use a data pill to produce a dynamic payload.

Value

Data type: String

Value part of a name-value pair. Enter a value or use a data pill to produce a dynamic payload. You can use a complex object pill to populate a row with an object data type, but doing so deletes any children the complex object pill already has.

Type

Data type: Choice

Data type for the name-value pair. If you're using a data pill for the name or value, make sure the data type for the pill matches the data type selected here. The options are:

• String
• Object
• Number
• Boolean
• Array

For arrays and objects, use the plus icon () to add name-value pairs to the array or object.

In case of empty value

Data type: Choice

Option to specify what to do if a name-value pair has an empty or null value.

• Leave as is: Keeps the empty or null value as an empty string.
• Omit property: Excludes a name-value pair if the value is empty or null.
• Set as null: Returns an empty or null value as a null data type.
• Throw error: Returns an error if a name-value pair has an empty or null value.

Include Outer Structure

Data type: True/False

Option to include the curly braces for a top-level JSON container.

Omit Empty Structure

Data type: True/False

Option to omit an empty payload. Empty payloads can occur when you select Omit property for the In case of empty value input for every name-value pair and all name-value pairs in the payload produce empty values.

Structure

Data type: Structure

Read-only payload the step produces.

If this step fails

Data type: Choice

Option to continue running the next step or go to error evaluation. To use the step status code or message for a custom action error condition, see Action error evaluation.

Outputs

These outputs appear in the Data panel. You can use them as inputs elsewhere in your action.

Output

Data type: String

JSON payload as a string. If you want to use the payload as an object, you can use the JSON parser step to parse the string.

Step Status

Data type: Object

Object data pill containing runtime details about the step. Each step in an action returns a Step Status.

Step Status > Code

Data type: Integer

Integer data pill indicating whether the step produced an error. By default, a value of 1 indicates that the step produced an error. A value of 0 indicates that the step ran successfully. You can't customize these codes.

Step Status > Message

Data type: String

String data pill containing the error message produced by the step or system operation. You can't customize this message.

Generate a JSON Payload

Automatically generate a JSON payload with the Add JSON for Payload button. This button opens the Add Payload script editor where you can enter a JSON payload to be automatically de-serialized into structured input.

There are a few details to be aware of when using the JSON payload generator.

• If the JSON has empty keys, the payload is still generated.
• If there are duplicate keys in the script editor, the last key entry in the object overrides the value of any previous keys with the same name.
• If the root object is an array, the root array is wrapped into a root object.
• If an array contains multiple objects, all the keys in the objects are coalesced into one parent object.

The JSON payload generator doesn’t support the following.

• empty payloads
• non-complex object types
• invalid JSON
• empty root objects, such as an empty array
• payloads larger than 65,000 bytes

Note:

Generating a JSON payload overrides any existing structures in the JSON Builder step.
